________ is the force exerted on an object by the weight of the air above and around it.

• Wind pressure

• Air pressure

• Temperate weight

• high pressure air

What is the name of the instrument used to measure air pressure?

• Precipitation

• Clouds

• Wind

What causes differences in air pressure?

• wind

• rain

• snow

• solar radiation

This is when the rotation of the Earth affects the direction of the wind.

• convergent effect

• marginal effect

• Coriolis effect

At the equator the air is usually ________.

• rising
• sinking

At the poles, air is usually ________.

• rising
• sinking

In what direction(s) does air exert pressure?

• everywhere
• no where
• there is no pressure
• downward

Earth has a low air pressure zone at the equator because

• air is cold and sinks toward the surface of Earth there

• air is cold and moves away from the surface of the Earth there

• air is warm and moves away from the surface of the Earth there

• air is warm and moves toward from the surface of the Earth there

Earth has a high air pressure zone at the north pole because

• air is cold and sinks toward the surface of Earth there

• air is cold and moves away from the Earth there

• air is warm and moves away from the surface of the Earth there

• air is warm and sinks toward the surface of Earth there
