Typhoon

Multiple Choice

Which of the following best describes a typhoon?

• A powerful tropical cyclone that forms over warm ocean waters in the Western Pacific Ocean

• A small storm system that forms over land

• A snowstorm that occurs in polar regions

• A tornado that forms in the Midwest United States

Multiple Choice

Why do you think typhoons are significant to study in regions near the Western Pacific Ocean?

• Because the region experiences many typhoons.

• Because typhoons rarely occur there.

• Because typhoons have no impact on communities.

• Because the region controls global weather.

Multiple Choice

Where do hurricanes, cyclones, and typhoons form?

• Hurricanes form in the Atlantic or Northeast Pacific, cyclones in the Indian Ocean, and typhoons in the Northwest Pacific.

• Hurricanes form in the Indian Ocean, cyclones in the Atlantic, and typhoons in the Arctic.

• All three form only in the Atlantic Ocean.

• Typhoons form in the Atlantic, hurricanes in the Northwest Pacific, and cyclones in the Indian Ocean.

Multiple Choice

Which sequence best describes the formation of a typhoon?

• Cool air sinks over warm ocean water, creating calm winds → clouds disperse → a vortex forms from cold fronts.

• Warm, moist air rises from the ocean surface → air begins to rotate due to wind shear and the Earth’s rotation → the rotation strengthens, forming a violent spiraling system.

• Dry air from land moves over the ocean → condensation rapidly cools the sea surface → a spiral cloud tower forms instantly.

• Ocean water cools to below 20°C → winds slow down → clouds compress into a rotating storm.
