Chapter 6 Pressure, winds, storms and Cyclones

CBSE Notes Class 8 Science Chapter 6 Pressure, Winds, Storms and Cyclones

Air exerts pressure, and differences in air pressure lead to the movement of air, which we experience as wind. This chapter explains how pressure affects weather and causes natural phenomena like storms and cyclones. Students learn about atmospheric pressure and how it changes with altitude and temperature.

This CBSE Class 8 Science chapter explains how winds are formed due to differences in air pressure. It also covers natural disasters like cyclones, their formation, and safety measures to reduce damage. This chapter helps students understand weather patterns and the importance of disaster preparedness.

Frequently Asked Questions

Pressure is the amount of force per square foot: P = F/A​P = AF. For example, a sharp knife cuts better because it has a smaller area and more pressure.

Wind happens when air moves from places with high pressure to places with low pressure because the heating is uneven. Sunlight warms land faster than water, which causes pressure differences.

When air gets warmer, it expands, becomes less dense, and rises above cooler, denser air. This convection current moves the ocean and the weather.

A cyclone is a strong storm with winds that move quickly around a low-pressure eye. It forms over warm oceans and brings heavy rain and destruction.

When the wind blows quickly over the roof, it makes the air pressure inside push the roof up. Bernoulli's principle says that faster air flow lowers pressure above the surface.
