Question

Which one of the following choices best indicates the trends that take place when moving from the surface toward the center of Earth?

            a. It becomes hotter with greater pressure, but the minerals are less dense.

            b. It becomes hotter with lower pressure and the minerals are denser.

            c. It becomes cooler with lower mineral density but with greater pressure

            d. It becomes hotter with greater mineral density and greater pressure

            e. None of the above.

Explanation / Answer

d. It becomes hotter with greater mineral density and greater pressure

Earth's core is much hotter than its surface and the gravity is less, so the pressure will be more.

Also, when we move towards the core, we get heavier elements with high density.
