Greenhouse Effect

To view these resources with no ads please Login or Subscribe (and help support our site).

Sunlight (solar radiation) provides the energy and warmth that allows life on Earth. Yet, only about half the sunlight that reaches Earth gets through the atmosphere to the surface of the planet. That sunlight is absorbed by the oceans and land and then radiated back upward as heat. About 90% of this heat is absorbed by the greenhouse gasses in the atmosphere – water vapor, carbon dioxide, methane, nitrous oxide and oxygen. They then radiate the heat back to Earth which keeps the planet in a temperature range that supports life. This natural greenhouse effect is why life was able to develop on Earth.
