Question

1pt which of the following can sonar be used for?

a. calculating the depth of the ocean floor

b. calculating the density of biomass in ocean water

c. measuring the pressure gradient of ocean water

d. measuring the temperature gradient of ocean water

Explanation:

Sonar (Sound Navigation and Ranging) works by emitting sound waves and measuring the time it takes for the echoes to return. This is used to calculate distances, such as the depth of the ocean floor. It is not used for calculating biomass density, pressure gradient, or temperature gradient of ocean water.

Answer:

A. calculating the depth of the ocean floor
