the diagram shows an area where fossils were discovered in different rock layers. which sequence best represents how the environment in this area changed over time? a ocean - dry land - ocean b dry land - ocean - dry land c dry land - ocean d ocean - dry land

Answer

Brief Explanations:

Fossils in layer A (fish) suggest an ocean - environment. Fossils in layer D (scorpion) suggest a dry - land environment. Layers in between also show a mix of marine and non - marine fossils, indicating a transition. So the environment changed from ocean to dry land.
