Question

 ______ is a naturally occurring phenomenon that is responsible for the heating of the Earth’s surface and atmosphere.
1. Greenhouse effect
2. Global heating
3. Radiation
4. Global warming

Answer 1

Correct Answer - Option 1 : Greenhouse effect

The correct answer is Greenhouse effect.

• The greenhouse effect is a process that occurs when gases in Earth's atmosphere trap the Sun's heat.
• This process makes Earth much warmer than it would be without an atmosphere.
• A greenhouse is a building with glass walls and a glass roof and used to grow plants.
• It leads to an increase in the Earth's temperature because the glass walls of the greenhouse trap the Sun's heat.

 

• Radiation is the energy that comes from a source and travels through space at the speed of light like heat, light, ultraviolet rays, etc.
• The increase in the Earth's average temperature over the past few decades is called Global warming.
• Global warming occurs when carbon dioxide (CO2) and other air pollutants and greenhouse gases are collected in the atmosphere and absorb sunlight and solar radiation that have bounced off the earth’s surface.
