Question

question 5 which of the following statements about continental drift is true? because of continental drift, the majority of most continents’ landmass remains underwater, which has severely limited biodiversity. about 100 million years ago, all of the continents were one giant landmass called pangaea. all of the continents were once one big supercontinent, but their separation created more coastline, which was beneficial for biodiversity. after the continents were separated, continental drift slowed, until it has become almost nonexistent today.

Explanation:

Continental drift theory posits that all continents were once part of a super - continent called Pangaea. As the continents separated, more coastline was created, which provided more diverse habitats and was beneficial for biodiversity. The majority of continents' landmass is not underwater due to continental drift. Pangaea existed about 300 million years ago, not 100 million years ago. Continental drift is still ongoing today.

Answer:

C. All of the continents were once one big supercontinent, but their separation created more coastline, which was beneficial for biodiversity.
