Question

Which best explains mantel convection

Answer 1

Answer:

The heat given off by Earth's core is circulated through mantle convection.

Explanation:

Heating materials usually causes them to expand; as they become hotter, they also become less dense. Convection describes the transfer of heat from hot areas of liquids and gases to cooler ones. This causes the heated, less dense material to rise and more dense material to fall, as it’s pulled by gravity. Super-heated metal forming Earth’s central core heats rock in the mantle; the hot and cool rock slowly rise and sink- this circulation process is called mantle convection.
