which supports the theory that some mountains were once at the bottom of an ocean? freshwater rivers flow to the ocean. both mountains and ocean floors have similar minerals in their rocks. there are underwater mountains on the ocean floor today. fossils of marine organisms are found on the tops of some mountains.

Answer

Brief Explanations:

Fossils of marine organisms on mountain - tops suggest that the area was once underwater. The presence of such fossils is strong evidence for the theory that some mountains were once at the bottom of an ocean. The other options do not directly support the idea that mountains were once ocean - bottom areas. Freshwater rivers flowing to the ocean is a normal hydrological process, similar minerals in mountain and ocean - floor rocks could be due to other geological reasons, and underwater mountains today are not evidence for the past state of above - water mountains.

Answer:

Fossils of marine organisms are found on the tops of some mountains.
