Approximately how long does it take the Moon to orbit the Earth?
One month (around 28 days)
100
At what angle is Earth's axis tilted?
23.5 degrees
100
Tides are mostly caused by
the gravitational pull of the Moon on Earth's waters
100
Why don't eclipses happen often?
The Sun, Earth, and Moon have to be perfectly aligned for an eclipse, which rarely happens.
100
The amount of time it takes for the Earth to rotate once on its axis.
24 hours
200
Which moon phases are represented in positions 1 and 4?
New Moon (1)
Waxing Gibbous (4)

Which type of tide is shown in the image?
Spring tide (extra deep tides)
200
What type of eclipse is shown in the image?
Solar eclipse
200
The amount of time it takes for the Earth to orbit the Sun.
365 1/4 days (1 year)
300
Which moon phases are represented in positions 5 and 8?
Full Moon (5)
Waning Crescent (8)
300
When the Northern Hemisphere is tilted toward the Sun, what type of sunlight does the Southern Hemisphere receive?
Indirect sunlight
300
Which type of tide is shown in the image?
Neap tide (less deep tides)
300
What type of eclipse is shown in the image?
Lunar eclipse
300
Of the 8 planets, where does Earth fall on the ranking of size?
5th largest
400
What is the approximate scaling of the Earth and Moon?
a) the Moon is half the size of Earth
b) the Moon is a quarter the size of Earth
c) the Moon is three quarters the size of Earth
b) the Moon is a quarter the size of Earth

If Earth's axis was not tilted, there would be no seasons. Explain why.
If the axis was not tilted every part of the Earth would constantly face the Sun at the same angle, never experiencing cooling or heating seasons.
400
Explain what causes spring tides (include the correct moon phases in your explanation).
The moon and Sun work together to pull on the Earth, causing extra deep tides. Occurs during full and new moons.
400
Explain the differences between a shadow's umbra and penumbra.
Umbra - smaller, darker, in the center
Penumbra - larger, brighter, on the edges

If the Moon is always half lit by the Sun, why do we see different amounts of light on the Moon?
As the moon orbits the Earth, its position changes and the angle of light we can see also changes.
500
What would the climate of an area with a latitude of 62 degrees S be like? What would the climate of an area with a latitude of 26 degrees S be like? Why are they different?
62 degrees S = colder climate
26 degrees S = warmer climate
62 is closer to the poles, 26 is closer to the equator
500
Explain what causes neap tides (include the correct moon phases in your explanation).
The moon and Sun are working against each other at a right angle, causing lower than usual high tides. Occurs during the quarter moons.
500
Where would you have to be to see a partial solar eclipse like in the image?
In the penumbra of the Moon's shadow during a solar eclipse.
500
Why do we have leap years?
Since the Earth's orbit is 365 1/4 days, we add an extra day to the calendar every 4 years to make up for the extra 1/4 day.
