Heat Transference Educational Facts Children's Science Book

Conduction is the second most common form of heat transfer.

Unlike convection, this is a process that occurs in a sealed path.

It is carried out by the collision of molecules. Finally, radiation is the last form of heat transfer.

Unlike convection and conduction, radiation does not rely on the medium to carry it.

Radiation comes from the Sun. When the Sun emits light energy, it heats up the Earth.

This heat is then absorbed by the Earth.
