Greenhouse effect - Wikipedia
The greenhouse effect is the process by which radiation from a planet's atmosphere warms the planet's surface to a temperature above what it would be without its atmosphere. If a planet's atmosphere contains radiatively active gases (i.e., greenhouse gases) they will radiate energy in all directions.

What is the Greenhouse Effect? | Global Warming
The greenhouse effect, combined with increasing levels of greenhouse gases and the resulting global warming, is expected to have profound implications, according to the near-universal consensus of ...

greenhouse effect | Definition, Diagram, Causes, & Facts ...
Greenhouse effect, a warming of Earth’s surface and troposphere (the lowest layer of the atmosphere) caused by the presence of water vapour, carbon dioxide, methane, and certain other gases in the air.Of those gases, known as greenhouse gases, water vapour has the largest effect.

NASA Climate Kids :: What is the greenhouse effect?
A greenhouse is a house made of glass. It has glass walls and a glass roof. People grow tomatoes and flowers and other plants in them. A greenhouse stays warm inside, even during winter.

The Greenhouse Effect
Greenhouse Effect The greenhouse effect refers to circumstances where the short wavelengths of visible light from the sun pass through a transparent medium and are absorbed, but the longer wavelengths of the infrared re-radiation from the heated objects are unable to pass through that medium.

The Greenhouse Effect | UCAR Center for Science Education
The Greenhouse Effect Energy from the Sun that makes its way to Earth can have trouble finding its way back out to space. The greenhouse effect causes some of this energy to be waylaid in the atmosphere, absorbed and released by greenhouse gases.

greenhouse effect | National Geographic Society
The greenhouse effect happens when certain gases—known as greenhouse gases—collect in Earth’s atmosphere.These gases include carbon dioxide (CO 2), methane, nitrous oxide (N 2 O), fluorinated gases, and ozone. Greenhouse gases let the sun’s light shine onto the Earth’s surface, but they trap the heat that reflects back up into the atmosphere.

Greenhouse effect | Department of the Environment and Energy
The greenhouse effect is a natural process that warms the Earth’s surface. When the Sun’s energy reaches the Earth’s atmosphere, some of it is reflected back to space and the rest is absorbed and re-radiated by greenhouse gases.
