Tides & Spinning Worlds

Gravity doesn't just hold planets in orbit: it stretches them. Discover why the oceans bulge on both sides of the Earth, how the Sun and Moon team up for spring tides, why the Moon is slowly drifting away, and what really happens on a spinning planet, from hurricanes to Foucault's pendulum. Finally, see why some bays have giant tides and how tide tables are predicted.
