Question 1
1 / -0

What is a hurricane?

A
Cyclone

B
Earthquake

C
Tornado

D
Thunderstorm

Solution

A hurricane is a type of tropical cyclone, which is a generic term for a low-pressure system that generally forms in the tropics. The cyclone is accompanied by thunderstorms and, in the Northern Hemisphere, a counterclockwise circulation of winds near the earth's surface.
Question 2
1 / -0

What is a cyclone ?

A
A large scale air mass that rotates around a strong centre of low atmospheric pressure.

B
A storm with thunder and lightning and accompanied by heavy rainfall..

C
An overflow of a large amount of water beyond its normal limits

D
A severe snowstorm with high winds

Solution

Explanation: A cyclone is a large scale air mass that rotates around a strong center of low atmospheric pressure, counterclockwise in the Northern Hemisphere and clockwise in the Southern Hemisphere as viewed from above. Cyclones are characterized by inward-spiraling winds that rotate about a zone of low pressure.
Question 3
1 / -0

The centre of the cyclone is also called:

A
Nose of the cyclone

B
Heart of the cyclone

C
Head of the cyclone

D
Eye of the cyclone

Solution

The eye is a region of mostly calm weather at the centre of strong tropical cyclones.
Question 4
1 / -0

Which of the following Indian department provides cyclone warning services?

A
Indian Forest Department

B
Indian Administrative Department

C
Indian Meteorological Department

D
Indian Agricultural Department

Solution

In India, warnings regarding cyclones are issued by the meteorological department through TV, radio, or newspapers.
Question 5
1 / -0

Cyclones are associated with

A
High-speed wind

B
Differential air pressure

C
Uneven heating of land

D
All of the above

Solution

The cyclone is a circulating mass of air that rotates around the center of the low atmospheric pressure region. It is caused due to uneven heating of the land. The uneven heating of land causes the difference in the air pressure and causes the strong flow of wind from high pressure to low pressure regions.
So, the correct answer is option D.
Question 6
1 / -0

Which of the following is most likely to be a characteristic of the 'eye' of a cyclone?

A
It is an area of high pressure

B
It is an area of a low pressure

C
It has lots of clouds and rains

D
It has high speed winds

Solution

The correct answer is option(B).
Eye of a cyclone is a region of mostly calm weather at the center of strong tropical cyclone. It is a roughly circular area. Here the winds are light with minimum barometric pressure, i.e., area of low pressure. Hence, Eye of cyclone is in an area of low pressure.
Question 7
1 / -0

Green revolution in India occurred during -

A
$$1970's$$

B
$$1980's$$

C
$$1950's$$

D
$$1960's$$

Solution
Question 8
1 / -0

The winds on the earth do not blow exactly from "north to south" or from "south to north" directions because:

A
Of the seasons of the earth

B
Of the shape of the earth

C
Of the rotation of the earth

D
All of these

Solution

The rotation of the earth from west to east(pulls) changes the north-south winds to northeast-southwest direction and the south-north winds to southeast-northwest direction.
Question 9
1 / -0

What is a typhoon essentially called as?

A
A flood

B
A cyclone

C
An earthquake

D
A tornado

Solution

A typhoon is basically same thing as a hurricane. Both are tropical cyclone - rapidly rotating storms. If storm form in Northwest Pacific, they are called "Typhoons". Hence, a typhoon is essentially a cyclone.
Question 10
1 / -0

Which of the following plays an important role in the early-warning systems for cyclones?

A
Helicopters

B
Submarines

C
Satellites

D
Stars

Solution

The formation of a very a low-pressure system with very high-speed winds revolving around it is known as a cyclone. Factors like wind speed, wind direction, temperature and humidity contribute to the development of cyclones.
Satellites play an important role in the early-warning systems for cyclones. a
A cyclone alert or Cyclone watch is issued 48 hours in advance of any expected storm and a Cyclone warning is issued $$24\ hours$$ in advance.
