How do we know there is heat inside the earth
WebNov 27, 2024 · The world we know lies on tectonic plates making up Earth’s crust, which varies in thickness from three miles to over 40. 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.
