Question

The low point of the Tonga Trench, in the Pacific Ocean, is -10,630 meters. The low point of the Mariana Trench, also in the Pacific Ocean, is 890 meters lower. What is the depth of the Mariana Trench?

Answer 1

We subtract 890 from -10,630.
So, we get the following
-10,630 - 890 = -11,520

Hence, the depth of the Mariana Trench is 11,520 meters, and the lowest point in the Trench is -11,520 meters
