the amount of spreading that occurs on the ocean floor
the amount of spreading that occurs on the ocean floor
the time it takes an underwater vehicle to reach the ocean floor
the time it takes an underwater vehicle to reach the ocean floor
the time it takes for a pulse to bounce from the ocean floor
The correct answer is: the time it takes for a pulse to bounce from the ocean floor.
The correct answer is: the time it takes for a pulse to bounce from the ocean floor.
To make a sonar map of the ocean floor, sonar technology is used. Sonar stands for Sound Navigation and Ranging. It works by emitting sound waves into the water and measuring the time it takes for the sound waves to bounce back after hitting an object. In the case of sonar mapping of the ocean floor, a device called a sonar transducer is used to send the sound waves downward.
The sound waves emitted by the sonar transducer travel through water until they reach the ocean floor. When the sound waves encounter the ocean floor, they bounce off and return to the sonar transducer. The time it takes for the sound waves to make this round trip is measured.
By analyzing the time it takes for the sound waves to bounce back, scientists can calculate the depth of the ocean at different points. This data is then used to create a sonar map of the ocean floor, which shows the topography and features of the seabed.
Therefore, the correct data used to make a sonar map of the ocean floor is the time it takes for a pulse to bounce from the ocean floor.
