How do we know there is heat inside the earth

WebDuring the day, sunlight heats the ground, which in turn heats the air directly above it via conduction. At night, the ground cools and the heat flows from the warmer air directly above to the cooler ground via conduction. On clear, sunny days with little or no wind, air temperature can be much higher right near the ground than slightly above it. WebPlus, from our knowledge of the abundance of elements in the Universe and how they behave, we think it’s made mainly of iron under huge amounts of pressure.
