Aurora is an electro-static phenomenon, characterised by a bright glow and caused by the collision of charged
particles in the magnetosphere with atoms in the Earth’s upper atmosphere.
![Page 16: Explanation Text](https://reader031.fdocument.pub/reader031/viewer/2022012310/55ad99561a28ab024b8b4607/html5/thumbnails/16.jpg)
Ultimately, the source lies in the solar wind, a fast-moving stream of particles
constantly flowing from the Sun that carries the Sun’s magnetic field out into
space. The solar wind, typically moving at 250 miles (400 kilometers) per second, flows past Earth’s magnetic field and molds it into an elongated bubble or
cavity, compressing its sunward side and stretching its night side far beyond the
Moon’s orbit.
![Page 17: Explanation Text](https://reader031.fdocument.pub/reader031/viewer/2022012310/55ad99561a28ab024b8b4607/html5/thumbnails/17.jpg)
Under certain conditions, the solar wind’s magnetic field can merge with Earth’s, creating electrical currents that drive protons and electrons into the polar
atmosphere. Powerful events occurring on the Sun can drive enormous changes in the solar wind, increasing both its speed and density and enhancing its effect on Earth.
![Page 18: Explanation Text](https://reader031.fdocument.pub/reader031/viewer/2022012310/55ad99561a28ab024b8b4607/html5/thumbnails/18.jpg)
An aurora is usually observed in the night sky, particularly in the polar zone. For this latter reason, some scientists call it a “polar aurora”
(aurora polaris). Aurora Coloured light in the night sky
near the Earth’s magnetic poles, called aurora borealis (northern
lights) in the northern hemisphere and aurora australis (southern lights) in
the southern hemisphere.
![Page 19: Explanation Text](https://reader031.fdocument.pub/reader031/viewer/2022012310/55ad99561a28ab024b8b4607/html5/thumbnails/19.jpg)
Northern lights is the name of a light phenomenon often seen in the northern regions. The lights have been around since Earth formed an atmosphere The scientific name for the phenomenon is “Aurora Borealis”, aurora for short.

The southern lights or aurora australis, most commonly seen in southern New Zealand. It shows a typical red and green aurora, the nearly vertical rays tracing the earth’s magnetic field lines.

WHAT IS A RAINBOW?
A rainbow is an optical and
meteorological phenomenon that is
caused by both reflection and
refraction of light in water droplets
in the Earth's atmosphere, resulting
in a spectrum of light appearing in
the sky.
![Page 25: Explanation Text](https://reader031.fdocument.pub/reader031/viewer/2022012310/55ad99561a28ab024b8b4607/html5/thumbnails/25.jpg)
OVERVIEW A rainbow spans a continuous spectrum of colours. Any distinct bands perceived are an artifact of human colour vision, and no banding of any type is seen in a black-and-white photo of a rainbow, only a smooth gradation of intensity to a maximum, then fading towards the other side. For colours seen by the human eye, the most commonly cited and remembered sequence is Newton's sevenfold red, orange, yellow, green, blue, indigo and violet.
Rainbows can be caused by many forms of airborne water. These include not only rain, but also mist, spray, and airborne dew.
![Page 26: Explanation Text](https://reader031.fdocument.pub/reader031/viewer/2022012310/55ad99561a28ab024b8b4607/html5/thumbnails/26.jpg)
WHEN CAN WE SEE RAINBOW? Rainbows can be observed whenever there are water drops in the air and sunlight shining from behind at a low altitude angle. The most spectacular rainbow displays happen when half the sky is still dark with raining clouds and the observer is at a spot with clear sky in the direction of the sun. The result is a luminous rainbow that contrasts with the darkened background.
![Page 27: Explanation Text](https://reader031.fdocument.pub/reader031/viewer/2022012310/55ad99561a28ab024b8b4607/html5/thumbnails/27.jpg)
HOW DOES IT LOOKS? The colour pattern of a
rainbow is different from
a spectrum, and the
colours are less
saturated. There is
spectral smearing in a
rainbow owing to the
fact that for any
particular wavelength,
there is a distribution of
exit angles, rather than a
single unvarying angle.

