Radiation<\/p>\n<p>Radiation is the transfer of energy through electromagnetic waves. The sun radiates energy to the Earth, and the Earth radiates energy back to space. On a clear, calm, cold morning, the Earth&#8217;s surface radiates energy into space more quickly than it receives energy from the sun. This causes the Earth&#8217;s surface to cool.

Latent heat is the heat that is absorbed or released when a substance changes state, such as from a liquid to a solid.<\/p>\n<p>In this case, conduction, convection, and latent heat are not the main mechanisms by which the tops of cars cool.
