UV radiation is given off by the sun. UV radiation is a broad spectrum that consists of UVA, UVB and UVC radiation. The planets atmosphere protects us from harmful UVA and 90% UVB radiation, leaving unharmful UVC radiation to pass through the atmosphere. However, due to the increasing number of greenhouse gases, Ozone is being broken down a lot faster than it should, which in turn means that more harmful UV radiation can come through, which means that we are at a higher risk of cancer.
Ultra-violet radiation from the sun is caused by the high temperature of the sun, which in turn is the result of nuclear fusion. High temperatures cause sub-atomic particles to vibrate rapidly, and vibrating electrons give off electromagnetic radiation. The faster the electrons vibrate, the higher the frequency, and the higher the energy content of the radiation that they radiate.

Infrared radiation is the form of radiation given off by the Earth that causes heating of the Earth's atmosphere. This radiation is absorbed by greenhouse gases in the atmosphere, which traps heat and warms the planet.
