Answer: Option C. -> tornado
:
C
A dark funnel shaped cloud that reaches from the sky to the ground is called a tornado.A tornado is a violently rotating column of airthat is in contact with both the surface of the earth and a cloud, orin rare cases, the base of a cloud.

Answer: Option A. -> eye
:
A
The center of thecyclone is known as an eye.The eyeis a region of mostly calm weather which is at the center of strong tropical cyclones.Itis a roughly circular area, typically 30–65 km (20–40 miles) in diameter. Eyeis surrounded by the eyewall, which isa ring of towering thunderstorms where the most severe weather occurs.

Answer: Option C. -> Equator
:
C
The parts near equator receivedirect lightfrom the Sun. So they are heated the most. The equator isan imaginary line drawn around the earth equidistant from both the poles, dividing the earth into northern and southern hemispheres.

Answer: Option C. -> 300 km/hr
:
C
A tornado is a violently rotating column of airthat is in contact with both the surface of the earth and a cloud, orin rare cases, the base of a cloud. It travels at a speed of about 300 km/hr.

Answer: Option C. -> The metal can gets crushed.
:
C
As soon as the water inside the can is heated, water starts converting to water vapour. On sealing the can, the water vapour inside cannot go out and pressure inside the can increases.
When cold water is poured on the can, the water vapour inside the can condenses into water. Thus, there is a drop in air pressure inside the can. The atmospheric pressure then pushes the can inwards, causing it to distort. This can be visualised from the diagram given below.

Answer: Option C. -> more
:
C
The difference in air pressure between two places initiates the movement of air. More the difference in the air pressure, greater will be the speed of movement.Air moves from higher pressure to lowerpressure region.

Answer: Option A. -> satellite
:
A
Satellite images helps us to predict cyclonic path. The use of satellites in disaster management is becoming more integral in reducing reaction time and providing accurate information for rescue and disaster control operations. Satellites are used in disasters for communications, remote sensing and mapping. Meteorological and storm warning satellite technology can help in predicting disasters and setting up precautionary activities.

Answer: Option C. -> Follow the eye of the cyclone.
:
C
In case of a cyclone, one should listen to the warnings issuedby the meteorological department through TV, radio, or newspapers. Driving through waterlogged roads should be avoided, as floods may have damaged the roads. It is safe to stay in the house and not move outside. In case of a cyclone, do not drink river or lake water as the watercan be contaminated, therefore better to store drinking water.

Answer: Option A. -> hurricane
:
A
A cyclone is also called as hurricanein the American continent.
Typhoon is a name for tropical cyclones in Japan regions.
Tornadoes are also circular winds but they are much faster and narrower than cyclones.
Thunderstormisnot a cyclones rather it is astorm with thunder and lightning.

Answer: Option B. -> When there is a pressure difference between the regions.
:
B
The wind blows because of differences in air pressure between the two regions. The wind blows from the regionof high pressure towards the regionof low pressure. The speed of air depends on the difference in air pressure. More the differencemore is the speed of blowing air.
