Question 1 - 10
What happens in space that creates ONE
DAY on Earth?
Answer 1 – 10
1 Rotation of Earth
Question 1 - 20
What happens in space to create about ONE
MONTH on Earth?
Answer 1 – 20
1 Revolution of the moon around the Earth
Question 1 - 30
What happens in space that creates ONE YEAR
on Earth?
Answer 1 – 30
1 revolution of Earth around the sun
Question 1 - 40
What force creates predictable planetary
motion?
Answer 1 – 40
Gravity
Question 1 - 50
What happens to the amount of gravity the
further objects are from one another?
Answer 1 – 50
Gravity decreases
Question 2 - 10
Draw a gibbous moon.
Answer 2 – 10
Question 2 - 20
Why do we see moon phases from Earth?
Answer 2 – 20
The position of the Earth, sun, and moon. We
see different parts of reflected light depending
on where the moon is in its orbit.
Question 2 - 30
What is the difference between waxing and
waning moons?
Answer 2 – 30
Waxing moons have an increasing amount of
reflected light that we can see.
Waning moons have a decreasing amount of
reflected light that we can see.
Question 2 - 40
What percentage of the moon is always
reflecting sun’s light?
Answer 2 – 40
50%
Question 2 - 50
Is there such a thing as a dark side of the moon?
(meaning one side is ALWAYS dark, receiving
no light)
Explain why or why not.
Answer 2 – 50
No. The moon always has day and night just like
Earth. The moon both rotates and revolves,
but at the same rate. For every revolution the
moon makes around the Earth, the moon also
rotates one time.
Question 3 - 10
What causes seasons?
Answer 3 – 10
The tilt of Earth’s axis, which causes direct and
indirect light on Earth.
Question 3 - 20
Why is direct light warmer than indirect light?
Answer 3 – 20
Direct light is more concentrated (same amount
of energy in a smaller area)
Question 3 - 30
If it is summer in the northern hemisphere,
what season is it in the southern hemisphere?
Answer 3 – 30
Winter
Question 3 - 40
If the north and south poles get 6 months of
light no stop, then why is it still cold during
that time of year?
Answer 3 – 40
Because the north and south poles always
receive indirect light.
Question 3 - 50
Identify the season in the northern hemisphere
in figure III
Answer 3 – 50
Summer
Question 4 - 10
Draw a labeled diagram of a solar eclipse
Answer 4 – 10
Question 4 - 20
Draw a labeled diagram of a lunar eclipse
Answer 4 – 20
Question 4 - 30
What is the most common type of eclipse?
Answer 4 – 30
Lunar Eclipse
Question 4 - 40
What phase of the moon do solar eclipses
occur?
Answer 4 – 40
New moon
Question 4 - 50
Why do we not have eclipses every month?
Answer 4 – 50
Moon’s orbit is tilted and to have an eclipse, the
sun, moon, and Earth must be lined up.
Question 5 - 10
What causes tides?
Answer 5 – 10
Sun and moon’s gravitational pull on Earth’s
oceans
Question 5 - 20
About how many tides occur in a day?
Answer 5 – 20
4 tides per day
(2 high tides, 2 low tides)
Question 5 - 30
How long is a tidal day?
Answer 5 – 30
24 hours and 50 minutes
Question 5 - 40
Draw a picture of a neap tide and a spring tide.
Answer 5 – 40
Question 5 - 50
Below is a graph of tides over the period of a
few months.
Explain why some high tides are higher than
others at certain points.
Answer 5 – 50
The higher high tides occur during spring tides
because the moon and sun are working
together.
The lower high tides occur during neap tides
because the moon and the sun are NOT
working together.
