Description

Bathymetric Evidence for Seafloor Spreading

The ocean floor is not flat it has mountains, valleys, and ridges that provide clues about how Earth’s surface changes. Bathymetry is the study of the ocean floor’s depth and shape. Scientists have used sonar and satellite imaging to map the ocean floor, revealing mid-ocean ridge...

Transcript

Scientists expected the ocean floor to be flat, but echo sounders revealed towering underwater mountains and deep valleys.

Echo sounders send sound waves to the ocean floor, which then bounce back to the ship, ...
