Select the correct answer.
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
A. 19.098 kilometers
To find the net change in elevation from the Atacama trench to the Mariana trench, we need to subtract the elevation of the Atacama trench from the elevation of the Mariana trench.
-11.033 kilometers - (-8.065 kilometers)
= -11.033 kilometers + 8.065 kilometers
= -2.968 kilometers
So, the net change in elevation from the Atacama trench to the Mariana trench is -2.968 kilometers.
Therefore, the correct answer is C. -2.968 kilometers.
