Which of the following would be most useful in determining the structure of sediments on the ocean floor? a. sonar b. seismic profiling c. satellite imaging d. echo sounding

The correct answer is Sonar.

Sonar is used to determine the structure of the sediments found on the ocean floor.This technique uses sound waves to determine the distance from the ocean sea surface to the sea floor.

Over the last few decades scientists have evolved many types of sonar that can now be used to determine the structures of the sea floor and even they can also tell us the currents and life forms present in ocean.
