Describe what is likely to immediately happen in the scene below.

The cool, dense air mass will fall to the ground. The warmer, less dense air mass will rise.

True or False: When air heats up, its volume increases but its mass stays exactly the same.

True

What does a barometer measure and how does it work?

A barometer measures changes in atmospheric pressure. The higher the pressure in the atmosphere, the higher the liquid in the barometer will rise. If there is less atmospheric pressure, the liquid will fall.

If a mass of warm air cools down, what will happen to its volume and density?

(a) Its volume will decrease and its density will increase.

What would happen if the temperature of the air mass shown below increased to 30°C?

(a) The air would rise, creating a low pressure zone on the Earth's Surface.

Which graph shows what happens to the temperature of the troposphere as the distance from the surface of the Earth increases?

(b)

Which BEST describes what causes wind?

(b) Differences between areas of high pressure and low pressure in the atmosphere.

Dense air pressing down on the Earth's surface will likely create what?

(b) High Pressure

What direction is the warm air front moving on the map below? {insert image here}

(b) South

Examine the map of Pennsylvania below. What is most likely to happen?

(c) Air from zone B will flow into C.

Look at the weather map. Which of the statements below is true?

(c) Area C will have the strongest

As the temperature of a gas increases, what will also increase?

(c) The gas's volume

What is the relationship between the temperature of air and its density?

(c) When air temperature increases, the density decreases.

If air mass B in the picture below suddenly rises, what will happen?

(d) Air mass A and C will move closer together

What factors are necessary for precipitation to form along fronts?

(d) All of the above

Which zone on the map below represents the lowest pressure zone?

(d) Zone D

True or False: A decrease in density as air is heated causes it to rise above cooler, more dense.

True

True or False: Atmospheric pressure will change as a front moves across an area.

True
