Show answer
Correct Option: C
Explanation:

The Köppen climate classification defines a climate as "temperate" when the mean temperature is above −3 °C (26.6 °F) but below 18 °C (64.4 °F) in the coldest month.

  1. Natural

  2. Commercial

  3. Both A and B

  4. None of these

Show answer
Correct Option: A
Explanation:

A greenhouse is a body which allows the shortwave incoming solar radiation to come in but does not allow the longwave outgoing terrestrial infrared radiation to escape. The greenhouse effect is a natural phenomenon which helps in keeping the earth's surface warm up. Carbon dioxide, water vapour etc are the important gases of the greenhouse.

Ozone layer protects the earth from ____________.

  1. X-rays

  2. Infra-red rays

  3. Cosmic rays

  4. Ultra-violet rays

Show answer
Correct Option: D
Explanation:
  • The ozone layer blocks the harmful ultra-violet rays coming from the sun and prevents it from reaching the earth's surface thus play an extremely important role. However it cannot block x-rays, infrared rays or cosmic rays. Hence option D is correct.
  • The ozone layer is found in the lower stratosphere 

'Green House Effect' means ________________.

  1. Pollution in houses in tropical regions

  2. Trapping of solar energy due to atmospheric oxygen

  3. Trapping of solar energy due to atmospheric carbon dioxide

  4. Cultivation in green houses so as to check pollution

Show answer
Correct Option: C

  1. Troposphere

  2. Stratosphere

  3. Mesosphere

  4. Thermosphere

Show answer
Correct Option: B
Explanation:
stratosphere
The ozone layer is mainly found in the lower portion of the stratosphere, from approximately 15 to 35 kilometers (9.3 to 21.7 mi) above Earth, although its thickness varies seasonally and geographically.
