how is earth's atmosphere different to a greenhouse?

The greenhouse effect works much the same way on Earth. Gases in the atmosphere, such as carbon dioxide, trap heat just like the glass roof of a greenhouse. These heat-trapping gases are called greenhouse gases. ... Earth's surface warms up in the sunlight.

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.

The major greenhouse gases are water vapor, which causes about 36-70% of the greenhouse effect on Earth (not including clouds); carbon dioxide, which causes 9-26%; methane, which causes 4-9%, and ozone, which causes 3-7%.

The Earth is wrapped in a blanket of air called the 'atmosphere', which is made up of several layers of gases. The Sun is much hotter than the Earth and it gives off rays of light energy that travel through the atmosphere and reach the Earth's surface.

Earth's surface warms up in the sunlight. At night, Earth's surface cools, releasing heat back into the air. But some of the heat is trapped by the greenhouse gases in the atmosphere. That's what keeps our Earth a warm and cozy 58 degrees Fahrenheit (14 degrees Celsius), on average.

Solar energy absorbed at Earth's surface is radiated back into the atmosphere as heat. As the heat makes its way through the atmosphere and back out to space, greenhouse gases absorb much of it. ... They radiate the heat back to the Earth's surface, to another greenhouse gas molecule, or out to space.

Due to the chemical composition of the earth's atmosphere, most of the infrared radiation emitted by the warm surface never reaches space. Instead the radiation is reflected or absorbed by compounds known as greenhouse gasses. When these compounds absorb the infrared radiation from the surface, the atmosphere heats up.

The astute reader will note that the atmospheric "greenhouse" effect is really a series of absorption-emission processes rather than just heat entrapment (as a real greenhouse does). According to NASA, water vapor accounts for about 50+% of the absorption. Carbon dioxide accounts for 20%.

As nouns the difference between atmosphere and biosphere is that atmosphere is the gases surrounding the earth or any astronomical body while biosphere is the part of the earth and its atmosphere capable of supporting life.

Argon, an element found in relative abundance in the Earth's atmosphere, is not a greenhouse gas because, like oxygen, nitrogen and other gases, it is largely transparent to the wavelengths of light responsible for trapping heat.

The main differences between greenhouse gases and air pollutants are how they affect our health and the environment. ... The main problems caused by air pollution occur close to the ground, such as soiling of buildings and producing health effects, but greenhouse gases affect the whole of the atmosphere.

Greenhouse gases are gases in Earth's atmosphere that trap heat. They let sunlight pass through the atmosphere, but they prevent the heat that the sunlight brings from leaving the atmosphere. The main greenhouse gases are: Water vapor.

Greenhouse effect. Step 1: Solar radiation reaches the Earth's atmosphere - some of this is reflected back into space. Step 2: The rest of the sun's energy is absorbed by the land and the oceans, heating the Earth. Step 3: Heat radiates from Earth towards space.

The atmosphere protects life on Earth by absorbing ultraviolet solar radiation and warming the surface through heat retention (the greenhouse effect).

If not for the greenhouse effect, Earth would be an ice ball. So, CO2 and other greenhouse gases are good—up to a point. But CO2 is so good at holding in heat from the Sun, that even a small increase in CO2 in the atmosphere can cause Earth to get even warmer.
