Solution

The most detailed information about the topography of a large area on the ocean floor can be obtained through sonar. Here's why:

A. Sonar: Sonar systems send out sound waves that bounce off the ocean floor and return to the surface. By measuring the time it takes for the sound waves to return, scientists can determine the depth of the water and create detailed maps of the ocean floor. This method is capable of covering large areas and providing detailed information about the topography.

B. Submersibles: While submersibles can provide very detailed information, they are limited by their size and the fact that they can only cover a small area at a time. Therefore, they are not the most efficient method for mapping large areas of the ocean floor.

C. Satellite Imagery: Satellite imagery can cover large areas, but it does not provide the same level of detail as sonar. Satellites measure the surface of the ocean, and while they can detect large underwater features, they cannot provide detailed topographic maps.

D. Teams of Scuba Divers: Scuba divers can only cover a very small area and cannot dive to the depths necessary to map the majority of the ocean floor. Therefore, while they can provide detailed information, they are not suitable for mapping large areas.

So, the answer is A. Sonar.

Extremely detailed maps of the Moon and Mars have been in circulation for decades. As a result, University of Miami professor Ved Chirayath was surprised to find out that about ninety percent of Earth’s seafloor, which is significantly closer, was unexplored. He’s now determined to create complex maps showing the bottom of the oceans in high resolution. However, Chirayath had to develop new tools such as specialized digital cameras and lights to help in the project because _____
