Why does radiation happen?

It happens because the heat is transferred through the air from something hot to something cold.

what are the differences between conduction, radiation and convection?

^{Radiation is when waves or rays travel with electromagnetic energy and go out into the cold.} 

^{Conduction is when heat energy goes through direct contact.}

^{Convection is when the transfer of heat is the movement of a fluid.}
