4. 3. In recent years, water has been found on the surface of the moon
3. In recent years, water has been found on the surface of the moon. This water was not originally detected because –
It is located inside dormant volcanoes in large lakes
It is frozen in craters where the moon’s surface receives little sunlight.
It bubbles up on limited occasions from springs in the moon’s crust.
It only exists as water vapor in the moon’s atmosphere.

5. 4. On which side of a house in Texas should a window be placed so that the people inside the house can see the sunrise each morning?
North
South
East
West

6. 5. The Earth has four seasons each year
5. The Earth has four seasons each year. Why don’t the Southern Hemisphere and Northern Hemisphere experience the same seasons at the same time?
because the Earth is tilted on its axis which prevents direct sunlight from hitting both the Northern and Southern Hemispheres at the same time.
because the rotation of the Earth on it axis keeps one hemisphere turned away from the sun while the other hemisphere is facing it.
because the Southern Hemisphere is always cold due to the polar icecaps.
because as the Earth revolves around the sun the Northern Hemisphere is closer to the sun when Earth’s elliptical orbit passes on the left side of the sun and the Southern Hemisphere is closer to the sun when the elliptical orbit passes on the right side of the sun.

7. 6. Why does the Sun appear to move across the sky?
The Sun revolves around the Earth.
Earth revolves around the Sun.
The Sun rotates on its axis.
Earth rotates on its axis.

8. 7. A neap tide occurs when the Sun’s gravitational pull –
Works with the moon’s gravitational pull creating a higher than normal high tide.
Works with the moon’s gravitational pull causing a massive rogue wave.
Works against the moon’s gravitational pull to create a lower than normal high tide.
Works against the moon’s gravitational pull to create flooding in low tide areas.

9. 8. Jake had a friend measure the length of his shadow four times on the same day, at 8:00am, 1:00pm, 6:00pm, and 8:00pm. The friend recorded the following measurements:
8.0m
4.2m
3.1m
0.3m
Jake’s friend forgot to record the time of day beside each measurement. Which measurement was made at 1:00pm?

10. 9. If you were standing near “X” on Earth, it would be –
Spring
Daytime
Sunday
Nighttime

11. 10. How long does it take Earth to rotate approximately once on its axis?
1 hour
1 day
1 month
1 year

12. 11. What do the Earth and Moon have in common?
They both have the same gasses in their atmosphere.
Gravity is the force that keeps them both in their orbits
The surface gravity of the Earth and Moon is the same.
Earth and Moon both have one natural satellite.

13. 12. Why does erosion happen on Earth but not on the Moon?
The Moon does not receive enough sunlight to erode.
The Moon does not experience wind or rain since it does not have an atmosphere.
The rock on the Moon is too hard to erode
Erosion occurs only where there is plant and animal life.

14. 13. One complete revolution of our planet around the Sun is one –
Day
Season
Year
Month

15. 14. Ann was on a camping trip and noticed that the stars seemed to change position during the night. What explains the apparent movement of the stars?
Earth’s revolution makes it appear the stars are moving.
The stars are moving away from the Earth.
Earth’s rotation makes it appear the stars are moving.
The Milky Way galaxy is moving.

16. .
15.
At which of the points labeled on the globe would it be midnight (the curved arrows show the direction of
the
Earth’s rotation)? A. A B. B C. C D. D

17. 16. Dark spots on the sun where gasses are cooling and condensing are known as _________________________?
Craters
Sunspots
Solar Flares
Prominences

18. 17. Which of the following best describes rotation?
The length of time it takes for Earth to turn on its axis
The length of time it takes the Moon to go around the Earth
The length of time it takes Halley’s Comet to go around the Sun
The length of time it takes Venus to go around the Sun

19. 18. An eruption from a sunspot on the surface of the Sun is know as a –
Solar Flame
Solar Flag
Solar Fleece
Solar Flare

20. 19. We can only see one side of the Moon’s surface, but the entire surface of the Moon is hit by sun rays at some point. Why can we only see one side of the Moon?
The Moon revolves around the earth at the same rate that the Earth spins on its axis so one side of the planet (North and South America) sees one half of the Moon while the other side of the planet (China and India) see the other half of the Moon.
The Moon does not rotate on an axis.
The Moon rotates on its axis in the exact same amount of time that it revolves around the Earth (27.3 days) and the synchronous orbit and rotation prevent us from seeing one side of the Moon.
The Moon is shy and only shows its other side when everyone is asleep.

21. Which of the following is not one of the things that the sun provides for the Earth?
The sun gives heat energy to the Earth.
The sun creates life on Earth.
The sun’s gravity holds the Earth in its orbit
The sun gives light energy to the Earth

23. 22. How much gravity does the Moon have compared to the Earth?

24. 23. We have two high tides (and low tides) every ___________________ hours.

25. Bonus Questions:
24. Who was the first United States astronaut to make a successful trip into outer space?

26. 25. What is the name of the universe model that Greek philosophers such as Aristotle and Ptolemy originally developed? This model places the Earth in the center of the universe with all the planets (and the Moon) revolving around it instead of the sun.

27. 26. Can you name the outermost layer of the sun’s atmosphere?
