Question

The deepest part of the Mariana trench (the deepest trench in the world’s oceans) is at an elevation of -11.033 kilometers. The elevation of the deepest part of the Atacama trench is -8.065 kilometers. What is the net change in elevation from the Atacama trench to the Mariana trench?

A.
19.098 kilometers
B.
2.968 kilometers
C.
-2.968 kilometers
D.
-19.098 kilometers

Answer 1

option C.

Explanation:

To calculate the net change in elevation from the Atacama trench to the Mariana trench, we subtract the elevation of the Atacama trench from the elevation of the Mariana trench.Net change in elevation = Elevation of Mariana trench - Elevation of Atacama trench

= (-11.033 kilometers) - (-8.065 kilometers)

= -11.033 kilometers + 8.065 kilometers

= -2.968 kilometersTherefore, the net change in elevation from the Atacama trench to the Mariana trench is -2.968 kilometers. This corresponds to option C.
