Answer 1

21. There are for different layers of the atmosphere which contains different amount of the gases which are involved in the protection of the Earth. In the case of stratosphere the ozone presence can be found and that is useful for the absorption of the UV radiations which are harmful for the human health or the Earth. Hence, the gases which are present in this layer will not be able to cause the green house effect. Thus, the layer which is near to the Earth surface which is the troposphere will allow this gases to be present and thus this affects the Earth's surface in the adverse manner. Thus, the answer to this question is "a"

22. The greenhouse gases involves the presence of the carbon dioxide which liberates through the process of combustion which ultimately comes from the burning of the fossil fuels. Hence, the answer to this question is "b"

23. Whenever the chemical waste are mixed with the rain water then that chemical waste has to be in the gas form which then condensed and mixed with the water to form the acid in the form of carbonic or sulfuric acid. Thus, such rain is called as the acid rain. Hence, the answer to this question is "c"

24. The gases has to be seen to liberate frm the greenhouse and thus they are trapped in the troposphere in increase the temperature of the surface and overall environmental temperature. Due to such effect, this phenomenon has been termed as the Greenhous effect. Hence, the answer to this question is "c"

25. Yes, it is true that the green house effect is leading to the increase in global warming. Becasue the global warming is the effect where the temperature of the Earth's surface and environment increases and leads to the harmful effects. Hence the answer to this question is "a"
