2.  There are two types of tides, high and
low, and special tides called spring and
neap tides!

3.  As the moon orbits around the earth and as
they orbit around the sun together travel
around the sun, the combined gravitational
forces cause the world's oceans to rise and
fall.
 Tides also change everyday, as the earth,
moon, and sun orbit, their positions
constantly shift, making the gravity effects
change, this makes tide times a bit different
every day!

4.  Spring tide: When the Moon, Earth, and
Sun fall in a straight line, which we call
syzygy, we can see the greatest distance
between high tide and low tide.
