(a)

(b)

(c)

(d)

Explanation:

In absorption of isolation the most significant part is played by Carbon dioxide.


Q-5)   In which of the following countries of Africa, dense, hot and humid forest are found?

(a)

(b)

(c)

(d)


Q-6)   Wind rose represents

(a)

(b)

(c)

(d)

Explanation:

A wind rose is a graphic tool used by meteorologists to give a succinct view of how wind speed and direction are typically distributed at a particular location.


Q-7)   Which of the following would you generally associate with Tornadoes?

(a)

(b)

(c)

(d)


Q-8)   Consider the following statements
  1. Ozone is mostly found in the stratosphere
  2. Ozone layer lies 25 to 30 km above the surface of the Earth
  3. Ozone absorbs ultraviolet radiation from the Sun.
  4. Ozone layer has no significance for life on the Earth
Which of the statements given above is/are correct?

(a)

(b)

(c)

(d)

Explanation:

The ozone layer or ozone shield is a region of Earth’s stratosphere that absorbs most of the Sun’s ultraviolet (UV) radiation.

It contains high concentrations of ozone (O3) in relation to other parts of the atmosphere, although still small in relation to other gases in the stratosphere.


Q-9)   Which one of the following climates are associated with the shifting of the pressure belts?
  1. Equatorial climate
  2. Mediterranean climate
  3. Monsoon climate
  4. Western European climate
Select the correct answer from the code given below.

(a)

(b)

(c)

(d)

Explanation:


Q-10)   What is the term used to denote the temperature at which the water vapour present in the atmosphere is sufficient to saturate?

(a)

(b)

(c)

(d)

Explanation:

Dew point is the temperature at which the air is fully saturated and below which condensation normally occurs, water vapour starts to condense to form water droplets.


Q-11)   The layer of the atmosphere in which Radio Waves are reflected back is called ;

(a)

(b)

(c)

(d)

Explanation:

The Radio waves are reflected back to Earth in the Ionosphere which is an electrically charged layer of the upper atmosphere.

This process is used to communicate beyond the horizon, at intercontinental distances, mostly in the shortwave frequency bands.


Q-12)   Which of the following clouds are more commonly formed in the equatorial rainforests?

(a)

(b)

(c)

(d)


Q-13)   Thunder cloud develops due to

(a)

(b)

(c)

(d)

Explanation:

Thunder cloud develops due to high temperature and high humidity.


Q-14)   Consider the following atmospheric conditions with reference to Tropical cyclones.
  1. High relative humidity.
  2. Warm oceanic temperature.
  3. The region lying between the tropics of cancer and Capricorn.
Which of the above motivate the development of cyclone?

(a)

(b)

(c)

(d)

Explanation:

There are six main requirements for tropical cyclogenesis:

  1. Sufficiently warm sea surface temperatures, atmospheric instability,
  2. High humidity in the lower to middle levels of the troposphere,
  3. Enough Coriolis force to sustain a low-pressure centre,
  4. A preexisting low-level focus or disturbance, and low vertical wind shear,
  5. While these conditions are necessary for tropical cyclone formation and
  6. They do not guarantee that a tropical cyclone will form.


Q-15)   Storms of gases are visible in the chromosphere of the Sun during

(a)

(b)

(c)

(d)

Explanation:

As seen from the Earth, a solar eclipse occurs when the Moon passes between the Sun and Earth, and the Moon fully or partially blocks the Sun.

This can happen only at the new moon when the Sun and the Moon are in conjunction as seen from Earth. In a total eclipse, the disk of the Sun is fully obscured by the Moon.

In partial and annular eclipses only part of the Sun is obscured. The moon blocks out the bulk of the sun allowing us to see the chromosphere and corona.


Q-16)   Ozone layer of the Earth’s atmosphere is important for living organisms because it

(a)

(b)

(c)

(d)

Explanation:

The ozone layer refers to a region of Earth’s stratosphere that absorbs most of the Sun’s ultraviolet (UV) radiation. Ultra Violet radiation is very harmful to all living things.

UV radiation can be harmful to the skin and is the main cause of sunburn; excessive exposure can also cause cataracts, immune system suppression, and genetic damage, and skin cancer.


Q-17)   Which of the following does not affect the distribution of insolation?

(a)

(b)

(c)

(d)

Explanation:


Q-18)   Mediterranean type of climate is characterized by

(a)

(b)

(c)

(d)

Explanation:

The climate is characterized by warm to hot, dry summers and mild to cool, wet winters. Mediterranean climate zones are associated with the five large subtropical high-pressure cells of the oceans:

  1. the Azores High,
  2. South Atlantic High,
  3. North Pacific High,
  4. South Pacific High, and
  5. Indian Ocean High.

These high-pressure cells shift towards the poles in the summer and towards the equator in the winter, playing a major role in the formation of the world’s tropical deserts and the Mediterranean Basin’s climate.
