Arrange the following in the order in which they occur in the problem of global warming:
(A) A rise in sea level and coastal flooding
(B) Burning of fossil fuels adds carbon dioxide to the atmosphere
(C) A gradual increase in the average temperature of the earth’s lower atmosphere
(D) Melting of polar ice
Choose the correct answer from the options given below:
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → (B), (C), (D), (A)
Global warming works as a chain of cause and effect.
(B) Burning of fossil fuels adds carbon dioxide to the atmosphere — Burning fossil fuels raises the level of greenhouse gases.
(C) A gradual increase in the average temperature of the earth’s lower atmosphere — More greenhouse gases make the lower atmosphere warmer.
(D) Melting of polar ice — The warmth melts polar ice.
(A) A rise in sea level and coastal flooding — Melting ice raises the sea level, which floods coasts.
NCERT (2026-27): “Box 7.1: Global Warming Global warming is a gradual increase in the average temperature of the earth’s lower atmosphere as a result of the increase in greenhouse gases since the Industrial Revolution. Much of the recent observed and projected global warming is human-induced. It is caused by man-made increases in carbon dioxide and other greenhouse gases through the burning of fossil fuels and deforestation. … Some of the longer-term results of global warming are melting of polar ice with a resulting rise in sea level and coastal flooding; disruption of drinking water supplies dependent on snow melts; extinction of species as ecological niches disappear; more frequent tropical storms; and an increased incidence of tropical diseases. …” |
