Explain the difference between rotation and revolution. Then use these terms to explain how Earth, the moon, and the Sun move relative to one another.
Rotation is the spin of an object on its axis, while revolution is the movement of one object around another in an orbital path. Earth rotates on its axis about once every 24 hours and revolves around the Sun once every year. Similarly, the moon rotates on its own axis and revolves around the Earth approximately every 27.3 days.

Explain what causes spring and neap tides, and identify the phases of the moon when these tides occur. Be sure to mention what happens to Earth’s crust, ocean water, and the positions of the Sun, Earth, and the moon.
Spring tides occur during the new and full moon phases when the Sun, Earth, and Moon are aligned in a straight line. In this position, the combined gravitational pull of the Sun and the Moon acts on Earth’s crust and ocean water, leading to higher than normal high tides and lower than normal low tides. Neap tides occur during the first and third quarter moon phases when the Sun and Moon are at right angles to each other relative to Earth. Because the gravitational pulls of the Sun and Moon offset each other, the tidal range is minimized, resulting in lower high tides and higher low tides.
Sample Response: Spring tides occur when the moon is full or new. Earth, the moon, and the Sun are in a line. The moon’s gravity and the Sun’s gravity pull Earth’s crust and ocean water. This causes tides to be higher than normal. At neap tide, the moon and the Sun are at right angles to each other. This happens during the first and third quarters of the lunar cycle. At neap tide, the Sun’s gravity and the moon’s gravity are balanced. High tides are lower; low tides are higher. What did you incl
