A stick falls into a river and is carried downstream and finally sinks to the bottom of the lake. The branch becomes buried in sediment and after millions of years, a mold and cast fossil is formed. Weathering and erosion eventually bring the fossil to the surface and geologists discover it. What can the geologists learn from the fossil?
A. the relative age of the fossil
B. Changes in the environmental conditions of the area.
C. Evidence of the type of plants that once grew in the area.
