How tides of the solid Earth differ from ocean tides
The solid Earth flexes under the same tidal pull, but the oceans travel much farther.

From the opening
Solid-Earth tides are the elastic flexing of the crust and mantle under the gravity of the Moon and the Sun. The same forces raise the ocean tides, but water can flow, so the sea's rise and fall is much larger and is shaped by coasts and basins. The opening covers the tidal force both share, why water can travel farther, and what a load tide adds.
The rest of the brief — the later sections and the reading notes — opens after Stripe confirms payment.
