Which data is used to make a sonar map of the ocean floor? (1 point)

Question

• the amount of spreading that occurs on the ocean floor
• the amount of light that reaches the ocean floor
• the time it takes an underwater vehicle to reach the ocean floor
• the time it takes for a pulse to bounce from the ocean floor…

Answer 1

The correct option for making a sonar map of the ocean floor is:

• the time it takes for a pulse to bounce from the ocean floor.

This method involves sending sound waves from a vessel to the ocean floor and measuring the time it takes for the echo to return, which helps in determining the depth and topography of the ocean floor.
