Why are there fewer molecules of air up in the mountains? (Pressure forces the air molecules nearer to Earth's surface, so more air is located closer to Earth.)

• because air pressure increases as you go higher

• because air pressure is the same throughout all layers of the atmosphere

• because air is too heavy

• because air pressure decreases as you go higher

Weather refers to the state of the atmosphere__________. (Weather includes conditions such as air pressure, wind temperature, and the amount of moisture in the air.)

• over a long period of time

• at a specific time and place

• at a specific temperature

• over a short period of time

How do isobars help meteorologists predict weather? (An isobar is a line drawn on a weather map to connect points of equal atmospheric pressure.)

• They help meteorologists see areas of equal temperature.

• They help meteorologists predict dry weather.

• They help meteorologists tell how fast wind is blowing by noting the distance between the isobars on a weather map.

• They help meteorologists determine the daily temperature and wind direction.

Force exerted on an area is called __________. (Gravity is the force that pulls mass toward Earth's center.)

• temperature

• gravity

• pressure

• mass

Why are these two systems showing how wind is formed? (Dense, cool air sinks, while less dense warm air rises.)

• They show the rotation of Earth

• They show how differences in air pressure produce air movement.

• The show downdrafts during hurricanes.

• They show the clockwise motion of air during storms.

What is the cause of the strong winds associated with thunderstorms? (Thunderstorms are accompanied by large raindrops that cool the air around them.)

• weak updrafts of warm, moist air

• strong updrafts of dry air

• rain-cooled air

• strong updrafts of warm, moist air and downdrafts of rain-cooled air
