Question

Assertion (A): Climate change is a result of increased GHG emissions.

Reason (R): Use of fossil fuels, population growth and reduced green cover result in GHG emissions.

Options

• Both A and R are true and R is the correct explanation of A.

• Both A and R are true but R does not explain A.

• A is true but R is false.

• A is false but R is true.

Answer 1

Both A and R are true and R is the correct explanation of A.

Explanation:

Greenhouse gases (CO2, CH4, N2O, etc.) trap outgoing infrared radiation and warm the Earth. Burning fossil fuels, greater energy use from population growth, and loss of green cover raise GHG concentrations causing climate change.
