Question

Earth’s Natural Greenhouse Effect Is Due To:
A. Water Vapour
B. Clouds
C. Both A and B
D. None of The Above

Answer 1

Hint: To give the answer of this question, first of all we see the definition of greenhouse effect and gases which cause greenhouse effect, also we see the reason for increased greenhouse. Greenhouse gas is the main reason to do global warming and cause of greenhouse effect and global warming.

Complete step-by-step answer:
The greenhouse effect is a natural process. It arises from earth’s atmosphere. It is a process when gases in earth’s atmosphere trap the sun’s heat. In this process earth temperature increases.
Greenhouse gases are most affected by water vapour, clouds, carbon dioxide, methane, nitrous oxide ozone and some chemicals such as chlorofluorocarbons. These all gases absorb infrared radiation. By increasing the heat in the atmosphere and warming the planet.
Greenhouse effect occurs naturally by both water vapour and clouds. Cloud plays a role in natural greenhouse effect, it covers earth and sun light not appears on earth surface. Water vapour is the most abundant greenhouse gas. It differs from other greenhouse gases because its atmospheric concentrations are linked not to human activities. As increased water vapour also increases cloud cover that reflects the sun’s light away from the earth.
The increases of earth’s average surface temperature due to the effect of greenhouse gases are global warming.
So, option A is the correct answer.

Note- Main reason for the emission of greenhouse and global warming is caused and effects by the burning of coal, it produces carbon dioxide and methane gas. Methane gas is more powerful than carbon dioxide. Nitrous oxide, also a greenhouse gas produced during nitric acid and nylon production. In the recent nitrous oxide decades leading global warming. Melting of glaciers, rise in sea levels and river water levels are major examples of global warming.
