Open Ended

But where does that wind come from?

Multiple Choice

Which of the following statements best explains why warm air rises?

• Warm air is less dense than cool air.

• Warm air is heavier than cool air.

• Warm air is pushed up by cool air.

• Warm air is attracted to the sun.

Multiple Choice

What happens to air pressure when air rises?

• It increases

• It decreases

• It stays the same

• It becomes zero

Multiple Select

Select all the correct statements about cool air and air pressure.

• Cool air is dense and sinks.

• Cool air creates high pressure.

• Cool air rises quickly.

• Cool air creates low pressure.

Fill in the Blanks

Sinking air presses down with more force, so the air pressure is

.

Multiple Choice

What is atmospheric pressure?

• The measure of how strongly Earth's atmosphere pushes down on a given area.

• The amount of water vapor in the air.

• The temperature of the air at sea level.

• The speed of wind in the atmosphere.

Open Ended

Explain the relationship between air pressure, temperature, and the movement of air as shown in the diagrams.

Multiple Choice

How does the movement of air between high and low pressure areas cause wind?

• Air moves from high pressure to low pressure, creating wind.

• Air moves from low pressure to high pressure, creating wind.

• Wind is caused by the rotation of the Earth only.

• Wind is caused by the sun heating the ground directly.

Fill in the Blanks

Wind is the

of air across Earth's surface.

Open Ended

Describe some examples of 'happy' weather and 'lousy' weather based on what you have learned about pressure systems.

Multiple Select

Which of the following statements are correct about high and low pressure systems?

• High pressure is associated with happy weather.

• Low pressure is associated with lousy weather.

• High pressure is associated with lousy weather.

• Low pressure is associated with happy weather.

Multiple Choice

What happens to warm air at the equator, and how does this affect air pressure?

• It rises and creates low air pressure.

• It sinks and creates high air pressure.

• It stays at the surface and creates high air pressure.

• It cools and creates low air pressure.

Open Ended

Describe the process that causes air to sink back to Earth's surface at different latitudes.

Fill in the Blanks

Winds form as air moves from areas of ___ pressure to areas of ___ pressure.

Multiple Choice

Which of the following best explains why wind can occur on both small and global scales?

• Because of the uneven heating of Earth by solar energy.

• Because the Earth is flat.

• Because the air pressure is always the same everywhere.

• Because the sun only heats the equator.

Multiple Choice

If Earth did not rotate, how would winds move between the poles and the equator?

• In straight lines

• In curves

• In circles

• They would not move

Open Ended

Explain how Earth's rotation affects the direction of global wind patterns.

Multiple Choice

What is the main effect of Earth's rotation on global winds?

• It causes winds to blow in a straight line from poles to equator.

• It causes global winds to curve, creating wind belts.

• It increases the speed of global winds.

• It stops the formation of wind belts.

Open Ended

Explain how wind belts are formed and what determines their location on Earth.

Multiple Choice

Which of the following statements about jet streams is correct?

• Jet streams are slow-moving winds near the surface.

• Jet streams flow from east to west.

• Jet streams are narrow bands of high-speed winds in the atmosphere.

• Jet streams form only at the equator.

Fill in the Blanks

Jet streams form when warm air masses meet cold air masses in the

.

Open Ended

How does uneven heating of Earth contribute to the formation of global wind patterns?

Multiple Select

Select all the correct statements about global wind patterns.

• Winds blow from areas of high pressure to low pressure.

• Global winds curve due to the Coriolis effect.

• Jet streams flow from east to west.

• Wind belts are groups of winds that occur between certain latitudes.

Multiple Choice

What is the relationship between El Niño and La Niña?

• They have no relationship

• El Niño and La Niña are the same phenomenon

• El Niño and La Niña are opposite phases of a cycle

• El Niño and La Niña occur simultaneously

Multiple Choice

The El Nino will cause what kind of weather in the southern US?

• cold and dry
• cold and wet
• warm and wet
• warm and dry

Multiple Choice

What causes La Nina?

• cooling of water in the Atlantic Ocean off the coast of South America
• cooling water off the Atlantic coast of the US
• cooling water in the Pacific Ocean off the coast of South America
• warm water in the Pacific Ocean off the coast of South America
