The earth's carbon and water cycles support a natural greenhouse effect in the atmosphere where just enough of the sun's heat is kept back so that life can go on comfortably. This is how the greenhouse effect helps us.

But the greenhouse effect is now turning into an "enhanced" or accelerated greenhouse effect. This is causing global warming and is not helping us.

Two hundred years ago we started digging up and burning fossil fuels (for industry, transport and to make electricity). Burning fossil fuels like coal, oil and natural gas releases all the carbon dioxide that had been hidden underground for millions of years. We also cut down the great forests of the earth, which can take carbon dioxide out of the atmosphere.

These two things, burning fossil fuels and deforestation are disrupting the normal greenhouse effect, which is now becoming an enhanced greenhouse effect, caused by man.

A:The sun sends light rays into the earth, but most of the light that hits the earth is reflected back into space. If carbon dioxide, along with water vapor, methane, sulfur hexafluoride, nitrous oxide, several types of chlorinated fluorocarbons and a few other gases, did not trap much of the reflected light, the earth would be so cold that no life could exist upon its surface. The trapping of the reflected light by gases is called the greenhouse effect.

How does the ozone layer help in protecting the earth from greenhouse effect?

Ozone layer does not allow UV to pass through which kill the greenhouse gas absorbing plankton. This avoids the greenhouse effect.

What is the beautiful effect of the greenhouse effect?

The beautiful effect of the greenhouse effect is that it keeps us warm. The natural greenhouse effect is supported by the water and carbon cycles moving water and carbon in and out of the atmosphere, in balance. Without this natural effect the earth would be much colder, probably frozen, and we couldn't survive.


What is a sentence with greenhouse effect?

The greenhouse effect is the natural way that the Earth keeps warm. Too many extra greenhouse gases turn the greenhouse effect into an enhanced greenhouse effect. The enhanced, or accelerated, greenhouse effect is causing global warming.


Why do you think greenhouse gases get that nickname?

Greenhouse gases get their nickname because, like the glass walls of a greenhouse, they allow sunlight to enter and warm the Earth's surface. However, they also trap some of the heat energy from the sun, leading to an overall warming effect known as the greenhouse effect.


How do you use The greenhouse effect in a sentence?

the greenhouse effect is a global phenomenon.
