Gypsum performs a substantial role in shaping various geographical landforms, notably in desert environments and karst topography. In this article’s an exploration of how gypsum influences these landscapes:
Halite has a few fantastic cleavages that form at right angles to variety cubes. Gypsum crystals have only one particular excellent cleavage way. The opposite two cleavage directions are not as pronounced, so broken gypsum crystals usually form rhomb-shaped fragments, in lieu of cubes.
