Minerals and Rocks

A mineral is a naturally occurring substance with distinctive chemical and physical properties, composition and atomic structure.

Rocks are generally made up of two of more minerals, mixed up through geological processes. For example granite is an igneous rock mostly made from different proportions of the minerals quartz, feldspar and mica as interlocked crystals; a sandstone is a sedimentary rock that can also contain quartz, feldspar and mica, but as grains compacted and cemented into each other.

Wallpaper Description:

Tsingy de Bemaraha _National Park, Madagascar

The Tsingys are karstic plateaus in which groundwater has undercut the elevated uplands, and has gouged caverns and fissures into the limestone. Because of local conditions, the erosion is patterned vertically as well as horizontally. In several regions on western Madagascar, centring on this National Park and adjacent Nature Reserve, the superposition of vertical and horizontal erosion patterns has created dramatic "forests" of limestone needles._Wikipedia
