Gwendolen · Answer 1

(C) increases exponentially as you go deeper into the Earth.

Explanation:

Geothermal gradient is the amount that the Earth's temperature increases with depth. It indicates heat flowing from Earth's warm interior to its surface. Temperature within the Earth increases with depth, this is due to the high viscous or partially molten rock found at the margins of the tectonic plates.
