• A. Deforestation
• B. Melting ice sheets
• C. Burning of fossil fuels
• D. Rise in sea level

Answer 1

Answer: (A), (C)

The correct options are
A Deforestation
C Burning of fossil fuels

Deforestation is the removal of forest cover. Trees take up carbon dioxide and release oxygen. Trees also give off water vapour and have a cooling effect on the environment. When tree cover is lost, it increases the carbon dioxide content in the atmosphere, resulting in an elevation of temperature in the surrounding areas. Burning of fossil fuels release greenhouse gases like carbon dioxide and methane. These gases trap heat and cause global warming.
