Final Assessment: Winds, Storms and Cyclones

Air Pressure and Wind

Question 1mcq

Cyclones usually form over warm ocean water because:

A.warm moist air rises and creates a low-pressure region.

Question 4mcq

A student says, “Cyclones form equally well over cold dry deserts.” What is wrong?

B.Cyclones are just another name for rusting.

C.Cold deserts contain more warm ocean water than seas.

D.Cyclones need warm moist air, usually from warm seas.

Question 6mcq

Why are coastal areas often at high risk during cyclones?

A.They are always far from water.

B.They are close to strong winds, heavy rain and storm surges from the sea.

C.Cyclones only damage deserts.

D.Coasts have no people or buildings.

Storm Formation

Question 7mcq

Which item is most useful in an emergency kit before a cyclone?

A.Open glass bottles only

B.A metal kite string

C.Torch with batteries

D.Loose roof sheets

Question 8mcq

What should people do if authorities advise evacuation before a severe cyclone?

A.Ignore the warning and go to the beach.

B.Climb onto a weak roof to watch waves.

C.Stand near electric poles.

D.Move to the recommended safe shelter in time.

Question 9mcq

During a storm, why should loose objects outside the house be secured?

A.Strong winds can turn them into dangerous flying objects.

B.They will become heavier and sink into soil.

C.They will stop all rain from falling.

D.They will absorb lightning safely.

Question 10mcq

After a cyclone, which action is safest?

A.Touch fallen wires to check if current is present.

B.Avoid fallen electric wires and wait for official instructions.

C.Drink floodwater if it looks clear.

D.Enter damaged buildings immediately for fun.

Question 11mcq

A student says, “Cyclone safety is needed only after the storm arrives.” What is the best correction?

A.Warnings are useful only after damage occurs.

B.Emergency kits should be made during flooding only.

C.Preparation before the storm is often the most important safety step.

D.Safety has no connection with planning.

Question 12mcq

Which plan is best for a school in a cyclone-prone area?

A.No plan because cyclones are impossible to predict

B.A plan only to decorate classrooms

C.Keeping students outdoors to watch cloud movement

D.Regular drills, safe shelter routes, emergency contacts and weather alert monitoring

Preparedness and Warnings

Question 13mcq

A.Weather satellites

B.Hand lens only

C.Litmus paper

D.A simple balance

Question 14mcq

Why are early cyclone warnings important?

A.They stop all winds instantly.

B.They give people time to prepare, evacuate and protect property.

C.They make cyclones change into rainbows.

D.They are useful only after the cyclone ends.

Question 15mcq

Which information would be most useful in a cyclone warning message?

A.Favourite food of the forecaster

B.Only the colour of the satellite

C.Expected path, wind speed, rainfall risk and safety instructions

D.A list of unrelated chemical symbols

Question 16mcq

A student says, “Forecasts are useless because they may change.” What is the best response?

A.Forecasts are always exactly wrong.

B.Changing forecasts prove weather does not exist.

C.Only old forecasts should be followed.

D.Forecasts can change, but they still help people prepare using the latest information.

Question 17mcq

How do radars help during severe weather?

A.They can track rain clouds and storm movement over a region.

B.They convert wind into electricity in all homes.

C.They measure acidity of rainwater only.

D.They stop lightning from forming.

Question 18mcq

Which community response best uses an early warning?

A.People gather at the beach to watch the storm.

B.Fishermen return to shore and families move to shelters before landfall.

C.Schools ignore alerts because the sky is still clear.

D.Everyone waits until floodwater enters homes.

Pressure Reasoning

Question 19mcq

If air pressure is lower over a heated area than a nearby cooler area, what is likely to happen?

A.Air moves only from low pressure to high pressure.

B.No air movement can occur.

C.Air from the cooler high-pressure area moves toward the heated low-pressure area.

D.The heated area immediately becomes ice.

Question 20mcq

A paper strip rises when air is blown fast over its top surface. Which idea helps explain this?

A.Air pressure increases only when air is invisible.

B.Paper rises because it becomes magnetic.

C.Moving air has no effect on pressure.

D.Fast-moving air can have lower pressure than stiller air nearby.

Question 21mcq

Two towns are at the same height. Town A is much warmer than Town B in the afternoon. Which explanation for wind is most reasonable?

A.Air rises over warmer Town A, creating lower pressure that draws air from Town B.

B.Air sinks over Town A and blocks all wind.

C.Town B must have no air at all.

D.Temperature differences cannot affect air movement.

Question 22mcq

Why does a strong pressure difference usually produce stronger winds?

A.Pressure difference makes air disappear.

B.A larger pressure difference pushes air more strongly.

C.Strong winds need no pressure difference.

D.Only rainfall controls wind speed.

Question 23mcq

Assertion: Uneven heating of Earth can produce winds. Reason: Uneven heating creates pressure differences in air. Which option is correct?

A.Both are true, but the reason does not explain the assertion.

B.The assertion is true, but the reason is false.

C.Both assertion and reason are true, and the reason explains the assertion.

D.The assertion is false, but the reason is true.

A.The door changed into a magnet.

B.Air has no pressure in corridors.

C.The corridor removed gravity.

D.Moving air created pressure differences around the door.
