If scientists found drastic changes in the types of sediment found in different rock layers, the most plausible conclusion they might draw is the area went through major changes in climate over geologic time. This conclusion is supported by the fact that different types of sediments can form under varying environmental conditions, such as changes in climate, water availability, and sediment supply. Such changes often indicate shifts in the geologic and climatic history of an area.
What conclusion might scientists draw if they found drastic changes in the types of sediment found in different rock layers?
the rock layers in that area were not exposed to normal weather
the rock layers in that area formed slower than surrounding areas
the area went through major changes in climate over geologic time
the area was likely under water for long periods of time
