- 1. Multiple Choice
What is the primary energy source that fuels tropical cyclones?
Solar radiation
Warm ocean water
Wind currents
Earth's rotation
- 2. Multiple Choice
Which of the following is NOT a necessary condition for the formation of a tropical cyclone?
Warm ocean temperatures
High wind shear
Moist air
Low-pressure area
- 3. Multiple Choice
What role do ocean currents play in the development of tropical cyclones?
They cool the ocean surface, preventing cyclone formation.
They transport warm water, providing energy for cyclones.
They create high-pressure systems that dissipate (break down) cyclones.
They have no effect on cyclones.
- 4. Multiple Choice
How do air masses contribute to the formation of tropical cyclones?
By creating high-pressure zones
By providing moisture and heat
By increasing wind speed
By cooling the ocean surface
- 5. Multiple Choice
What is the Coriolis effect's role in tropical cyclones?
It strengthens the cyclone's winds.
It causes the cyclone to rotate.
It dissipates (breaks down) the cyclone.
It has no effect on cyclones.
- 6. Multiple Choice
Which oceanic region is most likely to produce typhoons?
North Atlantic Ocean
South Atlantic Ocean
Western Pacific Ocean
Indian Ocean
- 7. Multiple Choice
What is the minimum sea surface temperature generally required for tropical cyclone formation?
- 8. Multiple Choice
Which of the following best describes the eye of a tropical cyclone?
A region of high winds and heavy rain
A calm and clear area at the center
The most destructive part of the cyclone
The outermost part of the cyclone
- 9. Multiple Choice
What happens to a tropical cyclone when it moves over land?
It gains strength due to increased friction.
It weakens due to lack of moisture and heat.
It remains unchanged.
It splits into smaller storms.
- 10. Multiple Choice
Which of the following factors can lead to the dissipation (break down) of a tropical cyclone?
Moving over warm ocean waters
Encountering high wind shear
Increasing in size
Moving towards the equator
- 11. Multiple Choice
Which is the most likely cause of tropical storms?
Water runoff from the land fuels storm clouds.
High-pressure air causes storm clouds to form.
Sea breezes close to shore push storm clouds together.
Warm water evaporates, rises quickly, and interacts with a colder air mass.
- 12. Multiple Choice
When fronts are distorted by surface features like mountains, or the jet stream, or the Coriolis effect, the air begins to SWIRL and a LOW PRESSURE center forms. This weather event is known as a cyclone, or in the Northern Hemisphere, we call it a(n) _______ when winds blow faster than 119 km/h.
anticyclone
hurricane
whirlpool
- 13. Multiple Choice

cold front
- 15. Multiple Choice
A front is
where warm air is cooling at earth's surface
a line where hot and cold air are separating
a line where two different air masses meet
where cold air is rising and forming rain clouds
- 16. Multiple Choice

- 23. Multiple Choice
A scientist is studying how hurricanes form and how they might be affected by climate change. Which of the following models best explains the formation of a hurricane and predicts how rising ocean temperatures due to climate change might impact hurricanes?
A. Hurricanes form when warm ocean waters evaporate rapidly, creating high-pressure systems that stabilize the storm. .
B. Hurricanes form when warm, moist air rises over warm ocean waters, creating a low-pressure system, which is then intensified by the Coriolis effect.
C. Hurricanes form from warm ocean waters. Rising ocean temperatures would decrease hurricane intensity due to reduced wind shear.
D. Hurricanes form when cold ocean currents interact with high-pressure systems, creating intense storms.
- 24. Multiple Choice
A meteorologist is studying weather patterns associated with different types of weather fronts. Based on your understanding of weather systems, which of the following scenarios most accurately models the type of weather that occurs after a cold front and justifies the pattern observed?
A. After a cold front passes, the temperature drops significantly, skies become clearer, and there is an increase in atmospheric pressure due to the arrival of cooler, denser air. This is because cold air displaces warm air rapidly.
B. After a cold front passes, the temperature rises quickly, skies remain cloudy, and atmospheric pressure decreases due to the continued presence of warm, moist air being pushed aloft.
C. After a warm front passes, the temperature drops slightly, rain persists for several days, and atmospheric pressure fluctuates due to slow-moving cold air overtaking the region.
D. After a warm front passes, the temperature rises gradually, skies clear quickly, and atmospheric pressure remains low due to the stable presence of warm air masses.
- 25. Multiple Choice
Major surface currents of the ocean are shown in the diagram.
Ocean currents affect weather patterns by -
regulating when tides occur in coastal areas
trapping heat at the equator to regulate the global climate
distributing heat from the uneven absorption of solar energy
increasing the rate of evaporation to transport water to areas experiencing droughts
