Current Question (ID: 17855)

Question:

$\text{The phenomenon in which atmospheric gases trap the heat radiations from the sun near the earth's surface and keeps it warm is known as-}$

Options:

1. $\text{Natural greenhouse effect}$
2. $\text{Tyndall effect}$
3. $\text{Heating effect}$
4. $\text{Joule's effect}$

Solution:

$\text{HINT: Greenhouse effect.}$ $\text{Explanation:}$ $\text{The greenhouse effect is a natural process that warms the Earth's surface.}$ $\text{When the Sun's energy reaches the Earth's atmosphere, some of it is reflected back to space and the rest is absorbed and re-radiated by greenhouse gases.}$ $\text{The absorbed energy warms the atmosphere and the surface of the Earth.}$ $\text{Gases show natural greenhouse effect } = \text{CO}_2 , \text{SO}_2 , \text{SO}_3 , \text{NO}_x$
