Here are some features that are not the result of glaciers carving out rocks:

* Volcanoes: Volcanoes are formed by the eruption of magma from the Earth's interior.

* Sand dunes: Sand dunes are formed by the wind depositing and shaping sand.

* Canyons: Canyons are typically formed by rivers eroding through rock over long periods of time.
