Other information
 Twice
a day, the water rises and goes
down again. The tides are caused by the
pull from the gravity of the Moon and the
Sun. Gravitation keeps the planets in orbit
about the Sun.
High tide

When the Sun and the Moon are lined up
with the Earth, they have a great
gravitational pull on the Earth. When
this happens, it causes the water to be
pulled away from the Earth.
Low tide
When your area is not lined up with the Moon, you will have low tides. The low spring tides are
usually the best for exploring.
