Question

How do scientists study the seafloor?

Answer 1

Hint: It is possible to use SONAR to determine how deep the ocean is the time it takes sound waves to travel from the surface to the oceans floor and the back again is measured by this device called as SONAR sound wave travel at a known velocity through the water once the scientist are aware of the wave’s travel time they can measure the distance to the bottom of the ocean.

Complete answer:
Scientists used the SONAR method to study the seafloor.
It is basically the concept of echo which is simply described as the sound that bounced of off a surface and came back to us.
SONAR is using the method to study the bottom of the ocean.
The full form the SONAR is sound navigation and ranging.
Echo ranging is also called the SONAR method; it is the system that calculates and measures the distance position and the velocity of the objects underwater by using ultrasonic wave.
SONAR uses echoes to determine the sea depth and locating the presence of the objects underwater.

Additional information:
There are two types of SONAR.
Active SONAR: The SONAR transmits an acoustic signal into the water and gets bounced back if there is an object on the way to the signal and returns a echo to the SONAR transducer the SONAR tests signal power the time taken by the signal emitted and its absorption is the object’s orientation and range.
Passive SONAR: This SONAR is used to track noise from underwater objects such as submarines and the whales as well as other marine animals passive SONAR instead of listening to the signals that travel towards it does not emit its own signal.

Note:
As an approach to how scientists study the sea we have seen the working principle of SONAR(sound navigation and ranging) which used the principle of echo to know objects at the bottom of the ocean.
