Pressure Winds Storms and Cyclones Class 8 Short Question Answer

Question 1.

How do thunderstorms form?

Answer:

Thunderstorms form when warm, moist air rises rapidly, cools, and condenses to form clouds, leading to the development of clouds, which can produce heavy rain, thunder, and lightning.

Question 2.

What is the difference between a cyclone and a thunderstorm?

Answer:

A cyclone is a large-scale weather system characterised by low pressure and strong winds that rotate around a centre, while a thunderstorm is a localised weather event that produces thunder, lightning, and heavy rain, typically lasting for a shorter duration.

Question 3.

What is the relationship between pressure, force, and area?

Answer:

Pressure is defined as the force exerted per unit area, expressed mathematically as

Pressure =[latex]\frac{\text { Force }}{\text { Area }}[/latex]

This means that for a given force, increasing the area over which it is applied will decrease the pressure, and vice-versa.

Question 4.

How do storms develop into cyclones?

Answer:

Storms can develop into cyclones when warm, moist air rises and creates low pressure at the surface, causing surrounding air to rush in and form a rotating system. This process is fuelled by the heat from the ocean, which intensifies the storm and can lead to the formation of a cyclone.
