  3. ICE AGE What you’ll learn; What is an ice age? How ice ages form? When/why they occur? Interesting facts

  4. ICE AGE What is an Ice Age? A cold period marked by episodes of extinctive glaciations alternating with episodes of relative warmth. An ice age is a relatively cool period in Earth history, when vast ice sheets cover much of Earth’s land surface. There have been at least five major ice ages during the last billion years. The most recent ice age began 2.5 million years ago.

  5. ICE AGE How Ice Ages form? - During the Quaternary Period high latitude Winters have been cold enough for snow to accumulate excessively . - During this time the summer’s are cold because the Sun is at its farthest point in the Earth’s orbit. - This means that the snow never melts from the other winters. - This will go on for centuries and ice sheets will begin to form.

  6. ICE AGE - Ice ages have occurred about two million years ago which had cold (glacial), and relatively warm (interglacial phases) When/why do Ice Ages occur? When… - The most recent ice age was about 70 thousand years ago and ended about 10 thousand years ago. - About 97% of Canada was covered by ice. - The thickest areas of ice was in Hudson Bay with approximately 3,300 meters deep. - Currently we are in an interglacial phase that will last another 10 000 or more years - INTERGLACIAL: ‘A comparatively short period of warmth during an overall period of glaciations.’

  7. ICE AGE 97% of Canada was covered!

  8. ICE AGE - There are four major factors why we have Ice Ages: Why… - #1, The earth’s axis is wobbly, much like a spinning top that’s wobbles after it slows down. This wobble can go up to 23.5 degrees on either side of the axis. Depending on the tilt depends on the amount of sunlight going into different parts of the earth. - #2, The greater the tilt, the stronger the difference in seasons. (i.e., more tilt equals sharper differences between summer and winter temperatures. - #3, This process takes over 41 thousand years. - #4, This also changes the earths path on its elliptical path. The process is called “precession of equinoxes. This process takes 23,000 years to complete. During this time the ice sheets would form.

  11. ICE AGE Interesting Facts: • Animals that lived through the ice age: • Wolly Mammoths • Saber Toothed Cats • Coelodonta • Deodircurus • Elasmotherium • Glyphtodon • Smilodon

  12. ICE AGE Interesting Facts: Believe it or not Humans actually lived though the Ice Age. Many lived in caves where they have left stone relics. They would communicate using signs and symbols. Mostly they would eat stuff they would hunt or plants they could find.

  19. QUESTION #3 Q: Name one reason ice ages formed A:- During the Quaternary Period high latitude Winters have been cold enough for snow to accumulate excessively . - During this time the summer’s are cold because the Sun is at its farthest point in the Earth’s orbit. - This means that the snow never melts from the other winters. - This will go on for centuries and ice sheets will begin to form.
