How Greenhouse Effect Happen

       The greenhouse effect is a phenomenon when gases allow sunlight to enter Earth’s atmosphere but make it difficult to escape.

Greenhouse effect happen when greenhouse gases such as carbon dioxide(co2), methane, nitrous oxide, fluorinated gases, and ozone trapped Sun’s heat and make the Earth warm. But, when those gases are not in a normal amount, the heat won’t escape from Earth surface easily and makes Earth hotter. One of gases which makes the greenhouse effect is cloro-fluoro-carbon (CFC). Nowadays, the use of stuffs which are causing such fluorinated gases increase wildly. Humans use the fossil fuels, refrigerators, and air-conditioner which are some of the biggest contributor of CFC. The next gas which is also contributing in the greenhouse is carbon dioxide (CO2). Human activities, which are done by human and makes the CO2 gas in higher level, are using fossil fuel and cutting down forests. Those activities can make Earth surface warmer because of too much carbon dioxide on the atmosphere.

The processes of greenhouse effect are as follows. First, the solar radiation reached the Earth’s atmosphere and some of this is reflected back into space. Then, the rest of the sun’s energy is absorbed by the land and the oceans and makes the Earth heat. After that, heat radiates from Earth towards space. But because of the greenhouse gases, some of this heat is trapped in the atmosphere, keeping the Earth warm enough to human’s life. But, humans activities such as burning fossil fuels, cut down forests, and using stuffs which are can make CFC gases, make the amount of greenhouse gases increase in the atmosphere. Those gases are trapping extra heat and increasing Earth’s temperature. This greenhouse effect can make global warming and climate change.
