The word for when something spins (like the Earth spinning on it's axis)
What is rotate or rotation?

The predictable raising and lowering of ocean levels due to the gravitational forces of the sun and moon.

How is Earth's axis positioned?
What is at an angle?

What is the moon?
200
What happens with the position of Earth's axis as we revolve around the sun?
Nothing, it always points in the same directions.
300
The position the full moon would be in
What is position 5?
300
Describe the movement of the Earth, sun, and moon relative to each other in space.
The Earth revolves around the sun while the moon revolves around the Earth.
300
What type of eclipse can only happen during a new moon?
What is a solar eclipse.
300
This is the tide that happens when the sun, moon, and Earth are all in line, creating extreme tides.
What is a spring tide?

How does the Earth's tilt cause us to have Seasons?
We receive different concentrations of light depending on whether we are tilted toward the sun, away from the sun, or neither toward or away from the sun.
400
The position the new moon would be in
What is position 1?
400
Why do we have eclipses?
When one celestial body (like the moon or Earth) are in a line, one of the bodies casts a shadow on the other body.
400
What astronomical event is happening in the diagram below? How do you know?
What is a lunar eclipse because the Earth is between the moon and the sun, causes the Earth to cast a shadow on the sun. The diagram shows the moon behind the Earth and the shadow hitting the moon, so we know it is not just a full moon.
400
This is the tide that happens when the sun and moon are at right angles to each other, causing tides with smaller differences between high and low tide.

Using the information on this graph, explain why the high and low tides are happening later and later each day.
The moon is rises and setting later each day and the tides are mainly caused by the moon's gravitational pull.
500
When the northern hemisphere is experiencing spring, what season is the southern hemisphere experiencing?
