Earth's wind

What is responsible for warming the Earth’s surface and creating wind?

• The Moon
• Earth's interior (inside)
• Coriolis effect
• The Sun

What causes wind?

• differences in air pressure

• differences in gravity

• difference in oxygen

• differences in the thermosphere

What causes wind to blow?

• Differences in longitude 
• Shock waves from clouds 
• Differences in air temperature and pressure 
• The rotation of the earth

.    _____ is caused by the difference between high and low pressure areas.     

• High Pressure

• Low Pressure

• Wind

• Jet Stream

During the day, warm air rises over the land then cools and falls over water in a continuous cycle.

• Land breeze
• Sea breeze

Which statement correctly defines wind?

• Wind is the movement of air from areas of low pressure to areas of high pressure
• Wind is the movement of air to a colder area in the atmosphere.
• Wind is the movement of air from areas of high pressure to areas of low pressure.
• Wind is the movement of air pushed around and bouncing off Earth's surface.

Why does warm air rise?

• Warm air is more dense than cooler air.
• Warm air has more pressure than cooler air.
• Warm air is less dense than cooler air.
• Warm air has a higher dew point than cooler air.

Which best describes why winds at the beach change direction between day and night? **

• because the temperatures over land and over water change 
• because warm air over land sinks and stays in place over land
• because cool air rises and is replaced by warm air from the ocean 
• because cool air sinks and stays in place over land 

What creates the air pressure difference between the equator and the poles?

• The length of the seasons.
• The shape of the earth.
• More elephants pass gas near the equator.
• The amount of direct sunlight each area receives.

Wind blows from ______ pressure areas to _____ pressure areas.

• high; low
• warm; cool
• cool; warm
• low; high
