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.
Heat transfer in the Earth's mantle drives the movement of the Earth's crust through the process of convection. As mantle material heats up, it becomes less dense and rises, causing the overlying crust to move. At the same time, cooler mantle material sinks back down, completing the cycle of heat transfer and driving the continuous motion of tectonic plates.
The heat from below Earth's surface is called geothermal energy. This energy originates from the natural decay of radioactive isotopes in the Earth's crust and mantle, creating heat that can be harnessed for various applications such as electricity generation and heating.
The temperature of the Earth's layers increases from the crust towards the core. The outermost layer, the crust, has the lowest temperature, while the inner core has the highest temperature. This gradient is due to the heat generated by radioactive decay in the core and the residual heat from the Earth's formation.
Geothermal heat reaches the Earth's surface through conduction, which involves the slow transfer of heat through the Earth's crust, and through convection, where hot molten rock rises towards the surface, bringing heat along with it.

Sedimentary rocks get transformed into metamorphic and eventually igneous rocks in deep earth's crust.

No.
Heat transfer in the Earth's mantle drives the movement of the Earth's crust through the process of convection. As mantle material heats up, it becomes less dense and rises, causing the overlying crust to move. At the same time, cooler mantle material sinks back down, completing the cycle of heat transfer and driving the continuous motion of tectonic plates.
Mantle plumes are in the mantle, BELOW the Earth's crust. The circulation of heat from the lower mantle to the upper mantle can cause "hot spots" in the overlying crust, heating the magma in the areas.
A magma chamber.

Most convection currents exist in the mantle, the layer below the Earth's crust. As the semi-molten rock heats up, it rises closer to the surface, and it sinks as it cools. This is how plate tectonics works, as the crust's plates move on these currents.
Many elements and materials which could not have been produced any other way (like diamonds).
I would call this convection currents in the mantle.
