Stories of Our Earth: Ice Ages and Their Impact on GeographyJust a few weeks ago we were complaining that winter was so cold and it didn't would never end up in Canada; but imagine living in the Ice Age, where there was a time when glaciers, large masses of ice, covered a huge portion of the Earth's surface. Studies show that polar ice caps, as we know them today, covered about 30% of Earth during our last ice age. The Earth remained in this state for thousands and thousands of years. Cold, right? According to geologists, there have been a total of about 5 major ice ages. They began to appear about 2,300,000 years ago, until the most recent, about 10,000 years ago; it was the ice age/ice age, and that's exactly what happened. Ice ages are times when temperatures around the world, including Earth's atmosphere and surface, were consistently cold for more than several thousand years. Unlike today's average temperature of 220°C, ice ages were much colder, averaging around 50°C. Although geographers do not all agree on a theory as to why ice ages may have occurred, there are a few theories that many believe could have caused the ice ages to begin. One of the main theories about the cause of the Ice Age involves the idea of ​​another theory, the theory of plate tectonics, which proposes that the Earth's surface, divided into plates, is constantly in motion. The theory suggests that the Earth's plates moved away from the equator where it is generally warm, and towards a colder place, an area where the sun's rays were not very strong, making the very cold earth. This is a logical theory located in the middle of the document......rumlins http://allyouneedtoknowaboutglaciers.weebly.com/stratified-drift.html http://www.bbc.co.uk/schools/ gcsebitesize/geography/glacial_landscapes/glaciation_rev2.shtml http://www.museum.state.il.us/exhibits/ice_ages/why_4_cool_periods.html http://www.bibliotecapleyades.net/ciencia/ciencia_iceage.htm http:// geography .howstuffworks.com/terms-and-associations/ice-age2.htm http://geography.howstuffworks.com/terms-and-associations/ice-age.htm http://www.sentex.net/~tcc / iceage.html https://www.google.com/search?q=glaciation+definition&oq=glaciation+definition&aqs=chrome..69i57.4046j0j1&sourceid=chrome&espv=210&es_sm=122&ie=UTF-8#q=glaciers+definition http: / /www.isgs.uiuc.edu/?q=outreach/geology-resources/end-moraines-end-glacial-ridehttp://www.isgs.uiuc.edu/?q=outreach/geology-resources/end-moraines -end-glacial-ride http://dictionary.reference.com/browse/glacial+drift
