GlaciersA Cesar Melendez Presentation
What is a Glacier?• A mass of ice accumulating
over the years on land from the recrystallization and compaction of snow, slowly deforming and flowing due to stresses induced by their weight, creating crevasses, seracs, and other distinguishing features.• Glaciers take up 10% of
the words land and 75% of the worlds Freshwaters .
Three principle types of glaciers:
Cirque Glacier that resides in Basins or Amphitheaters near ridge crests.
Valley Glacier confined to a valley usually formed from streams.
Continental ice sheet largest of glaciers that cover thousands of square kilometers found only in Greenland and Antarctica.
Where are they located?Most of the world's glacial ice is found in Antarctica and GreenlandContinents are • Africa• Antarctica• Asia• Europe • North and South
America • Oceania
Three of the largest Glaciers Central Asia at 114,800 Sq. kilometers(44,325 miles)
North America 124,00 Sq. kilometers (47,877 square miles)
Artic Islands (not including Green land)275, Square kilometers(106,371 Square miles)
How does it affect life on Earth? Or how is life on Earth affected by it?- Glacier melting water provides many regions with fresh
drinking water. - They create homes, ecosystems, and habitats for many
organism in our animal kingdom. - The melt water AKA rundown of Glacier water provides energy
resources to certain countries. - They provide water to dessert regions.
How does it affect life on Earth? Or how is life on Earth affected by it?
Glaciers are being threatened everyday!
The biggest threat to Glaciers is Global Warming
- Global warming is melting our Glaciers creating sea levels to rise dramatically
- Melting Glaciers also means that the habitants will lose their home and way of life creating tragedy in ecosystems across the world.
- Many regions will lose their fresh water source- Many regions near the oceans and seas will become
flooded and non-existent.
What are some solutions?Find energy resources that do not produce greenhouse gases
- Contribute to the cause of eliminating green house gases by monitoring your personal carbon footprint
- Corporations need and should adopt environmental ethics and promote and implement better measures to reduce greenhouse gases
- People should look into alternate energy resources that do emit green house gases into the atmosphere such has solar and turbine energy.
