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.
The diagram shows a landscape.
Where in the diagram would the air pressure be the greatest?
A
at the beach
B
on top of the mountain
C
above Earth's atmosphere
D
at the bottom of the clouds
A
at the beach
Our solar system lies within the Milky Way Galaxy.
Which of the following best describes what makes up a galaxy?
.A:A star and planets
B:Gas, dust, and many solar systems
C:One planet and a moon orbiting a star
D:Hundreds of stars that make a shape in the sky
B:Gas, dust, and many solar systems
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.
A meteorologist studies the local weather and climate for the region that they live in. A meteorologist for a local radio station in Tampa is giving the weather information for the first day back to school. He announces that the humidity will be high and the air pressure is low. Which additional data would also describe the current local weather?
A
the current wind speed and direction
B
the current times for sunrise and sunset
C
the average rainfall for the current month
D
the average temperature for the current month
A
the current wind speed and direction
What two properties of stars can affect how bright they appear?
3.A:color and age
B:mass and revolution
C:distance from Earth and size
D:rotation speed and composition
C:distance from Earth and size
Theresa sets her glass of lemonade down on the table on a hot, humid summer day. Ten minutes later, she notices that the glass has drops of water on the outside and a pool of water at the base of the cup.
What causes the formation of the water droplets on the outside of the cup?
A:The water droplets evaporated out of the air above the cold liquid.
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.
B:The water droplets condensed out of the air surrounding the cold cup.
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.
