Is a region where convection currents occur within earth.
a. the crust
b. the inner core
c. the lower mantle
d. the asthenosphere

The correct answer is option c. the lower mantle.

Explanation:

The process in which a movement of energy goes from one place to another is called convection current, or heat transfer by convection.

This movement is caused by convection currents that move heat from the deepest of the earth, to the earth's surface and it only transport liquids and gases, as they can move freely.

This whole process occurs inside the lower mantle of the earth's surface, which facilitates its fluidity.

The hot material found in the deepest part of the mantle comes out and cools. Then it sinks and does it again and again.

Therefore, this process is a continuous heating of liquids or gases by convection.
