The greenhouse effect . . .

The greenhouse effect is when the temperature of the atmosphere raises because certain gases trap energy from the sun. The greenhouse effect is important.

Without the greenhouse effect, the Earth would not be warm enough for humans to live, but the may cause problems for humans, plants, and animals if is much warmed.

Sunlight enters the Earth's atmosphere, passing through the certain gases and even reach the surface the Earth's, water and biosphere absorb the sunlight’s energy.

And when is absorbed the energy is sent back into the atmosphere. Their gases are: (water vapor, carbon dioxide, nitrous oxide, and methane)

Most greenhouses look like a small glass house. Greenhouses are used to grow plants, especially in the winter. Greenhouses work by trapping heat from the sun.

The glass panels let in light and from escaping. This causes the greenhouse to heat up,

and keeps the plants warm enough to live in the winter.
