How can plate tectonics help explain the existence of fossil marine organisms in rocks found on top of compressional mountains?
What will be an ideal response?
Answer: When two landmasses collide, rocks that are located between them will get compressed. The result is shortening and thickening of the crust, forcing the rocks upward. If the rocks in question happen to be a fossiliferous limestone from a shallow marine shelf, then the rocks at the top of the mountains would be those that formed in the sea.
