Which is the coldest heat zone on the earth?

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

  1. Torrid Zone

  2. Frigid Zone

  3. Temperate Zone

  4. None of these

Show answer
Correct Option: B
Explanation:

The frigid zone is the coldest heat zone on the earth. It found one each in the two hemispheres. The Frigid zone in the northern hemisphere lies between Arctic Circle and the North pole and in the southern hemisphere between Antarctic Circle and South pole.

Which is the hottest heat zone on the earth?

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

  1. Torrid Zone

  2. Frigid Zone

  3. Temperate Zone

  4. None of these

Show answer
Correct Option: A
Explanation:

The torrid zone is the hottest heat zone on the earth. 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 degrees half minute South latitudes. 

Which one the following is not a mechanism of heat transfer?

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

  1. Conduction

  2. Condensation

  3. Radiation

  4. Convection

Show answer
Correct Option: B
Explanation:

Conduction, Convection & Radiation. There are three main ways that heat is transferred between substances or objects.

The coldest hour of the day is _________.

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

  1. 5 am.

  2. 9 pm.

  3. 4 am.

  4. 10 am.

Show answer
Correct Option: C
Explanation:

The coldest time of day is just about the time of sunrise because this is the time at which the atmosphere is without the heat of the sun for the longest time. The lowest temperature of the day usually occurs then i.e. 4a.m.

Ocean current is a powerful factor for affecting distribution of ____________.

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

  1. temperature

  2. pressure

  3. heat

  4. none of these

Show answer
Correct Option: A
Explanation:

Ocean current is a powerful factor for affecting the distribution of temperature. The effect of ocean current upon the temperature of adjacent land areas are variable, depending on the direction of prevailing wind. The warm ocean currents help to raise the temperature of the adjoining regions.  On the other hand, cold ocean currents lower down the temperature of the adjoining region.

North Atlantic Drift raises the winter temperature of _____________.

  1. North-West Europe.

  2. North-east Europe.

  3. Both a and b

  4. None of these

Show answer
Correct Option: A
Explanation:

North - West Europe,

The relatively warm waters of the North Atlantic Drift are responsible for moderating the climate of western Europe, so that winters are less cold than would otherwise be expected at its latitude. Without the warm North Atlantic Drift, the UK and other places in Europe would be as cold as Canada, at the same latitude.

The rate of decrease of temperature with height is about __________$^0c$ per km above sea level.

  1. 6

  2. 7

  3. 8

  4. 9

Show answer
Correct Option: A

Temperature decreases down the valleys, it is known as the _______.

  1. Inversion of temperature

  2. Inversion of heat

  3. Inversion of pressure

  4. none of these

Show answer
Correct Option: A
Explanation:

Temperature decreases down the valley, it is known as the inversion of temperature. Especially during the winter nights the temperature increase with the altitude. This is mainly due to rapid radiation from the ground and on account of the flow of heavy cold air down the valley.

Sun's rays pass through _______ to great depth.

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

  1. air

  2. water

  3. heat

  4. none of these

Show answer
Correct Option: B
Explanation:

Water,

Sunlight entering the water may travel about 1,000 meters (3,280 feet) into the ocean under the right conditions, but there is rarely any significant light beyond 200 meters (656 feet). Only a small amount of light penetrates beyond this depth.

Temperature of the atmosphere and altitude are _____.

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

  1. interrelated

  2. different

  3. same

  4. none of these

Show answer
Correct Option: A
Explanation:

A temperature of the atmosphere and altitude are interrelated. The temperature of the atmosphere decrease with increasing altitude from the earth's surface. This vertical decrease in temperature of the atmosphere is limited to the troposphere. The atmosphere is heated mainly from below. Therefore, within the troposphere, as we go higher temperature gradually decreases to about 6.5 degrees C per km. Sometimes, especially during cold winter nights the temperature increase with the altitude. This is mainly due to the rapid radiation from the ground and on account of the flow of heavy cold air down the valley.
