Questions Related to temperature

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.

The average temperature of a month is the average of the maximum and minimum temperatures for that month.

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

  1. True

  2. False

Show answer
Correct Option: A
Explanation:

The average temperature of a month is the average of the maximum and minimum temperatures of that month. Atmospheric temperature is a measure of temperature at different levels of the Earth's atmosphere. It is governed by many factors, including incoming solar radiation, humidity, and altitude.

Which of the following is/are heat zone/s of the earth?

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

  1. Torrid Zone

  2. Temperate Zone

  3. Frigid Zone

  4. All of the above

Show answer
Correct Option: D
Explanation:

On the basis of the distribution of temperature  earth is divided  into the following  heat zones, 

  • Torrid zone: It extends on both side of the equator and is bounded by the Tropic of Cancer and Capricorn. That is between 23 degrees half minute  North and 23 degree half minute South latitudes. 
  • Temperate zone: It extends in one each of the two hemispheres.  They lie between the Tropic of Cancer and Arctic Circle in the northern and between Tropic of Capricorn and Arctic Circle in the southern hemisphere. That is between 23 degrees half minute North to 66 degrees half minute North and 23 degrees half minute South and 66 degrees half minute South latitudes. 
  • Frigid zone: It extends in two hemispheres.  The fried zone in Northern hemisphere lies between Arctic Circle and the North Pole and in the southern hemisphere between Antarctic circle and South pole. 

Which of the following heat zone receive maximum Insolation?

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

  1. Torrid Heat Zone

  2. Temperate Heat Zone

  3. Frigid Heat Zone

  4. All of these

Show answer
Correct Option: A
Explanation:

The torrid zone is the area of the earth between the Tropic of Cancer and the Tropic of Capricorn. It is also known as the tropical zone. The temperature in this zone is  warm, humid and moist throughout the year. The sun is directly overhead at least once in a year in the tropic zone. So this torrid zone receive maximum insolation.

Torrid Heat Zone lies between __________.

  1. Tropic of Cancer and Arctic Circle

  2. Tropic of Capricorn and Antarctic Circle

  3. Tropic of Cancer and Tropic of Capricorn

  4. Tropic of Cancer and Tropic of Antarctic

Show answer
Correct Option: C
Explanation:

Torrid heat zone lies between Tropic of Cancer and Capricorn. It is the hottest heat zone on the earth. It extends on both sides of the equator.  That is between 23 degrees half minute North and 23 degrees half minute South latitudes.
