Local Winds

What causes wind?

• differences in air pressure

• differences in gravity

• difference in oxygen

• differences in the thermosphere

What causes differences in air pressure?

• even heating of the Earth

• Even cooling of the earth

• uneven heating of the earth

• global warming

Local winds blow over:

• short distances

• long distances

• the poles

• the equator

Flow of air from land to a body of water is called:

• doldrum

• chinook

• sea breeze

• land breeze

• during the day

• during the night

• high noon

• full moon

Which is NOT a characteristic of local winds?

• They occur within a small area.
• Land and sea breezes are examples.
• They blow over short distances.
• They blow steadily over long distances.

What kind of air pressure does COLD air have?

• High pressure
• Low pressure

What kind of air pressure does WARM air have?

• High pressure
• Low pressure

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

• Land breeze
• Sea breeze

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

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