you should specify which ice age; there have been hundreds. As far as why, that is a great question, and I don't think anyone has the answer. Ice ages are tied pretty close with atmospheric carbon dioxide levels. Carbon dioxide, you have probably heard, is a greenhouse gas, meaning it traps heat on earth and helps warm it up. Most carbon dioxide is absorbed by the ocean, but the ocean also re-releases a good amount. When ocean water freezes, it pulls the carbon dioxide out of the atmosphere and traps it, and the earth gets a little cooler. The more ice, the more carbon dioxide trapped, the cooler the earth, the more ice, and so forth. Hope this helps.
Lots and lots of ice. Others say its possible that a supervolcano erupted, causing a temporary volcanic winter, which thus spread ice, which reflected sunlight, which caused the ice age. But that's theory.
when the climate cools enough, large areas of earth are covered by sheets of ice, or glaciers.
ice started to melt

A warming trend brought an end to the ice ages.
Ice ages are when a huge clump of ice is built up together and stay frozen for a bunch of years.....they most likely happen is because the ice just builds up and its too cold for the ice to melt...if it so happen did,it would become an ocean.
one is hot an ice ages are cold
no.
Earth's Precession
Sometimes continental drifts cause ice ages. Most of the time they are caused when ice glaciers cover parts of the Earth.
true
Ice ages are related to geography by being from a long time ago, the geographers study exactly how long ago the ice ages were and that leads a connection in ice ages and geography.
Ice Ages - band - was created in 1994.
The ice age caused the area between Russia and Alaska to freeze into ice that people could walk on but the Asian hunters also followed the bison to the Americas for food

by ice melting
Over time, their have been many ice ages
Ice.
there were 200 years between ice ages, there were 201 when it ended on a leap year.
