Answer 1

The ocean floor is the land beneath the ocean. It has diverse landforms ranging from the continental shelf to trenches and mountains. Continental shelves are resource-rich regions. They are rich fishing grounds due to the presence of adequate sunlight and plankton.

The study of the ocean floor is useful for deep sea research. For instance, by determining the age of rocks, scientists have developed plate tectonics theory which explains the formation of various landforms like mountains, trenches, and activities like volcanoes and earthquake.
