The Tides
Caused mostly by the moon (but also the sun).
 Moon’s gravity draws ocean water toward it.
 High tide is always the two parts of the world
lined up straight with the moon.
 Low tide occurs in the two spots between.
 It takes ~6 hours to change from high tide to
low tide.
 When the sun and moon line up, tides become
especially strong (spring tide)
 When the sun and moon work against each
other, tides are much weaker. (neap tide)
