100
What are the four main phases of the moon?
New Moon, First Quarter, Full Moon, Last Quarter
100
What causes the moon to have phases?
The reflection of sunlight off the moon's surface as it orbits the Earth.
100
What is the term for the moon's orbit around the Earth?
Revolution
100
What is a solar eclipse?
When the moon passes between the Earth and the Sun, blocking the Sun's light.
100
What is the dependent variable?
The factor that is being measured or observed
200
During which phase is the moon completely illuminated?
Full Moon
200
What phase is this moon in?
1st Quarter
200
What force keeps the moon in orbit around the Earth?
Gravity
200
What is a lunar eclipse?
When the Earth passes between the Sun and the moon, casting a shadow on the moon
200
What happens to the overall the average temperature of the planets as their distance increases from the sun?
The average temperature of the planets decrease
300
What phase comes after a New Moon?
Waxing Crescent
300
How does the angle of sunlight affect the moon's appearance?
It changes how much of the moon's surface is illuminated that we can see from Earth.
300
Why do we only see one side of the moon from Earth?
Because the moon's rotation period is the same as its revolution period.
300
What causes ocean tides?
The gravitational pull of the moon and the Sun on Earth.
300
Is the Nothern Hemisphere experiencing Summer or Winter?
Winter
400
What is the term for the moon phase when it appears to be getting smaller and the term when it appears to get larger?
Smaller: Waning
Larger: Waxing
400
Explain why a New Moon is completely dark.
Because the illuminated side is facing away from Earth.
400
How long will it take the moon to get from Position B to position D?
About 2 weeks
400
Explain the difference between a total and partial eclipse.
A total eclipse completely covers the Sun or moon, while a partial eclipse only partially covers them.
400
Explain why summer days in North America are likely to be hotter than winter days
Earth's northern hemisphere is tilted toward the Sun and experiences more direct sunlight than winter when it is tilted away
500
How long does it take for the moon to complete one full cycle of phases?
About a month
500
What moon phases FOLLOWS this one?
Last (3rd) Quarter
500
Describe the relationship between the Earth's rotation and the moon's revolution.
The Earth's rotation affects how we see the moon moving across the sky while it orbits the Earth.
500
How does the position of the moon affect the timing of tides?
The moon's position changes the gravitational pull on the oceans, causing tides to rise and fall at different times.
500
Describe the Big Bang Theory
12-15 billion years ago a subatomic particle exploded creating the universe.
