Current Question (ID: 17860)

Question:

$\text{In the absence of greenhouse gases -}$

Options:

1. $\text{Life on earth would be impossible.}$
2. $\text{Average temperature of the earth will decrease drastically.}$
3. $\text{There will be no effect on Earth}$
4. $\text{Both (1) and (2)}$

Solution:

$\text{HINT: Earth's most abundant greenhouse gases are } \text{CO}_2, \text{CH}_4, \text{O}_3, \text{CFCs, and water vapour.}$ $\text{Explanation:}$ $\text{These gases are present near the Earth's surface. They absorb solar energy that is radiated back from the surface of the Earth.}$ $\text{The absorption of radiation results in the heating up of the atmosphere. Hence, greenhouse gases are essential for maintaining the temperature of the Earth for the sustenance of life.}$ $\text{In the absence of greenhouse gases, the average temperature of the Earth will decrease drastically, making it uninhabitable. As a result, life on Earth would be impossible.}$