FATHERS OF RAINBOW.. • The classical Greek scholar Aristotle (384–322 BC)
was first to devote serious attention to the rainbow.
• In the Naturales Quaestiones (ca. 65 AD), the Roman
philosopher Seneca the Younger devotes a whole book
to rainbows, heaping up a number of observations and
hypotheses.
• According to Hüseyin Gazi Topdemir, the Persian
physicist and polymath Ibn al-Haytham (Alhazen;
965–1039), attempted to provide a scientific
explanation for the rainbow phenomenon.
![Page 37: Explanation Text](https://reader031.fdocument.pub/reader031/viewer/2022012310/55ad99561a28ab024b8b4607/html5/thumbnails/37.jpg)
LOTS OF FATHERS, RIGHT?
• In Song Dynasty China (960–1279), a polymathic scholar-
official named Shen Kuo (1031–1095) hypothesized that
rainbows were formed by a phenomenon of sunlight
encountering droplets of rain in the air.
• According to Nader El-Bizri, the Persian astronomer, Qutb
al-Din al-Shirazi (1236–1311), gave a fairly accurate
explanation for the rainbow phenomenon.
• Theodoric of Freiberg is known to have given an accurate
theoretical explanation of both the primary and secondary
rainbows in 1307.
• Descartes' 1637 treatise, Discourse on Method, further
advanced this explanation.
• Modern physical descriptions of the rainbow are based on
Mie scattering, work published by Gustav Mie in 1908.

RAINBOW IN CULTURE Rainbows form a significant part of human culture. They occur frequently in mythology, and have been used in the arts. Rainbow flags have been used as a symbol of hope or social change for centuries, featuring as a symbol of the Cooperative movement in the German Peasants' War in the 16th century, as a symbol of peace in Italy, and as a symbol of gay pride and LGBT social movements since the 1970s.
![Page 39: Explanation Text](https://reader031.fdocument.pub/reader031/viewer/2022012310/55ad99561a28ab024b8b4607/html5/thumbnails/39.jpg)
RAINBOW IN MYTHOLOGY • In Greco-Roman mythology, the rainbow was considered to be a path
made by a messenger (Iris) between Earth and Heaven.
• In Chinese mythology, the rainbow was a slit in the sky sealed by
goddess Nüwa using stones of five different colours.
• In Hindu religion, the rainbow is called Indradhanush, meaning "the bow
of Indra, the god of lightning, thunder and rain".
• In Armenian mythology the rainbow is a belt of Tir, a Sun god.
• In Norse Mythology, a rainbow called the Bifröst Bridge connects the
realms of Ásgard and Midgard, homes of the gods and humans,
respectively.
• In New Age and Hindu philosophy, the seven colours of the rainbow
represent the seven chakras, from the first chakra (red) to the
seventh chakra (violet).

As a device of excretion, the kidney has a role in the process of urine formation. Urine is a liquid that contains substances which are not used by the body and then it’ll be excreted through the urethra. The process of formation of urine occurs through the three stages, namely filtration, reabsorption, and augmentation.
Before that, the blood carries remains of metabolism, protein will get into the kidney through the bloodstream and then it’ll come into the glomerular.

In the glomerular, the substances of the blood will be refined. The substances that can pass the glomerular filter are substances that have small molecule, such as water, salts, ammonia, urea, and sugar. Then, they called filtranglomerulus. Filtranglomerulus get into the Bowman's capsule and it’ll be accommodated. Then it will be continued to the proximal tubule.
![Page 50: Explanation Text](https://reader031.fdocument.pub/reader031/viewer/2022012310/55ad99561a28ab024b8b4607/html5/thumbnails/50.jpg)
In the proximal tubule, reabsorption of substances (that are still required) will occur, namely glucose, ammonia, salt, and sugar. And in the Henle’s curve, substances that are reabsorpted, such as water, K, Fe, and Na. While the other substances that are not absorbed will become the primary urine.
![Page 51: Explanation Text](https://reader031.fdocument.pub/reader031/viewer/2022012310/55ad99561a28ab024b8b4607/html5/thumbnails/51.jpg)
The primary urine get into the distal tubule and will happen augmentation, the addition of substances that are not used to the primary urine to become the secondary urine. The secondary urine is the real urine.
Secondary urine is accommodated in the colecta tubule, then it’ll be continued to the ureter and it’s reaccommodated in the bag before it’s excreted from the body through the urethra.

The process of urine formation occurs through three steps, namely filtration, reabsorption, and augmentation. The final result of it is the secondary urine that contains substances which are not used by human body.

Tsunamis, on the other hand, can be caused by a few different means:
earthquake
a large-scale undersea landslide
a submarine volcanic eruption
a large meteor or asteroid impact at sea

How Earthquakes Cause Tsunamis The illustration below shows a subduction earthquake
(one where a denser plates shifts below its neighboring plate, at left). Energy is transferred and the displaced water forms a wave. As the wave travels and enters shallower water in the coastal area, it begins to increase in amplitude.

How Landslides Cause Tsunamis
Landslides are similar to volcanoes that avalanche into the sea. They occur in the water and often are triggered by earthquakes. There is an instance in 1958 where a tsunami was caused by rockfall in Lituya Bay, Alaska. In this instance, a gigantic boulder was loosed by an earthquake and fell into the bay causing a tsunami that went out to sea.

