Why Earth Has Two Levels | Hypsometric Curve
To learn more about this topic, start your googling with these keywords: Hypsometric Curve: Basically, a chart that shows the proportions of surface area at every elevation on a planet.

Geologists talk about things like "isostatic rebound," which is what happens after an ice age, when the ice melts off a continent and the continent lifts up, like a floating raft in a pool after someone gets off (though continents rise more slowly).
