there are many reasons for heat in earths crust. like the friction between rock masses during movements of earths crust. there may also be heat left over from the original heat of earths interior. but the main reason for heat in earths crust is radioactive elements. they give off energy that can be absorbed as heat. some radioactive elements include uranium, thorium, and a form of potassium.
The sun is the earth's source of heat.
The heat transfer is moved to the crust. The earth's crust moves to the inner core
The major source of the earth energy is solar radiation, or more bluntly light and heat from the sun. Heat creates the differences in air masses and is responsible for most of there movement.
The sun
The Earths mantle is the viscous layer between the core and the crust. It is hot because of heat from the core, and part-liquid because it is composed of material with a moderate melting point. This mantle is the source of the volcanic material. Silica is a major component.

This heat transfer happens by convection.

by heat and pressure
It is a massive magma chamber to what has been called a supervolcano that lies beneath much of the park.
the inner core
The Earth system is powered by energy from two major sources: the Sun and the planet's internal heat.
