1

Smog is likely to occur ________

A) Around valleys B) Near lakes C) On calm, clear and cool nights D) Near the industrial areas

Discuss

Answer & Solution

Answer: Option D

Solution:

Smog was common in industrial areas, and remains a familiar sight in cities today. Industrial smog typically exists in urban areas where factories burn fossil fuels such as coal, which creates smoke and sulfur dioxide that mix with fog droplets to create a thick blanket of haze close to the ground.

2

When the top of the cloud begins to look like a head of cauliflower, it's called a cumulus congestus or a towering cumulus. The fluffy, cauliflower-shaped cumulus are one of the most common and distinctive types of cloud. All cumulus clouds develop as a result of convection.

3

Heat gain through insolation and heat loss through terrestrial radiation are equal approximately at which latitude?

A) 22° W North and South B) 40° North and South C) 90° North and South D) 66° W North and South

Discuss

Answer & Solution

Answer: Option B

Solution:

At 40° North and South the heat gain through insolation approximately equal to the heat loss through terrestrial radiation.

4

Increase in carbon dioxide in atmosphere causes ________

A) Rise in earth temperature B) Fall in earth temperature C) Uniform earth temperature D) Increase in Ultraviolet rays

Discuss

Answer & Solution

Answer: Option A

Solution:

The carbon dioxide is released to the atmosphere where it remains for 100 to 200 years. This leads to an increasing concentration of carbon dioxide in our atmosphere (see above on the right hand side), which in turn causes the average temperature on Earth to raise.

5

Which one of the following is not a correct example of tropical cyclone?

A) Tornadoes B) Typhoons C) Hurricanes D) Nor westers

Which one among the following statements relating to an anticyclone is correct?

A) Anticyclone is a wind system with a high pressure centre B) In anticyclone the movement of wind is inward C) The contribution of an anticyclone towards determining weather of an area is quite significant D) The movement of wind is clockwise in an anticyclone of southern hemisphere

Discuss

Answer & Solution

Answer: Option A

Solution:

An anticyclone is a system of winds that rotates around a center of high atmospheric pressure. Distinctive weather patterns tend to be associated with both cyclones and anticyclones.

7

A) Anemometer B) Wind vane C) Wind gauze D) Hygrometer

Discuss

Answer & Solution

Answer: Option B

Solution:

A wind vane is an instrument that determines the direction from which the wind is blowing.

8

Logically, what does a continually rising air pressure indicate?

A) Advent of unsettled and cloudy weather B) Advent of a cyclone C) Fine and settled weather D) Fine and unsettled weather

Discuss

Answer & Solution

Answer: Option A

Solution:

Advent of unsettled and cloudy weather continually indicate rising air pressure.

9

Which one of the following statements is correct?

A) Cirrus clouds are composed of ice crystals B) Cirrus clouds exhibit a flat base and have the appearance of rising domes C) Cumulus clouds are white and thin, and form delicate patches and give a fibrous and feathery appearance D) Cumulus clouds are classified as high clouds

Discuss

Answer & Solution

Answer: Option A

Solution:

The most common form of high-level clouds are thin and often wispy cirrus clouds. Typically found at heights greater than 20,000 feet (6,000 meters), cirrus clouds are composed of ice crystals that originate from the freezing of supercooled water droplets. Cirrus generally occur in fair weather and point in the direction of air movement at their elevation.

10

A fragment of solid matter which enters the upper atmosphere from outer space almost disintegrating before reaching the earth's surface is

A) Meteorite B) Asteroid C) Meteor D) Comet

Discuss

Answer & Solution

Answer: Option C

Solution:

A fragment of solid matter which enters the upper atmosphere from outer space almost disintegrating before reaching the earth's surface is meteor. A meteorite is a solid piece of debris, from such sources as asteroids or comets, that originates in outer space and survives its impact with the Earth's surface. It is called a meteoroid before its impact.
