How does the mantle affect earth's crust?

Convection currents in the mantle create plate tectonics.

How hot is the earth's mantle?

In the mantle, temperatures range between 500 to 900 °C (932 to 1,652 °F) at the upper boundary with the crust; to over 4,000 °C (7,230 °F) near the boundary with the cor

Is the Earth's mantle liquid?

No. While much of the mantle is hot enough that the rock would melt  if exposed to the surface, the enormous pressure keeps in a state  that is technically considered solid.

Are plates in the Earth's mantle or earth's surface?
