Answer 2

Greenhouse gases occur naturally in the atmosphere.

Explanation:

• Greenhouse effect is a natural process that warms the earth's surface.
• The highest quantities of carbon dioxide which gets produced by burning fossil fuels is said to be the greenhouse gases.
• Gases that trap heat in the atmosphere is called greenhouse gases.
• Many greenhouse gases such as carbon dioxide, methane, water vapour, nitrous oxide etc. occur naturally in the atmosphere.
• When the energy from the sun reaches the atmosphere, some of the energy will get reflected back to the space.
• Apart from the reverted rays, the rest of the rays are absorbed and re-radiated by green house gases.
• The energy which gets absorbed warms the atmosphere and the surface of the earth.
• Each of these gases can remain in the atmosphere for different period of time ranging from a few years to thousands of years.
