The gravity of the Sun cancels out some of the gravity of the moon so that there isn't much difference in high and low tide.

Electricity produces mechanical energy in a:
an electric motor or anything that contains one: fan, classroom clock, blender, electric pencil sharpener
200
What force causes tides?
gravity
200
Why is high tide directly under the moon?
The moon's gravity pulls more directly on the Earth there, because the moon is directly overhead.
OR
The moon's pull is stronger on the part of Earth that directly faces the moon.
200
Earth rotates on its axis 5 times in ___ days.
5

In figure 4, where are high and low tides?
A and C are high tides; B and D are low tides.

Higher water levels due to tides are useful navigation purposes in some areas. Which location(s) in diagram 2 are most suitable for navigation and why?
A and B because there is more water for ships

Why is there high tide on figure 2 B?
The moon pulls the Earth away from the water behind it.
