Answer:
Marine fossils found on landmasses.
Explanation:
Earth is an active planet, with tectonic plates that constantly move across the surface and cause changes in the distribution of physical features. The changes, in a most basic manner, can be seen in the creation of new continental masses and new ocean basins, and the destruction of continental masses and ocean basins.
The oceans we see at present have not been around forever, but they formed where plates have started to separate, while in meantime the preexisting oceans have suffered decline and eventual destruction because of it. An excellent example of where there were oceans in the past are the marine fossils. In many parts of the world that now are part of the continents, there is a huge number of marine fossils, even on mountain ranges like the Himalayas and Andes. This proves that in the past, these landmasses were part of an ocean, but because of uplift they have risen up and became part of the landmasses.
