潮汐为何每天涨落两次，源于月球引力？

The Moon’s gravity pulls Earth’s oceans more strongly on the side nearest it.
A second tidal bulge forms on the opposite side due to inertia and centrifugal force.
As Earth rotates, most coastal locations pass through both bulges every 24 hours and 50 minutes.
This creates two high tides and two low tides approximately every lunar day.
Sunlight also influences tides, but the Moon contributes about 70% of tidal force.
Spring tides occur during full and new moons when Sun and Moon align.
Neap tides happen during quarter moons when gravitational pulls partially cancel each other.
Tidal ranges vary greatly depending on coastline shape and ocean basin resonance.
Some places like the Bay of Fundy experience tides over 15 meters high.
Tide-powered turbines convert this predictable motion into renewable electricity today.
