Questions Related to environmental regions (zones)

Capacity of atmospheric air to contain water vapours is directly proportional to its ____________.

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

  1. Pressure

  2. Temperature

  3. Density

  4. Distance from the equator

Show answer
Correct Option: B
Explanation:

As the temperature of the air increases its capacity to hold moisture increases while with the decrease in the temperature of the air, its capacity to hold moisture decreases. Thus the capacity of the atmospheric air to contain water vapor is directly proportional to its temperature. Hence option B is correct.

With respect to isotherm, consider the following statements:

1. The Isotherms are lines joining places having equal temperature.

 2. In January the isotherms deviate to the south over the Ocean and to the north over the continent in the northern hemisphere.

  1. 1 only

  2. 2 only

  3. 1 and 2

  4. none of these

Show answer
Correct Option: A
Explanation:

Isotherms are imaginary lines joining places of equal temperature. For convenience, the temperature are reduced to sea level as if the places actually existed at sea level. The spacing of isotherms indicated the steepness of temperature change. Closely spaced isotherms indicated higher thermal gradient.

During October, the temperature in the Northern Hemisphere starts dropping because _________.

  1. The sun's rays fall vertically on the Southern Hemisphere

  2. The sun's rays fall obliquely on the Southern Hemisphere

  3. The sun's rays fall vertically on the equator

  4. The sun's rays fall vertically on the Northern Hemisphere

Show answer
Correct Option: A

During the summer season, the temperature is not high in South India because __________________.

  1. Of local temperature and winds

  2. Sun's rays are perpendicular in the norther hemisphere

  3. It is surrounded by water on three sides

  4. Distance from the sea and high temperature

Show answer
Correct Option: C

Ganganagar in Rajasthan has recorded the maximum temperature of ________.

  1. ${20}^{o}C$

  2. ${40}^{o}C$

  3. ${48}^{o}C$

  4. ${52}^{o}C$

Correct Option: D

Which is the hottest place of the word?

  1. Aziziyah

  2. Seville

  3. Death Valley

  4. Jacobabad

Show answer
Correct Option: A

The solar radiation radiate back to the atmosphere in the form of _____________.

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

  1. long waves

  2. short waves

  3. transverse waves

  4. longitudinal waves

Show answer
Correct Option: A
Explanation:

The earth receives solar energy in form of short-wave solar recitation.On the other hand solar radiation is radiated back to the atmosphere in the form of long-wave terrestrial rediation.

The heat which goes back to the atmosphere in the form of long waves is called ______________.

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

  1. solar radiation

  2. insolation

  3. terrestrial radiation

  4. ultraviolet rays

Show answer
Correct Option: C
Explanation:

Earth receives solar radiation in the form of short-wave solar radiation, where it converted into heat by the process of absorption. This energy goes back in the form of long-wave terrestrial ration. The earth sends the same amount of energy back to the spacer, except for a small amount of energy stored as fossil fuels.

What percent of the insolation is reflected back to space by dust and clouds present in the atmosphere?

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

  1. 30%

  2. 35%

  3. 40%

  4. 45%

Show answer
Correct Option: B
Explanation:

About one third i.e 35% of the solar energy is reflected back (like a mirror reflecting light) by the Earth’s atmosphere. Further, some portion of the light is scattered and absorbed in the higher reaches of the atmosphere. In fact, some of the harmful rays of Sun like the UV rays don’t reach the ground and this has made life possible on the Earth. 

The amount of solar radiation received by the surface of the earth is called ___________.

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

  1. solar light

  2. heat balance

  3. terrestrial radiation

  4. insolation

Show answer
Correct Option: D
Explanation:

The amount of solar radiation received by the surface of the earth is called insolation. The word insolation means incoming solar radiation. It consists of a bundle of rays of radient energy of different wavelengths. The sun emits radient energy in the form of electromagnetic waves.
