Electromagnetic waves, which are from space
Infrared radiation, is the long waves
Ultraviolet radiation, is the short waves
Energy gets to Earth by electromagnetic waves. When Earth’s surface is heated, it radiates some of the energy from the sun back into the atmosphere in the form of longer wavelength radiation.
Blue and violet waves are the shortest waves and red and orange are the longest waves.
Energy from the sun is absorbed within the atmosphere. Water vapor and carbon dioxide absorb some infrared radiation. The ozone layer in the stratosphere absorbs most of the ultraviolet radiation. Clouds, dust and other gases also absorb energy from the sun.
Some of the sun’s energy reaches Earth’s surface and it is reflected back into the atmosphere. Some of the energy, however, is absorbed by the land and water and changed into heat.
If a volcano erupted it would make the sunrise and sunset more red because the particles from the volcanic ash would enter the air and add more particles which would absorb more blue and violet waves and make it redder.
The energy from the sun that is absorbed by Earth’s surface is radiated/ reflected back into the atmosphere.
The sky is blue because gas molecules scatter short wavelength of visible light.
Sunsets are red because when the sun lowers there are more gas molecules which absorb blue and violet rays making them red.
Without the green house effect which is the process by which heat is trapped in the atmosphere by water vapor, carbon dioxide, methane, and other gasses that form a blanket around the earth. Without the greenhouse effect we would be dead. We would freeze to death because there would be nothing to heat the earth.
