what is greenhouse effect?

Answer 1

THE GREENHOUSE EFFECT
Our atmosphere acts like a blanket trapping heat and keeping Earth at a habitable temperature, it’s this retaining of heat that is referred to as the Greenhouse Effect. The greenhouse effect is caused by greenhouse gases that trap heat from the sun, the more greenhouse gases there are the more heat is retained

HOW IT WORKS
The heat from the sun (solar radiation) has a very short wavelength and this can pass easily through the layer of greenhouse gases. The heat from the earth (thermal radiation) has a longer wavelength and some of this becomes trapped by the layer of greenhouse gases. The more GHG's are in the atmosphere the more heat is trapped.

GREENHOUSE GASES
Water vapour (H20) is the most prevalent greenhouse gas and occurs naturally. Some greenhouse gases are both natural and manmade including carbon dioxide (CO2), methane (CH4), nitrous oxide (NO) and tetraflouromethane (CF4). There are several synthetic gases consisting of carbon and halogens, many of the manmade greenhouse gases are also responsible for ozone depletion.

As with temperature, there is a natural cycle in the amount of CO2 in the atmosphere. Ice core samples extending back some 650,000 years show the minimum amount of atmospheric CO2 to have been around 190 parts per million by volume (ppmv) and the maximum about 300 ppmv. The worry is that the current levels of CO2 are considerably higher at around 385 ppmv .

Answer 2

The greenhouse effect is when radiant energy from the sun comes down to the earth, is turned into ultraviolet energy by the plants, and gets obsorbed by carbon dioxide, which multiplies because of people who burn houses and people who don't have hybrid cars and slowly ruins the Ozone layer, which leads to global warming. In other words, it;s a bad thing, and if you burn houses and don't have a hybrid car, that's a complete and total no-no! (Sorry, I am obsessed with keeping our planet safe and happy! <;)))))
