Scientists use sonar machines in order to map the contour of the ocean floor. The data from the sonar machines make a model of the ocean floor. What information can be obtained from this model?
A.
what sort of organisms live near the ocean floor
B.
what sort of landforms are found on the ocean floor
C.
how old the ocean's crust is
D.
what temperature the water is near the ocean floor

Respuesta :

it would be B. since the scanning shows what the terrain is down there

(I listened)

Answer:

Option (B)

Explanation:

Sonar stands for Sound Navigation and Ranging. It is a machine that is technically designed to understand the bathymetry and the topography of the ocean floor. It helps in determining what kind of landforms exist on the ocean floor.

Here, in this machine, sound waves are used that propagates through the ocean water. This waves then strikes the ocean floor and are reflected back. This reflected sound takes various time at different places, to be detected by the detector. This difference in time helps them to map the surface of the ocean floor.

Thus, the correct answer is option (B).
