What is GreenHouse Effect?

The greenhouse effect is the rise in temperature that the Earth experiences because certain gases in the atmosphere (water vapor, carbon dioxide, nitrous oxide, and methane, for example) trap energy from the sun. If these gases don't trap energy from the sun, than the temperature of the earth would average to some 60ºF colder. Because how they warm our planet these gases are called as greenhouse gases and the effect they create in the atmosphere is called as Greenhouse Effect.

What causes GreenHouse Effect?

Earth receives most of it's energy from called radiation from sun. The incoming solar energy has a very short wavelength and passes through the atmospheric gases unaffected to reach the earth's surface. About 30 percent of the sunlight that beams toward Earth is deflected by the outer atmosphere and scattered back into space. The rest reaches the planet’s surface and is reflected upward again as a type of slow-moving energy called infrared radiation. The earth's surface absorbs the solar energy and releases it back to the atmosphere as Infrared radiation, some of which goes back into the space. Now some of the IR radiation emitted by the earth is absorbed by the gases such as water vapor, carbon dioxide and methane, in the atmosphere that re-emit the energy as heat back toward the earth's surface and slows its escape from the atmosphere causes the warming known as the Greenhouse effect.

Why Greenhouse effect is important?

Greenhouse effect is important for existence of life on the earth's surface. Most of the greenhoses looks like the small green houses used to grow plants in winter and colder regions. Greenhouse works by tapping heat from the sun. The greenhouse let in light but doesn't allow heat from escaping thus making it possible to grow plants in farmost colder regions. The same type of greenhouse effect takes place in the car when you park under the sunlight. The greenhouse effect is important. Without the greenhouse effect, the Earth would not be warm enough for humans to live. But if the greenhouse effect becomes stronger, it could make the Earth warmer than usual. Even a little extra warming may cause problems for humans, plants, and animals.
