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
