Question What happens in space that creates ONE DAY on Earth?

Answer 1 – 10 1 Rotation of Earth

Question What happens in space to create about ONE MONTH on Earth?

Answer 1 – 20 1 Revolution of the moon around the Earth

Question What happens in space that creates ONE YEAR on Earth?

Answer 1 – 30 1 revolution of Earth around the sun

Question What force creates predictable planetary motion?

Answer 1 – 40 Gravity

Question What happens to the amount of gravity the further objects are from one another?

Answer 1 – 50 Gravity decreases

Question Draw a gibbous moon.

Answer 2 – 10

Question 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 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 What percentage of the moon is always reflecting sun’s light?

Answer 2 – 40 50%

Question 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 4 – 50 Moon’s orbit is tilted and to have an eclipse, the sun, moon, and Earth must be lined up.

Question What causes tides?

Answer 5 – 10 Sun and moon’s gravitational pull on Earth’s oceans

Question About how many tides occur in a day?

Answer 5 – 20 4 tides per day (2 high tides, 2 low tides)

Question How long is a tidal day?

Answer 5 – hours and 50 minutes

Question Draw a picture of a neap tide and a spring tide.

Answer 5 – 40

Question 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.
