9What causes tides?
- Tides are caused by gravity between the Earth,
moon, and sun
10What causes tides?
- The moons gravity pulls on Earths surface
closest to the moon causing water to create a
bulge - Water is stolen from the sides to create the
bulge - The side of Earth furthest from the moon has the
least effect of moons gravity and has a bulge
that is the left behind water
11Different kinds of tides
- The suns gravity can add to the moons pull or
even it out depending on the positions of the
sun, moon and Earth
