What factors are responsible for Insolation variation?

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

  1. The angle of inclination of the suns rays

  2. The length of the day

  3. The transparency of the atmosphere

  4. all of these

Show answer
Correct Option: D
Explanation:

The conditions of the atmosphere as well as the seasons affect the actual amount of insolation received at a place on the earth. Following are the factors which are responsible for variation in insolation:-

  1. Angle of inclination of the sun rays
  2. Length of the day
  3. Transparency of the atmosphere
  4. Solar constant
  5. Distance between the earth and the sun

The energy radiated out in the space by earth's surface is called _______________.

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

  1. Solar radiations

  2. Terrestrial radiations

  3. Radioactivity

  4. Insolation

Show answer
Correct Option: B
Explanation:
  • The energy from the sun to earth comes in the form of solar radiation while the earth radiates it back to the atmosphere in the form of terrestrial radiations, hence option B is correct.
  • Radioactivity is the energy released with the breakdown of matter in the form of gamma rays.
  • Insolation is the reduction of energy transfer between objects.

The incoming solar radiation in the form of short waves is called _____________.

  1. Insolation

  2. Sleet

  3. Drizzel

  4. Terrestrial radiations

Show answer
Correct Option: A
Explanation:
  • Incoming solar radiation from the sun is called insolation.
  • Terrestrial radiation is the energy radiated back by the earth to the atmosphere.
  • Sleet is partly frozen rain
  • Drizzle is light rain falling with very small droplets.

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 _________.

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

  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 ________.

Which is the hottest place of the word?

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

  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.
