If the Sun is bigger than the Moon, why does the Moon have a greater effect on the tides?
The Earth blocks the Sun's gravitational pull
The Moon is much closer to Earth than the Sun
Although the Moon is smaller than the Sun, it has more mass
The Sun's gravity doesn't affect water
High tides occur:
At either the North Pole or the South Pole, depending on where the Moon is
On the side of the Earth facing away from the Moon only
On the side of the Earth facing the Moon only
On the side of the Earth facing the Moon and also on the opposite side

What might happen on a beach as the tide goes back out into the water?
Sandcastles built by kids might get washed away by the ocean

What might happen if the moon were only half as large as it is now?
There would be no tides at all
Most areas would receive fewer high tides each day
The ocean level would rise and fall less dramatically
Ocean waves would not be very large, they would be tiny
