Jason lives in Denver, Colorado, at an altitude of over 5,000 feet above sea level. Molly lives in Jacksonville, Florida, which has an altitude of just 40 feet above sea level.
How does the air pressure in Denver differ from the air pressure in Jacksonville?
A
The air pressure is much higher in Jacksonville because it is closer to the equator.
B
The air pressure is much lower in Denver because air pressure decreases as altitude increases.
C
The air pressure is much lower in Jacksonville because air pressure increases as altitude increases.
D
The air pressure is the same in both cities because air pressure is equal at altitudes greater than 25 feet above sea level.
B
The air pressure is much lower in Denver because air pressure decreases as altitude increases.

Mr. Sanchez’s class is studying the movement of the planets and their moons. A student makes the model shown with objects representing the sun, Earth, and the moon to use in a class demonstration.
Which action should the student do with the objects to demonstrate a complete day-night cycle of Earth?
A:Spin Earth in a circle once.
B:Spin the Sun in a circle once.
C:Move Earth around the Sun once.
D:Move the Moon around Earth once.
A:Spin Earth in a circle once.

A student used a hot kettle with boiling water and a cold glass surface to create a water cycle model. Water vapor was coming out the opening of the kettle. After holding the cold surface for 5 minutes above the water vapor (steam) coming out of the kettle, he noticed that water droplets were forming on the cold glass surface.
Where is the condensation process shown in this model of the water cycle?
A:There is no condensation occurring in the model.
B:Condensation occurs when drops of water are collected into the beaker.
C Condensation occurs when steam rises from the hot water in the kettle up into the air.
D Condensation occurs when the water vapor touches the cold glass, cools down, and water droplets are formed.
D Condensation occurs when the water vapor touches the cold glass, cools down, and water droplets are formed.

A student made the following model of the water cycle.
The student adds a bag of ice on top of the plastic wrap.
Describe how this change will affect the water vapor rising from the cup.
A:The plastic bag will break, allowing the ice to melt in the cup.
B: The water temperature in the cup will go down, therefore, there will be no water vapor.
C: There will be no change as the water vapor will continue rising until it escapes from the plastic wrap.
D:The water vapor from the cup will condense when it touches the cold plastic wrap forming water droplets.
D:The water vapor from the cup will condense when it touches the cold plastic wrap forming water droplets.

B:The water droplets condensed out of the air surrounding the cold cup.
C:The water droplets dripped off the ice cubes as she put them into the cup.
D:The water droplets came off her hands after holding the melting ice cubes.

If you examine a piece of hail, it might have invisible layers like an onion.
Which answer best explains why this is true?
A:As hail falls, it picks up layers of dust and dirt from the air.
B:Hail forms layers because it melts as it falls toward the Earth.
C: Air pressure increases while the hail falls, and it causes ice layers to form.
D:Hail builds up ice layers as it travels through updrafts in a storm before it falls.
D:Hail builds up ice layers as it travels through updrafts in a storm before it falls.
