The most recent Ice Age
most recent ice age
It carved the mountains and valleys and rivers and many lakes. The ice made most of the topography that exists today. Erosion gradually lessens the effect of the ice carving the land. It also killed most of the life here.
Technically we are still in a Ice age. As the definition of a ice age is "a time when a part of the planet is cover in permanent ice". Now we have perma-frost in the Arctic/Antarctic and ice covers our highest mountains all year round.There is less ice every year however.This is due to global warming.Due to this the oceans rise and grow colder.Never the less this still means we are still in the latest Ice age.
