Question

Greenhouse effect is a major cause of:
(A) Global warming
(B) Reduction of temperature
(C) Acid rain
(D) All of the above

Answer 1

Hint : To answer this question, we need to understand what greenhouse effect is. Greenhouse effect is the process by which radiations from the sun are absorbed by the greenhouse gases and then reflected back into space, which insulates the surface of the earth and prevents it from freezing.

Complete Step By Step Answer:
A greenhouse is a glass structure that is used to cultivate plants. The greenhouse's plants and air are warmed by the sun's rays. The heat trapped within cannot escape, warming the greenhouse, which is essential for plant growth.
The same is true of the earth's atmosphere. The sun heats the earth's atmosphere throughout the day. Heat is radiated back into the atmosphere when the planet cools at night. The heat is absorbed by the greenhouse gases in the earth's atmosphere during this process. This is what keeps the earth's surface warm, and what allows living things to survive on the planet.
The increased volumes of greenhouse gases such as carbon dioxide and methane emitted by the combustion of fossil fuels, as well as pollution from cars, industries, and other human activities, are the primary cause of fluctuation in temperatures of the environment, thus causing global warming ( heating up of earth’s atmosphere) and reduction in temperature.
Many of the world's water sources have become acidic as the overall amount of greenhouse gases in the environment has increased. Acid rain is formed when greenhouse gases combine with rainwater. Water bodies become acidified as a result of this.
Hence correct option is (A).

Note :
The major causes of greenhouse effect include burning of fossil fuels, deforestation, farming, filling of landfills with industrial and domestic waste. Greenhouse effect needs to be minimized in order to create a healthy atmosphere.
