The heat which goes back to the atmosphere in the form of long waves is called ______________.

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

  1. solar radiation

  2. insolation

  3. terrestrial radiation

  4. ultraviolet rays

Show answer
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?

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

  1. 30%

  2. 35%

  3. 40%

  4. 45%

Show answer
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 ___________.

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

  1. solar light

  2. heat balance

  3. terrestrial radiation

  4. insolation

Show answer
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 ________.

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

  1. white light

  2. ultraviolet rays

  3. infrared rays

  4. all of the above

Show answer
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?

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

  1. 10%

  2. 12%

  3. 17.5%

  4. 20%

Show answer
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 __________.

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

  1. Aurora Borealis

  2. Aurora Australis

  3. Ultra violet radiation

  4. Both A and B

Show answer
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.

Into how many temperature zones the earth can be divided?

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

  1. Two

  2. Three

  3. Four

  4. Five

Show answer
Correct Option: C
Explanation:

The earth can be divided into four temperature zones. They are, 

1. Torrid zone:  It extends on both sides of the equator bounded by the tropic of cancer and tropic of Capricorn. In this area sun's rays are more or less perpendicular. The temperature in this area is always high.
2. North Temperate zone: This area is between tropic of cancer and Arctic circle in the northern hemisphere. Sun rays do not fall perpendicularly nor slanting at this place. So places within this area neither too hot not too cold.
 3. South Temperate zone: This area is between the Tropic of Capricorn and Antarctica circles. Here temperature is neither too hot nor too cold.
4. Frigid zone: The frigid zone in the northern hemisphere lies Arctic circle and the North Pole and in the southern hemisphere between Antarctic circle and south pole. They receive very little heat from the sun and hence very cold.

The solar energy which reaches the earth in the form of short waves is called ____.

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

  1. ultravioletrays

  2. global warming

  3. insolation

  4. radiation

Show answer
Correct Option: C
Explanation:

Our sun is the main source of energy and heat. It provides solar energy or fuel for the process of weather and climate. The energy emitted by the sun is known as solar radiation. The incoming radiation to the earth is known as isolation and it reaches in the earth in form of short waves.

Sensitivity of a thermometer refers to _________.

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

  1. Amount of change in thermometric property for a unit change in temperature

  2. Minimum and maximum temperatures that thermometer can measure

  3. How quickly thermometer can register change in temperature

  4. None of these

Show answer
Correct Option: A
Explanation:

Sensitivity of a thermometer refers to the amount of change in thermometric property for a unit change in temperature. It refers to the smallest temperature change that can be detected or measured. The range of a thermometer on the other hand refers to the difference between the maximum and the minimum temperature.

In which type of farming, roof is made of either glass or cloth to allow the sun rays to penetrate and sustain the heat inside the building?

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

  1. Organic farming

  2. Greenhouse farming

  3. Inorganic farming

  4. All of the above

Show answer
Correct Option: B
Explanation:

In greenhouse farming, the roof is made of either glasses or cloth to allow the sun rays to penetrate and sustain the heart of the building. In this method of farming the dependency on climate reduces. Mainly flower, vegetable, fruits are grown in greenhouse farming.  Some crops also are grown in this method.  With increasing technology greenhouse farming also increasing day by day.
