Question 1
1 / -0

The instrument that measures the wind speed is called an ____________ .

A
thermometer

B
anemometer

C
seismograph

D
ammeter

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

How do cyclones decrease the fertility of the soil in the coastal areas?

A
By flooding the land with saline water

B
By dissolving soil and rocks

C
By increasing the water table of the place

D
By decreasing the water table of the place

Solution

In coastal areas, cyclones exert a great force on seawater due to this, saline seawater floods the land in coastal areas. This saline water decreases the fertility of the land.
Question 3
1 / -0

Which of the following is the first sign of an approaching cyclone?

A
Rains accompanied by lighting

B
High temperature and humidity

C
Cool breeze and rains

D
Powerful water waves

Solution

The first signs of the storm appear. The barometer is falling slightly, the wind is around $5\ ms^{-1}$ , and the ocean swell is about $4\ m$ in height and coming $7\ s$ apart.
Question 4
1 / -0

A typhoon is essentially

A
a flood

B
a cyclone

C
earthquake

D
none of these

Solution

A cyclone is known by different names in different parts of the world. It is called a ‘hurricane’ in the American continent. In Philippines and Japan it
is called a ‘typhoon’.
Question 5
1 / -0

Which of the following is a anemometer?

A

B

C

D

Solution

An anemometer is a device used for measuring wind speed and direction. It is a common weather station instrument. The image of the anemometer is given in option (C).
Question 6
1 / -0

Anemometer is a ___________ instrument.

A
light emitting

B
wind speed measuring

C
sound producing

D
reflecting

Solution

An anemometer is a device used for measuring wind speed and direction. It is a common weather station instrument. The term is derived from the Greek word 'anemos', which means wind, and is used to measure the wind speed in meteorology.
Question 7
1 / -0

A
Wind speed

B
Distance

C
Area

D
Water speed

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 8
1 / -0

Which of the following is/are true?

A
The wind blows because of differences in air pressure from one location to another

B
Wind blows from areas of high pressure toward areas of low pressure

C
If the high pressure area is very close to the low pressure area, or if the pressure difference is very great, the wind can blow very fast

D
All of the above

Solution

Blow of wind is the result of pressure difference in the air between two regions. The wind blows from the region of higher pressure to the region of lower pressure. Greater is the pressure difference, greater is the speed of the wind blowing, and vice-versa.
Thus all the statemements are true, so option D is correct.
Question 9
1 / -0

What are the precautions one must take when one is in a cyclone-hit area ?

A
Not drink contaminated water. Store and use drinking water effectively.

B
