Pressure, Winds, Storms and Cyclones — important questions & MCQs with answers (Class 8 Science)
14 solved questions from this chapter's difficulty levels, each with its answer and explanation.
- Q1Easy
Pressure is defined as:
A.force per unit area✓ CorrectB.force × areaC.force + areaD.area per unit forceAnswer: A. force per unit area
Explanation: Pressure = Force ÷ Area — it measures how concentrated a force is over a surface, not force times area or force plus area.
- Q2Easy
The pressure exerted by the air around us is called:
A.water pressureB.muscular pressureC.atmospheric pressure✓ CorrectD.chargeAnswer: C. atmospheric pressure
Explanation: The pressure the surrounding air exerts on everything is called atmospheric pressure, distinct from pressure from water or muscles.
- Q3Easy
The two main requirements for a thunderstorm are:
A.cold, dry airB.moisture and strong winds✓ CorrectC.only sunlightD.completely calm airAnswer: B. moisture and strong winds
Explanation: Thunderstorms need plenty of moisture to form clouds and strong winds to build up electric charge — cold, dry, calm air cannot produce one.
- Q4Easy
A cyclone is a:
A.gentle breezeB.type of rainbowC.large, violent storm with very strong winds✓ CorrectD.cloud shape onlyAnswer: C. large, violent storm with very strong winds
Explanation: A cyclone is a large, violent storm system with very strong winds and heavy rain, not a mild breeze or a cloud shape.
- Q5Easy
The formula for pressure is:
A.Pressure = Force × AreaB.Pressure = Force ÷ Area✓ CorrectC.Pressure = Area ÷ ForceD.Pressure = Force + AreaAnswer: B. Pressure = Force ÷ Area
Explanation: Pressure = Force ÷ Area (P = F ÷ A), not force multiplied by area — multiplying would grow with size instead of measuring concentration.
- Q6Easy
Air moves from a region of:
A.low pressure to high pressureB.high pressure to low pressure✓ CorrectC.equal to equal pressureD.no pressure to no pressureAnswer: B. high pressure to low pressure
Explanation: Air always flows from a high-pressure region toward a low-pressure one, the same way water flows downhill — this flow is what we feel as wind.
- Q7Medium
A force of 20 N acts on an area of 4 m². The pressure is:
A.5 Pa✓ CorrectB.80 PaC.24 PaD.16 PaAnswer: A. 5 Pa
Explanation: Pressure = Force ÷ Area = 20 N ÷ 4 m² = 5 Pa.
- Q8Medium
During the day, the land heats up faster than the sea, so the wind blows:
A.from the land to the seaB.straight upC.not at allD.from the sea to the land (sea breeze)✓ CorrectAnswer: D. from the sea to the land (sea breeze)
Explanation: The land heats up faster, so warm air over land rises and creates low pressure there; cooler air from the higher-pressure sea flows in as a sea breeze.
- Q9Medium
In a thundercloud, electric charges build up because strong winds cause:
A.the Sun to shineB.ice particles and water droplets to rub together✓ CorrectC.the ground to shakeD.fires to startAnswer: B. ice particles and water droplets to rub together
Explanation: Strong up-and-down winds inside a thundercloud make ice particles and water droplets collide and rub together, building up separated electric charges.
- Q10Medium
Under certain conditions, a strong storm may develop into a:
A.rainbowB.calm dayC.cyclone✓ CorrectD.desertAnswer: C. cyclone
Explanation: Under the right conditions of warmth and moisture over the sea, a strong storm can intensify further into a full cyclone.
- Q11Medium
A force of 100 N acts on 10 m². The pressure is:
A.1000 PaB.10 Pa✓ CorrectC.110 PaD.90 PaAnswer: B. 10 Pa
Explanation: Pressure = Force ÷ Area = 100 N ÷ 10 m² = 10 Pa.
- Q12Hard
The same person stands first on one foot, then on two feet. The pressure on the floor is:
A.greater on two feetB.greater when standing on one foot✓ CorrectC.the same either wayD.zero on one footAnswer: B. greater when standing on one foot
Explanation: Standing on one foot puts the same body weight on half the contact area, so pressure = force ÷ area is greater on one foot than on two.
- Q13Hard
Winds ultimately blow because the Sun heats the Earth:
A.evenly everywhereB.only at nightC.not at allD.unevenly, creating pressure differences✓ CorrectAnswer: D. unevenly, creating pressure differences
Explanation: The Sun heats different parts of Earth's surface unevenly, creating regions of unequal air pressure, and air flowing from high to low pressure is wind.
- Q14Hard
Strong winds during a thunderstorm move both upward and downward, which helps to:
A.cool the SunB.build up electric charges in the clouds✓ CorrectC.stop the rainD.create sunlightAnswer: B. build up electric charges in the clouds
Explanation: Winds moving both upward and downward inside a thundercloud make ice and water particles collide repeatedly, which is how electric charge builds up.
Key concepts: Pressure, Winds, Storms and Cyclones (Class 8 Science)
This chapter connects a simple idea — pressure — to the weather. Pressure is the force acting on each unit of area (Pressure = Force ÷ Area), measured in pascals (1 Pa = 1 N/m²), so the same force on a smaller area gives a higher pressure. Air presses on everything as atmospheric pressure, and differences in air pressure make winds blow from high-pressure to low-pressure regions. Warm air rises to create low pressure that cooler air rushes in to fill — the engine behind breezes, thunderstorms with lightning, and powerful cyclones, against which we protect ourselves using lightning conductors and IMD warnings.
- Pressure
- The force acting on each unit of area, given by Pressure = Force ÷ Area. Its SI unit is the pascal (Pa), equal to one newton per square metre.
- Pressure and area
- For the same force, a smaller area gives a higher pressure (a sharp knife, a nail tip) and a larger area gives a lower pressure (wide straps, camel feet, tractor tyres).
- Pressure by liquids and gases
- Liquids and gases exert pressure in all directions on the walls of their container; a liquid also settles at the same level in connected vessels.
- Atmospheric pressure
- The pressure exerted by the air around us; it holds a rubber sucker onto a smooth surface and decreases as you go higher up.
- Wind
- Moving air. Wind blows from a region of high pressure to a region of low pressure, and a bigger pressure difference gives a stronger wind.
- Warm air rises
- Heated air expands, becomes lighter and rises, leaving a low-pressure area that cooler, denser air from higher-pressure surroundings moves in to fill.
- Sea and land breezes
- By day the land heats faster, so cooler sea air blows in as a sea breeze; by night the land cools faster and a land breeze blows out to sea.
- Thunderstorms
- Form where there is moisture and strong winds; rising, cooling vapour condenses into clouds, and rubbing ice and water droplets build up electric charges.
- Lightning and its conductor
- Lightning is the discharge when positive and negative charges meet, within a cloud, between clouds or between a cloud and the ground; a lightning conductor safely carries it to the earth.
- Cyclones
- Violent storms that form over warm seas as warm air rises and cool air rushes in; they cause flooding, salt-damaged farmland, blocked roads and power cuts.
- Cyclone safety
- Weather satellites and the India Meteorological Department (IMD) track cyclones and issue warnings; people should keep an emergency kit and move to a cyclone shelter.
