Key Terms and Ideas in Pressure, Winds, Storms, and Cyclones
These are the terms and ideas the exam asks about most. Learn each one so you can define it and use it in your answers.
| Term / Idea | What it means |
|---|---|
| Pressure | the force acting on a unit area, given by force divided by area |
| Pascal | the SI unit of pressure, equal to one newton per square metre |
| Atmospheric pressure | the pressure exerted by the air around us |
| Wind | moving air that flows from a region of high pressure to a region of low pressure |
| Storm | strong winds accompanied by rain, formed when warm moist air rises |
| Lightning | a bright flash caused by a sudden flow of charges built up in clouds |
| Thunderstorm | a storm accompanied by lightning and thunder |
| Cyclone | a large spinning system of low pressure, high-speed winds and rain over warm ocean waters |
| Eye of the cyclone | the calm central region of lowest pressure in a cyclone |
What the Pressure, Winds, Storms, and Cyclones Handwritten Notes Cover
This chapter builds on forces to explain pressure, which is force spread over an area. It shows that liquids and air both exert pressure, and how differences in air pressure make winds blow. It then explains how storms, thunderstorms, lightning and cyclones form.
- Pressure as force per unit area
- Pressure exerted by liquids
- Atmospheric pressure
- Formation of wind
- High-speed winds and low pressure
- Storms, thunderstorms and lightning
- Formation of cyclones
- Staying safe during lightning and cyclones

Pressure, Winds, Storms, and Cyclones Self-Assessment Quiz
Try these quick questions after you read the notes. Tap each question to check your answer. They cover the points CBSE asks most often.
If a force of 100 N acts on an area of 2 square metre, the pressure is
(a) 200 N per square metre (b) 50 N per square metre (c) 102 N per square metre (d) 98 N per square metre
Answer: (b) 50 N per square metre - pressure is force divided by area, 100 divided by 2
A broad strap on a bag feels more comfortable because it
(a) increases pressure (b) reduces pressure by spreading the weight over a larger area (c) reduces weight (d) adds force
Answer: (b) reduces pressure by spreading the weight over a larger area
Wind blows from a region of
(a) low pressure to high pressure (b) high pressure to low pressure (c) equal pressure (d) no pressure
Answer: (b) high pressure to low pressure - air always moves this way
The calm central region of a cyclone is called the
(a) eye (b) storm (c) edge (d) vector
Answer: (a) eye - it has the lowest pressure and calm winds while the surrounding region is stormy
Lightning is caused by
(a) a sudden flow of charges built up in clouds (b) rain drops (c) warm air only (d) sea water
Answer: (a) a sudden flow of charges built up in clouds - the insulating air breaks down and charges flow
How to Use These Handwritten Notes for Class 8 Science Revision
Use these class 8 science handwritten notes in two passes. Read them slowly once for the full chapter. Then, near the exam, read only the boxes and key terms for a fast recall.
- Read the notes once with the NCERT chapter open beside you.
- Say each key term and idea in your own words.
- Practise one long-answer question from a past paper.
- On the last day, revise only the key terms and the boxes.
