of prehistoric climates from evidence preserved in a wide range of geological settings. Paleoclimatologists study the evidence preserved in these geological settings‚ and search for the reasons behind climatic change throughout Earth’s history. By doing this‚ scientists may better predict future climate change and calculate the impact of humankind’s activities on the atmosphere and climate. Paleoclimatologists must piece together climatic history‚ but the further they look into the past‚ the more

As geologists‚ we examine layers of sediment on the Earth’s surface to approximate the dates of past geologic time periods. Ah sediment as you know is material like sand‚ gravel‚ fossil fragments that is transported by natural processes like wind ‚ water flow or the movement of glaciers. So sediment is transported and then deposited and it forms layers on the Earth’s surface over time. We examine these layers to learn about different geologic time periods including when they began and ended. For
