Which of the following is true about planetary rotation and revolution?
Earth’s rotation is what causes day and night, while Earth’s revolution is what causes seasons.
All planets have the same rotation periods.
All planets have the same revolution periods.
Earth’s revolution is what causes day and night, while Earth’s rotation is what causes seasons.
In order to stay in orbit, two factors play a role in keeping planets in motion. Which of the following is true?
Planets need a larger amount of gravity than inertia to keep them in motion.
Neptune has the largest amount of gravity and magnetic force acting on it in order to keep it in motion.
Gravity and inertia help planets move in a spherical path around the sun.
The amount of gravity acting on Venus is equal to the amount of inertia also acting on it.
What would happen to the moon if Earth's gravity was removed?
nothing would happen
it would fly out of orbit in a straight line and then start orbiting another planet
it would fly off in space and then just stop
it would fly out of orbit in a straight line and continue forever unless something gets in its way
Michael and Danielle are talking to each other about which planet they would like to move to. Michael says he would want to move to Neptune because summer would last longer than on Earth. Pick which of the following best supports his answer.
Planets furthest from the sun take longer to orbit the sun, meaning they have a longer revolution period.
Planets further from the sun take longer to orbit the sun, meaning they have a longer rotation period.
Planets closest to the sun take longer to orbit the sun, meaning they have a longer revolution period.
Planets closest to the sun take longer to orbit the sun, meaning they have a longer rotation period.
Which of these would be shorter if Earth ROTATED faster?
days
months
years
weeks
Which of these would be shorter if Earth REVOLVED faster?
days
months
years
weeks
Which of the following about the motion of the moon compared to the motion of the planets is false?
Both moons and planets rotate and revolve.
Earth takes a shorter amount of time to revolve around the sun than the moon takes to revolve around the Earth.
The planets revolve around the sun, while the moons revolve around the planets.
It takes a longer amount of time to complete a revolution than a rotation for both moons and planets.
Alyssa thinks we can only ever see one side of the moon from Earth. Pick one the following to either support or reject her statement.
I reject Alyssa’s statement because the moon rotates on its axis more than it revolves around Earth.
I reject Alyssa’s statement because the moon experiences phases that lights up a different part of the moon every night.
I support Alyssa’s statement because the moon has a synchronous rotation, which causes it to rotate at the same pace it revolves.
I support Alyssa’s statement because the moon reflects the same amount of light from the sun everyday.
Based off the position of the sun, the moon, and the Earth, what is the moon phase at number 5?
3rd quarter
Waxing gibbous
Waning gibbous
Waning crescent

July 27
Using the same moon phase calendar, on which night was the moon furthest from the sun?
July 8
July 16
July 1
July 23
Based off this image of the moon, which of the following is the most likely position of the moon, the sun, and the Earth?
The day of the year with the most daylight hours is the
spring equinox
fall equinox
summer solstice
winter solstice
In the northern hemisphere, the winter solstice happens in which month?
March
June
September
December
On the day that the northern hemisphere has it's longest day, the southern hemisphere will have it's shortest day.
True
False
120°W, 45°N
Based off the following information, which of the following best fits your location?
-It is June
-There is little difference between low and high tide
-The days consist of 6 hours of sunlight
You are located in the southern hemisphere and it is a full moon.
You are located in the northern hemisphere and it is a full moon.
You are located in the southern hemisphere and it is a quarter moon.
You are located in the northern hemisphere and it is a quarter moon.
How would you expect the charges to line up within this object?
How would you expect the charges to look like within this object?
Which of the following claims best explains this graph?
When the distance between the magnet and the paper clip increased, the magnetic force increased.
When the distance between the magnet and the paper clip increased, the electric force increased.
When the distance between the magnet and the paper clip increased, the magnetic force decreased.
When the distance between the magnet and the paper clip increased, the electric force decreased.
Rebecca thinks that life would change for us if Earth did not have a magnetic field. Which of the following best supports her thought?
Many animals and plants would go extinct
There would be no ocean tides
The temperature would remain constant
The Earth would fall out of orbit
Which of the following most closely resembles an electromagnet?
Two bar magnets are held close together. They are released and allowed to move freely. The bar magnets quickly come together. Which best explains why this happens?
The poles facing one another are both south poles
The poles facing one another are both north poles
The poles facing one another are opposite poles
One magnet was bigger than the other
Frederick sets paper clips out on a table. He then takes a magnet, places it directly beneath the paper clips under the table, and moves the magnet. He finds that the paper clips move with the magnet. Why does this happen?
Magnetic force is a repellant force
Magnetic forces act on wood, like in the table
The paper clips are feeling the gravitational force of the magnet
Magnetic forces act at a distance, even between objects
In an electromagnet, coils of wire are wrapped around a magnetic object to generate a magnetic field. What the is relationship between number of coils and the strength of the magnetic field?
The more coils an electromagntic has, the stronger the magnetic field
The more coils an electromagntic has, the weaker the magnetic field
The larger the metal object, the stronger the magnetic field is
There is no relationship between number of coils and the strength of a magnetic field
To decrease the strength of a magnetic field around an electromagnet, we must
increase the number of coils
increase the size of the iron core
decrease the size of the iron core
decrease the number of coils
You have two pairs of charged objects interacting with each other. The first pair (A and B) are 10 cm apart. A has a +1 charge and B has a -1 charge.
Pair C and D are 17cm apart. C has a +1 charge, and D has a -1 charge.
Which of these statements is true?
There are no electric forces because the charges in each pair of objects cancel.
The electric force between A and B is smaller than the electric force between C and D.
The electric force between A and B is greater than the force between C and D.
The electric force between A and B is identical in magnitude to the electric force between C and D.
What happens when a rubber rod is rubbed with a piece of fur, giving the rod a negative charge?
Negative charges are moved from the rod to the fur.
Negative charges are moved from the fur to the rod.
Negative charges are added to the rod and the fur remains neutral.
Positive charges are removed from the rod, and the fur remains neutral.
Can neutral objects become charged?
Yes, by wishing it to be so.
No, never.
Yes, by being near or in contact with a charged object.
No, not under any circumstance.
