Question 29 2 pts Greenhouse gases are known to raise air temperatures by... creating heat through chemical reactions with atmospheric pollutants trapping high energy molecules and atomic particles absorbing incoming visible light from the sun absorbing and trapping infrared radiation

Transcript

00:01 High students in this question we have to select the appropriate mechanism by which greenhouse gases which is represented as g .s .g leads to global warming.

00:11 Now before discussing about global warming, we need to know what is this greenhouse effect.

00:17 We know that sun is the ultimate source of energy from which radiation are being emitted.

00:22 Now most of these radiation will pass through the earth's atmosphere while some of them will get escape back to the space.

00:30 Now those radiations which penetrate through the earth's atmosphere will reach the earth's surface from where they will be reflected back at ir radiation.

00:40 Now these ir radiations which are being emitted by the surface will reach back to the atmosphere from which some of them will again escape back to the space while most of the ir radiations will get absorbed and re -radiated in all directions by the greenhouse gases present in the atmosphere.

00:59 Now this greenhouse gases include carbon dioxide, methane, nitric oxide, water vapor, etc.

01:09 Now this reflection of ir radiation back to the earth surface leads to an increase in the temperature of the earth and this eventually warms up the earth and this process is known as the greenhouse effect.

01:24 But when the amount of these greenhouse gases increase in the moisture, it leads to an increase in the average value of temperature of the earth.

01:37 And this increase in average value of temperature of the earth due to the increased effect of greenhouse effects, which is known as the global farming.

01:47 Now, in this question, four options are being given from which we have to select the appropriate method by which greenhouse gases leads to global warming.

01:57 And the options provided here include reflection of solar radiation, absorption of atmosphere reporter, absorption and re -radiation of long wave energy and finally it causes the phato spheres to catch fire...
