Question 14 of 20
Consider the following statements regarding the contribution of the industrial sector to climate change: I. Heavy industries contribute to global warming solely because they consume massive amounts of electricity generated by fossil fuels. II. The chemical conversion of limestone in cement production directly emits massive amounts of Carbon Dioxide as an unavoidable byproduct. Which of the statements given above is/are correct?
Question 15 of 20
Which natural orbital component involves the gradual change in the geometric shape of the Earth's orbit from circular to elliptical over thousands of years?
Question 16 of 20
Consider the following statements regarding Global Warming and Climate Change: I. Global warming refers exclusively to the continuous and long-term rise in the Earth's average surface temperature. II. Climate change is a broader concept that includes shifts in rainfall distribution, wind systems, ocean currents, and atmospheric pressure belts.

Question 17 of 20
Assertion (A): The National Action Plan on Climate Change (NAPCC) originally consisted of 8 core national missions but was later expanded to include a 9th mission. Reason (R): The rapid rise in demand for fossil fuels in the transportation sector necessitated the creation of the National Electric Mobility Mission to cut tailpipe emissions.
