Carbon dioxide plays a vital role in changing the earth's climate, leading to a critical condition known as ________.

Show answer & explanation

Correct answer: A

Explanation

The correct answer is  option 1  i.e. Greenhouse Effect.

Carbon dioxide (CO₂) plays a vital role in changing the Earth's climate, leading to a critical condition known as the Greenhouse Effect.

The greenhouse effect is a natural process where certain gases in Earth's atmosphere, including CO₂, trap heat from the Sun. This trapped heat helps maintain temperatures that support life. However, human activities, particularly the burning of fossil fuels, have increased CO₂ concentrations, intensifying this effect and leading to global warming. This warming disrupts climate patterns, causing more frequent and severe weather events, rising sea levels, and other environmental impacts.

Incorrect Options:

  1. Temperature Convection – Refers to the movement of heat through fluids (like air or water), not directly linked to CO₂’s climate impact.

  2. Ozone Depletion – Caused by CFCs, not CO₂. It affects the ozone layer, not the greenhouse effect.

  3. Thermal Conduction – The process of heat transfer through solids; unrelated to atmospheric CO₂ or climate change.
