Decay of radioactive elements in the mantle heats it.
the earths mantle is very hot were cornstarch is not hot at all

The flow of hot rock in earths mantle will stop and Earth's magnetic field will disappear
the average temperature for the Earth's lower mantle is 5400 degrees
It is the Mantle.
The mantle is 82% of Earth's volume. It is composed of ultramafic rock called peridotite, which is hot enough to flow.
Hot, slowly flowing rock comprises the asthenosphere, which is part of the mantle.
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.
The upper layer of the Earth of how I'd describe is It's hot and is 1000 degrees
A hot spot is formed on a point of the earths surface where strong upward convection currents or plumes of hot magma in the upper mantle push up below the plates of the lithosphere causing volcanic activity. no it doesn'twhen the mantle is weak