How Volcanic eruptions Cause Tsunamis
There are two different ways that volcanoes can cause seismic
waves. One possibility is for a land-based volcano to break down and collapse, forcing large amounts of ash and debris into the water. This sudden change and displacement of the water column transfers to kinetic energy and results in waves

Tsunamis can cause as follows :
1. They can destroy lives/drowned loved ones.
2. Wash away properties.
3. Wash away and drowned pets.
4. The sound will make you scared and after it happens you might not be able to sleep well because you might hear the sound of a tsunami at night.
5. You won’t have anything to live like: Food, clothes, shelter, beds and blankets.

Closing
The term tsunami has its origins in the Japanese language; an English equivalent is "seismic sea waves." Tsunamis are often incorrectly interchanged with the term" tidal waves," which refer to high waves of water caused by changes in the flow and surge of the ocean. Tsunamis, on the other hand, can be caused by a few different means. And than tsunami also have many effect for us.

How does the Tornado Occur?
![Page 78: Explanation Text](https://reader031.fdocument.pub/reader031/viewer/2022012310/55ad99561a28ab024b8b4607/html5/thumbnails/78.jpg)
Tornado is the most damaging storm. In the Sumatra region is called "Wind Bohorok" and there are still other designations. Tornadoes often occur in the afternoon or evening on the season of transition. Tornado is air column which rotate very fast and form relation between cumulonimbus cloud. Tornado usually has wind velocity between 177 km/hours or more with reach average 75 meters and attack several kilometers before disappearing. Characteristics of a tornado is coming in the daytime view the white clouds that towered like cauliflower, then develop into dark clouds with cold air blowing, and the trees are begun to shake by the wind to the left and right, not long before the faster winds and heavy rain followed by and sometimes accompanied by hail.
![Page 79: Explanation Text](https://reader031.fdocument.pub/reader031/viewer/2022012310/55ad99561a28ab024b8b4607/html5/thumbnails/79.jpg)
Before tornado happens, it has several signal. First, the sky seems dark. Then happen ice rain around the area, usually 20-25 minutes. After that, the situation will calm, but the sky become darker. Fourth, cloud moving around the area. Fifth, the sound of tornado heard. At the beginning, the sound like water fall, but in the process of time it will change until like jet plane which is very loud
![Page 80: Explanation Text](https://reader031.fdocument.pub/reader031/viewer/2022012310/55ad99561a28ab024b8b4607/html5/thumbnails/80.jpg)
There is a clear set of steps in the formation of a tornado. First, just before the thunderstorm develops, a change in wind direction and an increase in wind speed, at an increasing altitude, creates an invisible horizontal spinning effect in the lower atmosphere. Wind sliding is created by when winds at two different altitudes blow at two different speeds. It is one way the rotation appears to happen.
![Page 81: Explanation Text](https://reader031.fdocument.pub/reader031/viewer/2022012310/55ad99561a28ab024b8b4607/html5/thumbnails/81.jpg)
Second, rising air within the thunderstorm’s updraft tilts and the air rotating from horizontal to vertical. Next, An area of rotation, 2-6 miles wide is contained within a vast majority of the storm. The strongest, most violent tornadoes form within this area of rotation. After that, a lower cloud base in the center of the storm becomes a rotating wall cloud.
![Page 82: Explanation Text](https://reader031.fdocument.pub/reader031/viewer/2022012310/55ad99561a28ab024b8b4607/html5/thumbnails/82.jpg)
Tornado is created by the rain and hail in the thunderstorm and makes the funnel to touch down. Lastly, just a very few minutes later, a tornado develops and starts to wreak its destruction.

MATURITY
1. The water dots not restrained by
air up to the clouds.
2. It rains caused the string between rising
air currents and down. The mass of air temperature down is
cooler than its air.
3. Between air currents up and down may arise
whirling the current slide
forming a vortex.
4. A current of air whirling faster, this
resembling a cyclone that "bootlick" the
earth as wind waterspout.

DDEMISE
No air mass up . The mass of
air down extends across
the clouds.
Condensation stop.
Air down weaken to cloud growth

Based on the explanation above, tornado is the most damaging storm. The tornado is formed by during the storm cold air and warm air combine. The cold air goes drops as the warm air rises. The warm air eventually twists into a spiral and forms a funnel cloud. The sky turns a very dark color and the tornado begins its destruction. There’re so much the negative effect of tornado more than the positive of it.

