Water reshaping worlds
Earth and Water
These pages focus on the ways water behaves very differently at depth, at speed, and over long timescales.
Best Starting Point
Start with What causes tsunamis?
If you want one page that gives the cleanest first pass through earth and water, this is the best place to begin before branching out.
A tsunami lab that lets you change seafloor slip, ocean depth, basin shape, and coastline geometry to compare the deep-ocean wave with the shoreline impact.

If you want the Underwater sound angle first How does sonar work?A sonar lab that lets you change pulse strength, target size, distance, and background noise to compare crisp echoes with weak, cluttered returns.
If you want the Glacier lab angle first How do glaciers form?A glacier lab that lets you change snowfall, cold, summer melting, and compression to compare growing ice fields with retreating glacier margins.
If you want the Wave lab angle first What causes ocean waves?A wave lab that lets you change wind speed, wind duration, fetch, and water depth to compare light chop, long swell, and breaking surf.

How To Explore This Cluster
Use the strongest first page, then branch by sub-question
The point of a topic hub is to keep similar questions connected while still making it easy to choose the right starting page.
