Answer:

Actually, scientists do not use satellites to map the sea floor. It is done using an echo sounder on ships.

Explanation:

To map the sea floor ships are equipped with an echo sounder and a receiver. The sound beams hit the sea floor and return back to the ship and recorded in the receiver where the information is mapped to a GPS and sent back to scientists.
