Question 1
1 / -0

An anemometer is an instrument that is most similar to a :

A
Accelerator

B
Speedometer

C
Flag

D
Electric meter

Solution

An anemometer is a device used for measuring wind speed and direction. It is also a common weather station instrument. The term is derived from the Greek word anemos, which means wind, and is used to describe any wind speed instrument used in meteorology.
Question 2
1 / -0

Consider the following statements:
1. All cyclones develop an eye at the center.
2. The temperature inside the eye is nearly $$10^\circ C$$ lesser than that of the surroundings.
Which of the statements given above is/are correct?

A
1 only

B
2 only

C
Both 1 and 2

D
Neither 1 nor 2

Solution

At the centre of a cyclone is an area of calm called the eye. The eye is usually about $$40\ km$$ in diameter. Air in the centre of a cyclone is less dense than the air around it because the temperature inside the eye is greater than that of the surroundings.
Question 3
1 / -0

State true or false.
It is safe to use telephone during a thunderstorm.

A
True

B
False

C
Ambigious

D
Data insufficient
Question 4
1 / -0

What is likely to happen if high speed winds blew over a building with a weak roof?

A
Roof will collapse

B
Roof will be blown away

C
Roof will be unaffected

D
Either A or B

Solution

High speed winds right outside the building will create a low pressure region around it. As we know that air flows from higher pressure to lower pressure, it is likely that the roof will be blown away.
Question 5
1 / -0

At what time during a 24-hour day would a radiation temperature inversion best be developed?

A
At sunset

B
Near sunrise

C
Toward the end of the morning

D
Between 2 and 5 pm when the air temperature reaches a maximum

Solution
Question 6
1 / -0

A house or building is the safest place during a thunderstorm.

A
True

B
False

C
Ambigious

D
Data insufficient

Solution

During thunderstorm , lightning always strikes in an open area .That's why staying inside the house is considered safe during thunderstorm.
Question 7
1 / -0

Low atmospheric pressure exists on the Earth in which of the following latitudes?

A
At the equator only

B
At $$30^{\circ}$$ North pole and South pole

C
At the pole

D
At the equator and at $$60^{\circ}$$ North pole and South pole

Solution

The low atmospheric pressure exists at the to N and S region of the equator of the earth. This region is called the subpolar region.
Question 8
1 / -0

Consider the following statements:
A: During storms, all windows should be tightly shut
B: During storms, the air pressure outside a house is less than air pressure inside the house

A
Both A and B are correct

B
A is correct and B is incorrect

C
A is incorrect and B is correct

D
Both A and B are incorrect

Solution

We know that increased wind speed is, indeed, accompanied by reduced air pressure. As the wind speed is higher outside the house the air pressure would be lesser outside. In such cases, there is a risk of the roof getting blown away, if not constructed properly. That's why it's advisable not to close all the windows of a house with poorly constructed roofs, during a storm.
Question 9
1 / -0

Which of the following statements is/are correct?
1. The tropical cyclones of China Sea are called typhoons.
2. The tropical cyclones of the West Indies are called tornadoes.
3. The tropical cyclones of Australia are called willy willies.
4. Formation of an anticyclone results in stormy weather condition.
Select the correct answer using the code given below:

A
1, 2, 3 and 4

B
1, 2 and 4 only

C
1 and 3 only

D
3 only

Solution

A typhoon is the name of a strong tropical cyclone whose development is common in the Western North Pacific Ocean and South China Sea.
The vast majority of tornadoes occur in the Tornado Alley region of the United States although they can occur nearly anywhere in North America.
Willy Willies is a severe tropical cyclone of Australia.
Formation of an anticyclone may or may not result in stormy weather condition depending on it's origin.
Question 10
1 / -0

Choose the correct statement from the following.

A
High speed winds are accompanied by reduced air
pressure.

B
High speed winds are accompanied by increased air
pressure.

C
Change in pressure does not affect the wind velocity.

D
Humidity can change the velocity and direction of wind.
