Question 3

Consider the following statements: I. Without the atmosphere, temperature would be well below freezing point everywhere on the Earth's surface. II. Heat absorbed and trapped by the atmosphere maintains our planet's average temperature. III. Atmosphere's gases, like carbon dioxide, are particularly good at absorbing and trapping radiation. Which of the statements given above are correct?

Accepted Answer

The atmosphere plays a crucial role in maintaining Earth's temperature through the greenhouse effect. Statement I is correct because the atmosphere helps retain heat, preventing temperatures from dropping drastically. Statement II is accurate as the atmosphere absorbs and traps heat, regulating the planet's average temperature. Statement III is true because greenhouse gases like carbon dioxide are efficient at absorbing and trapping radiation, contributing to the greenhouse effect.

Question 4

Consider the following statements: 1. Climate and Clean Air Coalition (CCAC) to reduce Short Lived Climate Pollutants is a unique initiative of G20 group of countries. 2. The CCAC focuses on methane, black carbon and hydrofluorocarbons. Which of the statements given above is/are correct?

The CCAC's focus is on reducing Short Lived Climate Pollutants, including methane, black carbon, and hydrofluorocarbons. Therefore, the second statement is correct.

Question 5

Which of the following statements best describes 'carbon fertilization'?

Accepted Answer

Carbon fertilization refers to the phenomenon where plant growth is enhanced due to higher levels of carbon dioxide in the atmosphere.
