Question

 CO₂, CFCs and Chlorine belong to a category of chemicals known as greenhouse gases. Excess presence of these gases in the atmosphere leads to

1. global warming
2.  protecting the ozone layer
3.  heavy rains
4. loss of soil fertility

Answer 1

Correct Answer - Option 1 : global warming

Explanation:

Greenhouse effect

• The greenhouse effect is a natural process that warms the Earth's surface.
• 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.
• That trapping of heat is known as the greenhouse effect.
• Greenhouse gases in the atmosphere absorb the infrared radiations of higher wavelengths and warm the atmosphere, This phenomena is known as global warming.
• Excess presence of green house gases such as, CO₂ , CFCs and chlorine causes global warming.
