Abstract
The Earth has experienced a lot of changes over its history. 650 million years ago an event called snowball earth is hypothesized to have occurred. Evidence has been found that suggests the earth had once been completely glaciated at one point, but there is also contrary evidence that suggests that this event did not happen. There are many pieces of evidence that support the hypothesis that snowball earth did occur as well as other evidence that may need to be found first in order to draw a better conclusion and confirm the occurrence of snowball earth. Some evidence that would help settle the debate includes temperature and depositions records through carbon dating ice cores. In this presentation we will look at the physical, chemical, biological, and conceptual evidence of that supports the hypothesis of snowball earth. We will also look at counter evidence that does not support the snowball earth hypothesis.
