From March to May, the temperature will be high in North India because of _____________________.

geography temperature process of heat transfer in the atmosphere temperature and insolation sun: the ultimate source

  1. Long nights and distance from the sea

  2. Long days and nearness to the sea

  3. Long nights and nearness to the sea

  4. Long days and distance from the sea

Show answer
Correct Option: D

The circle drawn from $23\dfrac {1}{2}^{\circ}$ from the North Pole is called ________________.

geography temperature process of heat transfer in the atmosphere temperature and insolation sun: the ultimate source

  1. Arctic Circle

  2. Antarctic Circle

  3. North Frigid Zone

  4. North Temperature Zone

Show answer
Correct Option: A
Explanation:
  • 23 and half degrees from the pole refers to the 66 and half degree from the equator ir the Arctic circle, hence option A is correct.

Temperature varies from place to place with latitude and altitude. It may increase or decrease depending upon the factors that affect temperature. Certain anomalies may also develop on account of tmique combination of factors. The inversion of temperature would mean that the _____________.

geography temperature process of heat transfer in the atmosphere temperature and insolation sun: the ultimate source

  1. Temperature decreases with elevation

  2. Temperature is constant at different eleations

  3. Temperature decreases and then increases with elevation

  4. Temperature changes along the same latitude

Show answer
Correct Option: C

Which of the following place will never get the vertical rays of the sun?

geography temperature process of heat transfer in the atmosphere temperature and insolation sun: the ultimate source

  1. Srinagar

  2. Thiruvanthapuram

  3. Chennai

  4. Mumbai

Show answer
Correct Option: A

Gases like ______ prevent the escaping radiation of heat from the earth.

geography temperature process of heat transfer in the atmosphere temperature and insolation sun: the ultimate source

  1. Carbondioxide

  2. Carbonmonoxide

  3. Nitrogen

  4. Oxygen

Show answer
Correct Option: A
Explanation:

Carbon dioxide is a greenhouse gas, which prevents the escaping of heat from the earth.

Greenhouse Gases. Earth's atmosphere is composed primarily of nitrogen and oxygen. These gases are transparent to incoming solar radiation. They are also transparent to outgoing infrared radiation, which means that they do not absorb or emit solar or infrared radiation.

The atmosphere warms up by the process of _______.

geography temperature process of heat transfer in the atmosphere temperature and insolation sun: the ultimate source

  1. radiation

  2. conduction

  3. convection

  4. all of the above

Show answer
Correct Option: D
Explanation:

The atmosphere warms up by the following processes:

1.  Radiation: It is the direct heating by the transmission of heat waves. The upper layer of atmosphere absorbs some amount of heat from the rays of the sun as they pass through the atmosphere.
2. Conduction: It is a process of transfer of heat by molecular activity. When two bodies with unequal temperature come into contact, there is a flow of energy from the warmer body to the cooler one. The lower layer of the atmosphere heated through the process of conduction.
3. Conversation: Transfer of heat of atmosphere from one place to another is known as conversation. Conversation is the main process in the heating of the atmosphere.

Which of the following term is used for transfer of heat through winds?

geography temperature process of heat transfer in the atmosphere temperature and insolation sun: the ultimate source

  1. Conduction

  2. Convection

  3. Advection

  4. None of the above

Show answer
Correct Option: C
Explanation:

The term advection is used for horizontal transport of heat. Advection is responsible for slow heat transfer from the equatorial regions to the polar region. This process of heat transfer is relatively more important than any other method. The scorching winds blowing during the summer in the northern plains of India, which are known as Loo, are a typical example of advection.

The lower layer of the atmosphere gets heated by the process of ___________.

geography temperature process of heat transfer in the atmosphere temperature and insolation sun: the ultimate source

  1. conduction

  2. convection

  3. advection

  4. none of the above

Show answer
Correct Option: A
Explanation:

Conduction is a slow process of heat transfer as regards warming of the atmosphere. Since air is a very poor conductor of heat, the conduction process affects only the lowermost layers of air closest to the earth's surface. As a means of heat transfer for the atmosphere as a whole, conduction is the least important and can be neglected when considering a majority of meteorological phenomena.

The transfer of heat in the atmosphere by air currents is called ____________.

geography temperature process of heat transfer in the atmosphere temperature and insolation sun: the ultimate source

  1. conduction

  2. convection

  3. advection

  4. radiation

Show answer
Correct Option: B
Explanation:

Since the atmosphere is a gaseous medium, convection is the most significant mechanism of heat transfer. Heat gained by the layers of air at or near the earth's surface from radiation or conduction is usually transferred to the upper atmospheric layers by the process of convection. Thus convection is the transfer of heat in the atmosphere by the air current.

The state of equilibrium that exists on Earth between insolation and terrestrial radiation is called ___________.

geography temperature process of heat transfer in the atmosphere temperature and insolation sun: the ultimate source

  1. insolation

  2. heat balance

  3. heat equilibrium

  4. none of the above

Show answer
Correct Option: B
Explanation:

Earth receives solar radiation in the form of short-wave solar radiation and the radiation is sent back to space in the form of longwave terrestrial radiation. In the absence of such a balance the earth would be getting progressively colder or progressively warmer. This balance between the amount of insolation received from the sun and outing outgoing terrestrial radiation is known as earth's heat budget or heat balance.
