If fossils of a water animal or plant are found in a place then that place used to be covered by water in the past, and generally, mountains are good places to find fossils. Given these facts, a prehistoric shark tooth found discovered high in the mountains likely indicates what among the following options:
- The area was once underwater
 - Currents were once more severe
 - Sharks swim long distances
 - tectonic plates being pushed together
 - the wearing away of rock
 - Sharks are remarkable at adaptation
 - movement of tectonic plates
 - movements in the earth's crust
