Moon Tides

We just learned about Gravity on the Moon.

The moon orbits the earth about every 27 days, and the earth spins around once every day.

Because the moon is so big, as it is spinning around the earth it affects the oceans and lakes.
This is called Tide.

When a part of the ocean is facing where the moon is, the water rises up.
Then when the earth spins and the moon orbits, the water goes down.
When the ocean is facing totally opposite of where the moon is, the water rises up again.
And when the earth spins again the water goes down.

If you live on an ocean or lake, you can see the water rise up to the beach for a few hours, then go back out for a few hours.
