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?
Step-by-step explanation:All you have to do is subtract 11.033 from 8.065 which gives you 2.968.And since the first number is higher than the second number, the change is positive.
