Whose name is associated with the theory of isostasy?
Quick Answer
George B. Airy and John Henry Pratt are both tied to early isostasy models. Their ideas explained how mountains can float in balance on denser Earth material below.
The Full Story
In the 19th century, George Biddell Airy and John Henry Pratt proposed different models to explain why Earth's crust can remain in gravitational balance despite huge mountain ranges. Airy's version imagined thick crustal roots beneath mountains, while Pratt's model used variations in crustal density. Together, their work became known as isostasy. The concept is fundamental for understanding mountain building, crustal buoyancy, and how the lithosphere responds to loading.
