How do you think ocean currents and air masses might interact to produce tropical storms or cyclones?

Multiple Choice

What do you notice about the location of tropical storms? Why do you think they might form in those areas?

• Tropical storms form in warm ocean waters near the equator due to the heat and moisture available.
• Tropical storms occur in polar regions where the air is dry and temperatures are low.
• Tropical storms are common in mountainous regions because of high elevation and wind patterns.
• Tropical storms develop in cold waters far from the equator due to low temperatures.

Multiple Select

Which conditions are necessary for the formation of hurricanes, typhoons, and cyclones?

• Warm ocean water

• Low-pressure center

• Strong winds

• Cold ocean water

Multiple Choice

What is the scientific name for a big spinning storm system with a low-pressure center and strong winds that form over warm ocean water?

• Tropical cyclone

• Thunderstorm

• Tornado

• Monsoon

The only difference between a typhoon, cyclone, and hurricane is the

where the storm formed.

Multiple Choice

Explain the main difference between a typhoon, cyclone, and hurricane.

• They are all the same type of storm.
• Hurricanes occur only in the Southern Hemisphere.
• The main difference is their regional naming: hurricanes (Atlantic), typhoons (Northwest Pacific), and cyclones (South Pacific/Indian Ocean).
• Cyclones are the weakest of the three types.

Tropical

form in the South Pacific and Indian Oceans.

Multiple Choice

What is the main difference between where cyclones and typhoons form?

• Cyclones form in the South Pacific and Indian Oceans, while typhoons form over the Northwest Pacific Ocean.

• Cyclones form over land, while typhoons form over water.

• Cyclones form in the Atlantic Ocean, while typhoons form in the Indian Ocean.

• Cyclones and typhoons form in the same place.

Multiple Select

Which of the following are necessary conditions for the formation of tropical cyclones?

• Warm ocean water

• Cool ocean water

• Presence of land

• Warm air

Multiple Choice

How does the temperature of ocean water affect the strength of tropical storms?

• Warmer ocean water makes storms stronger, while cooler ocean water makes storms weaker.

• Cooler ocean water makes storms stronger, while warmer ocean water makes storms weaker.

• Ocean temperature does not affect storm strength.

• Storms are only affected by wind, not water temperature.

Multiple Choice

Describe two ways tropical cyclones can cause damage when they reach land.

• Tropical cyclones can create clear skies and calm seas.
• They can improve agricultural conditions by providing essential rain.
• Cyclones can enhance tourism by attracting visitors to the coast.
• 1. Strong winds can uproot trees and damage buildings. 2. Flooding from heavy rainfall and storm surges can inundate coastal areas.

Multiple Choice

Explain what happens when a hurricane moves from the ocean to land.

• A hurricane gains strength as it moves onto land due to increased moisture.
• A hurricane remains unchanged when it crosses from ocean to land.
• A hurricane dissipates instantly upon reaching land, causing no damage.
• A hurricane weakens as it moves from the ocean to land due to loss of energy and increased friction.

Multiple Choice

Which of the following best describes the initial step in the formation of a tropical cyclone?

• Warm ocean water heats the air above it, causing the air to rise.

• Cold ocean water cools the air above it, causing the air to sink.

• Strong winds from the land blow over the ocean, creating waves.

• High pressure systems push air downward over the ocean.

Multiple Choice

Explain how the decrease in air pressure contributes to the development of a tropical cyclone.

• High air pressure causes warm air to sink, preventing cyclone formation.
• The decrease in air pressure allows warm, moist air to rise, creating a feedback loop that intensifies the storm and leads to the development of a tropical cyclone.
• Stable air pressure leads to cooler temperatures, inhibiting storm development.
• Increased air pressure allows dry air to dominate, weakening the storm system.

As more warm, humid air is drawn into the system, what happens to the storm? Fill in the blank: The storm gains in size and

, and a tropical cyclone forms.

Multiple Choice

What happens to a hurricane when it makes landfall?

• The air over land is cooler and absorbs all its energy so the hurricane weakens.

• It loses its energy source, which is the warm ocean currents, so the hurricane weakens.

• Once over land, the hurricane’s rainfall increases, gains energy quickly and strengthens.

• The air over the land is warmer and drier causing the hurricane to gain energy and strengthen.

Multiple Choice

What is one condition that is necessary for a hurricane to form?

• Warm ocean water

• A strong cold front

• Cold ocean water

• A strong warm front

Multiple Choice

What questions do you have about the weather forecast shown in the images?

• What is the expected temperature range and are there any severe weather alerts?
• How often is the forecast updated daily?
• Is there a chance of snow this week?
• What time will the rain start and end?

Multiple Choice

Why do tropical cyclones typically form in the tropics?

• Tropical cyclones form mainly in polar regions due to cold ocean currents.
• Tropical cyclones typically develop in deserts where dry air prevails.
• Tropical cyclones are caused by high altitude winds and low humidity levels.
• Tropical cyclones typically form in the tropics due to warm ocean waters and favorable atmospheric conditions.
