Question

state the cause of increase of greenhouse effect

Answer 1

Before we dig deep into the causes of greenhouse effect, it is important for us to know what is greenhouse effect. You must have heard of greenhouse effect during any debate on global warming. The light that we get from the sun helps to keep this planet warm. Of the 100% light that sun sends to earth, almost 30% sunlight is reflected back into the space by clouds, ice, snow, sand and other reflective surfaces, according to NASA. Only about 70% of the sunlight is absorbed by the oceans, the land and the atmosphere. The sunlight that falls on the Earth’s surface is used for different purposes. It can be used to produce solar energy, drying clothes, or by plants in the process of photosynthesis.

The Earth’s surface warms up during the day and cools down at night, releasing the heat in the form of infrared radiation IR out of the atmosphere into space. But before all these infrared radiation can escape out of the atmosphere into the space, they are absorbed by greenhouse gases (GHG’s)present in the atmosphere. The absorption of these radiations by greenhouse gases makes it possible to keep this planet warm for humans. Without Greenhouse effect, the temperature of this planet would be lesser by 30 degree Celsius and this would be too cold for us to survive.

Answer 2

hey there....

here is ur answer!


<> green house gas effect has many adverse effect on our only plant Earth. The main gases for this green house effect are carbon-di-oxide(CO2) and sulphur dioxide (SO2)

<> now, where does these gases come from in a better way where are these gases being produced or emerging from?

<> As we know carbon-di-oxide comes from the smoke emerged by the vehicles or auto mobiles. auto mobiles also release carbonmonoxide which easily gets mixed with the haemoglobin and cause many diseases in the body.

<> Now, SO2 ( sulphur dioxide ) gets released from the fires. by fires I meant if we burn something . this is different from the burning in auto mobiles. in cars it is to produce energy but SO2 is released for like example if we burn woods or there is a forest fire.

<> The effects of green house gases caused by these two gases are.

< polar ice caps are being melted and there will be no natural habitat for the animals living in cold regions .

< The temperature of the Earth is increasing day by day. (global warming)

< The ozone layer is having holes and depleting day by day.

<> so hence, we can say that the global warming or the green house gases which cause global warming is caused by the gases like CO2 and SO2 which are released from automobiles and the burning of substances.


hope this helps!
