In this performance task, you will answer five questions.
A family goes camping on a mountain. The family returns to a spot that the family has visited before. They are surprised to see that the area looks different now.
Heavy rains have washed away some soil and exposed a large fossil embedded in rock.
What two systems contributed most to exposing the fossil? Select the correct systems from the menus to complete this statement.
The fossil was exposed by an interaction between the and the .
The scientists want to find another fossil that formed at a similar place and time as the whale fossil. The scientists eventually find a rock with more fossils. The rock has two distinct layers. This diagram shows the layers and their fossils. Assume the rock layers are nearly horizontal.
Identify which one of the two rock layers is older, and explain what change in the landscape must have occurred between the formation of the two layers.
