1. The Tides & Eclipses
MCAS Bootcamp:

2. 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)
