(a) What fraction of Earth’s diameter is the greatest ocean depth? (b) The greatest mountain height?

Problem 34PE

Solution 34 PE

Step 1 of 4 :

In this question, we need to find the ratio of earth’s diameter to greatest ocean depth and the greatest mountain height

Step 2 of 4 :

We have diameter of earth as

Greatest depth

Greatest height

We have ratio of depth and diameter as

Substituting values we get

Hence the greatest depth is times the diameter of earth

Hence the ratio is
