Questions Related to elements of weather and climate : temperature

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


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

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

  1. long waves

  2. short waves

  3. transverse waves

  4. longitudinal waves


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 ______________.

  1. solar radiation

  2. insolation

  3. terrestrial radiation

  4. ultraviolet rays


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?

  1. 30%

  2. 35%

  3. 40%

  4. 45%


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 ___________.

  1. solar light

  2. heat balance

  3. terrestrial radiation

  4. insolation


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.

The solar radiation can be divided into ________.

  1. white light

  2. ultraviolet rays

  3. infrared rays

  4. all of the above


Correct Option: D
Explanation:

The solar radiation can be divided into three parts, namely, white light, ultraviolet rays and infrared rays.

White light: The white are also known as visible rays of the sun.  white light helps us the see any object. This light can not be seen but can be observed.
Ultraviolet rays: Ultraviolet Ray in very harmful rays come from the sun. They are responsible for many skin diseases. The wavelength is shorter than white light but longer than x rays.
Infrared rays: The wavelength of this Ray is longer than white Ray and ultraviolet rays. Most of the sun's energy comes in the form of infrared rays. This ray is also used in night vision devices.

What percent of the insolation is absorbed by the atmosphere?

  1. 10%

  2. 12%

  3. 17.5%

  4. 20%


Correct Option: C
Explanation:
The budget for solar radiation is as follows (percentage)
Reflected: 35%
Absorbed by atmosphere: 17.5%
Scattered to the Earth from the blue sky: 10.5%
Scattered to the Earth from clouds: 14.5%
Radiation going directly to Earth's surface: 22.5%

The naturally occurring bright light which is seen in the polar regions is known as __________.

  1. Aurora Borealis

  2. Aurora Australis

  3. Ultra violet radiation

  4. Both A and B


Correct Option: D
Explanation:

The bright lights are a natural phenomenon found in both the northern and southern hemispheres of Polar region that can be truly awe-inspiring. Northern lights are called Aurora Borealis and southern lights are called Aurora Australis.
