Strata and Fossils

The fossils of clams, which live at the seashore, were found in a rock layer directly below a rock layer that contained tree fossils. This evidence can be used to support the idea that -

• fossils form more quickly at the seashore than other places.

• clams and trees are always found in the same area.

• the area where the fossils were found changed over time.

• the layer containing the trees is older than the clam layer.