The water cycle or hydrologic is a continuous cycle
where water evaporates, travels into the air and becomes
part of a cloud, falls down to earth as precipitation, and then
evaporates again. This repeats again and again in a never-
ending cycle. As water goes through its cycle, it can be a
solid (ice), a liquid (water), or a gas (water vapor). Ice can
change to become water or water vapor. Water can change
to become ice or water vapor. Water vapor can change to
become ice or water.
![Page 95: Explanation Text](https://reader031.fdocument.pub/reader031/viewer/2022012310/55ad99561a28ab024b8b4607/html5/thumbnails/95.jpg)
• Humans use water for drinking, respiration, perspiration, and
elimination of wastes are all part of this cycle
• Large amounts of water are needed for most economic
activities: agriculture and mining, food processing,
manufacturing
• Lakes and rivers provide towns and cities with a means of
discharging wastes
• Generation of electricity from thermal power plants
• Waterways provide transportation
• Recreational activities
• Some people view the rivers and large lakes of this country as
a part of their own identity

It happens when the temperature and the
atmospheric pressure are right. Larger droplets
and precipitation occur is formed by the small
droplets of water in clouds. The raindrops fall
to earth occurs when so much water has
condensed that the air cannot hold it anymore.
The clouds get heavy and water falls back to
the earth in the form of rain, hail, sleet or snow
![Page 99: Explanation Text](https://reader031.fdocument.pub/reader031/viewer/2022012310/55ad99561a28ab024b8b4607/html5/thumbnails/99.jpg)
Important process where
rain water soaks into the
ground, through the soil
and underlying rock layers.
The flow of water from the
ground surface into the
ground. Once infiltrated, the
water becomes soil
moisture or groundwater.
![Page 100: Explanation Text](https://reader031.fdocument.pub/reader031/viewer/2022012310/55ad99561a28ab024b8b4607/html5/thumbnails/100.jpg)
Movement of water underground is called
groundwater flow . The spaces and cracks
particles between the soil is moved by
groundwater slowly on its journey to lower
elevations.
![Page 101: Explanation Text](https://reader031.fdocument.pub/reader031/viewer/2022012310/55ad99561a28ab024b8b4607/html5/thumbnails/101.jpg)
The movement of land water to the oceans,
mainly in the form of rivers, lakes, and streams,
consists of precipitation that neither
evaporates, transpires nor penetrates the
surface to become groundwater. Excess runoff
can lead to flooding, which occurs when there
is too much precipitation
![Page 102: Explanation Text](https://reader031.fdocument.pub/reader031/viewer/2022012310/55ad99561a28ab024b8b4607/html5/thumbnails/102.jpg)
A process that
happens through plants.
Water from the soil is
absorbed by the plants,
the roots through the
stems to the leaves are
moved by the water. Once
the leaves are reached by
the water, some of it
evaporates from the
leaves, adding to the
amount of water vapor in
the air.
![Page 103: Explanation Text](https://reader031.fdocument.pub/reader031/viewer/2022012310/55ad99561a28ab024b8b4607/html5/thumbnails/103.jpg)
The process where a liquid, in this case water,
changes from its liquid state to a gaseous state.
Water in rivers or lakes or the ocean and turn it
into vapor or steam are heated up by the sun. The
water vapor or steam then leaves the river, lake,
or ocean and goes into the air.
![Page 104: Explanation Text](https://reader031.fdocument.pub/reader031/viewer/2022012310/55ad99561a28ab024b8b4607/html5/thumbnails/104.jpg)
Water in its gaseous state-instead of liquid
or solid (ice) is totally invisible, extremely
important to the weather and climate. Without it,
there would be no clouds or rain or snow. All of
the water vapor that evaporates from the
surface of the Earth eventually returns as
precipitation - rain or snow.
![Page 105: Explanation Text](https://reader031.fdocument.pub/reader031/viewer/2022012310/55ad99561a28ab024b8b4607/html5/thumbnails/105.jpg)
Formation of liquid drops from water vapor
occurs when a parcel of rising air expands and
cools. These clouds may produce precipitation,
which is the primary route for water to return to
the Earth's surface within the water cycle
![Page 106: Explanation Text](https://reader031.fdocument.pub/reader031/viewer/2022012310/55ad99561a28ab024b8b4607/html5/thumbnails/106.jpg)
When water falls back to earth as
precipitation, it may fall back in the oceans,
lakes or rivers or it may end up on land. When it
ends up on land, it will either be soaked into the
earth and become part of the “ground water”
that plants and animals use to drink. It may run
over the soil and collect in the oceans, lakes or
rivers where the cycle starts all over again.
![Page 107: Explanation Text](https://reader031.fdocument.pub/reader031/viewer/2022012310/55ad99561a28ab024b8b4607/html5/thumbnails/107.jpg)
The water cycle is called the hydrologic cycle. In the hydrologic
cycle, water from oceans, lakes, swamps, rivers, plants, and even you,
can turn into water vapor. Water vapor condenses into millions of tiny
droplets that form clouds. Clouds lose their water as rain or snow,
which is called precipitation. Precipitation is either absorbed into the
ground or runs off into rivers. Water that was absorbed into the
ground is taken up by plants. Plants lose water from their surfaces as
vapor back into the atmosphere. Water that runs off into rivers flows
into ponds, lakes, or oceans where it evaporates back into the
atmosphere. The cycle continues.
