Question

Which is NOT true of a bathymetric map? a. it is a type of topographic map b. larger numbers show great depths c. negative numbers are used to show depths below sea level d. it is often made using sonar.

Answer 1

Bathymetric maps use negative numbers to indicate depths below sea level, and large numbers do not show greater depths; sonar is often used to create these maps.

Step-by-step explanation:

A bathymetric map is a specific type of topographic map that details the three-dimensional contour of the ocean floor, rather than the land. One aspect that is NOT true of a bathymetric map is that larger numbers show greater depths; instead, they typically use negative numbers to indicate depths below sea level.

Sonar technology is often employed in the creation of bathymetric maps because it can transmit sound waves to bounce off the seabed and measure the depths of the ocean.

Thus, sonar is suitable for locating large objects such as ships or plane wreckage, but may not resolve smaller objects or detailed shapes effectively. Bathymetric maps, just like topographic maps, show the shape of the Earth's surface and are useful for a variety of applications, including geological studies and navigation.
