What can rocks tell us?
Sedimentary rocks tell us about past environments at Earth’s surface. Because of this, they are the primary story-tellers of past climate, life, and major events at Earth’s surface. Each type of environment has particular processes that occur in it that cause a particular type of sediment to be deposited there.
