Which gas can hold the heat in the atmosphere for a long time?

geography environmental changes elements of weather and climate : temperature process of heat transfer in the atmosphere environmental regions (zones)

  1. Oxygen

  2. Nitrogen

  3. Carbon di oxide

  4. Ozone

Show answer
Correct Option: C
Explanation:

Carbon dioxide can hold the heat in the atmosphere for a long time. It constitutes only 0.03 percent of the dry air. Being an effective absorber of heat from the upper atmosphere as well as the earth, carbon dioxide is considered to be of great climatic significance. This gas emits about half of the absorbed heat back to the earth.

The lines which connects places of equal temperature are called ___________.

geography environmental changes elements of weather and climate : temperature process of heat transfer in the atmosphere environmental regions (zones)

  1. isohytes

  2. isobars

  3. isotherms

  4. contours

Show answer
Correct Option: C
Explanation:

The places having similar temperature conditions are joined by means of imaginary lines known as isotherms. For convenience, the temperature is reduced to sea level as if the places actually existed at sea level. The isotherms have east-west trends and generally follow the latitude. 

The highest recorded temperature is about $58^oC$ at Al-Aziziyah which is in ____________.

geography environmental changes elements of weather and climate : temperature process of heat transfer in the atmosphere environmental regions (zones)

  1. Libya

  2. Algeria

  3. Niger

  4. Sudan

Show answer
Correct Option: A
Explanation:

The highest recorded temperature is about 58 $^oC$ at Al-Aziziyah which lies in Libya. It is located around 25 miles south of Tripoli. World Meteorological Organization had recorded this temperature on 13 September 1922. After exactly 90 years, on 13 September 2012, this record was disqualified. Now, the highest recorded temperature is in Death Valley, California.

The mean annual temperature of a country varies between $7^oC\,\, to\,\, 17^oC$. This country lies in the.

  1. Alpine climate region

  2. Sub-tropical region

  3. Temperate region

  4. Tropical region

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.

Global warming and climate change are two different concepts.

geography environmental changes elements of weather and climate : temperature process of heat transfer in the atmosphere environmental regions (zones)

  1. Yes

  2. No

  3. Can't say

  4. None of these

Show answer
Correct Option: A
Explanation:

Yes,

The term "climate change" is often used to refer specifically to anthropogenic climate change (also known as global warming). Anthropogenic climate change is caused by human activity, as opposed to changes in climate that may have resulted as part of Earth's natural processes.

Greenhouse effect is a ________ phenomenon to keep the climate warm up.

geography environmental changes elements of weather and climate : temperature process of heat transfer in the atmosphere environmental regions (zones)

  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 ____________.

geography environmental changes elements of weather and climate : temperature process of heat transfer in the atmosphere environmental regions (zones)

  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

The living being who causes maximum pollution to the environment is _________.

  1. Human being

  2. Noise

  3. Air

  4. Eco-science

Show answer
Correct Option: A

In which layer of the atmosphere, ozone layer is present?

geography environmental changes elements of weather and climate : temperature process of heat transfer in the atmosphere environmental regions (zones)

  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.
