Class 7 Science Chapter 8 Winds Storms And Cyclones Summary
Causes of Winds
- Uneven heating of the Earth’s surface
- Rotation of the Earth (Coriolis effect)
- Differences in air pressure
Types of Winds
- Sea breeze and land breeze
- Monsoon winds
- Trade winds
Thunderstorms
- Caused by rising warm, humid air
- Involve lightning, thunder, and heavy rainfall
Cyclones
- Low-pressure systems with spiraling high-speed winds
- Develop over tropical seas and can cause widespread destruction
- Known as hurricanes in the Americas and typhoons in Asia
- Factors like temperature, humidity, and wind direction contribute to their formation
Destruction Caused by Cyclones
- Strong winds push water towards the shore, causing flooding
- Low pressure in the eye can lift the water surface by several meters
- Seawater enters low-lying coastal areas, leading to loss of life and property
Safety Measures for Cyclones
- Advance warning systems and evacuation plans
- Strengthening infrastructure in coastal areas
- Planting mangroves and other vegetation to act as natural barriers
