What heats lava? Lava is hot for two primary reasons: Pressure and radiogenic heating make it very hot deep in the Earth (about 100 km down) where rocks melt to make magma. The rock around the magma is a good insulator so the magma doesn’t lose much heat on the way to the surface.
How does lava stay hot? The initial contact between a lava flow, the air above it, and ground surface below it, quickly hardens the outer crust (top and bottom) of the flow. … As the crust cools and thickens, it retains heat within the flow’s interior.
