Weather

The movement of air caused by differences in air pressure is:

• precipitation

• air

• coriolis effect

• jet streams

Air that is cold and dense at the north or south poles create

• high air pressure

• low air pressure

• both of these

• neither of these

Warm, less-dense air at the equator creates

• high air pressure

• low air pressure

• both of these

• neither of these

Due to the earth's rotation, the paths of wind are curved. This is called

• air pressure

• global winds

• coriolis effect

• trade winds

Winds that occur at or near the earth's surface is called

• trade winds

• jet streams

• local streams

• global winds

Narrow belts of high-speed winds are called

• jet streams

• trade winds

• local winds

• sea breezes

Movement of air over short distances are called

• jet streams

• local winds

• global winds

• none of these

Land and sea breezes depends on the

• temperature of land

• temperature of water

• time of day

• all of these

Birds float easily in valley breezes during the day because

• the air flows upward

• the air is cool

• the air flows straight

• the air is strong

The condition of the earth's atmosphere at a certain time and place is called

• temperature

• precipitation

• weather

• visibility
