Buttes, mesas, and inselbergs represent A.pinnacles of rock and rock masses that were uplifted by compressional forces. B.erosional remnants of a once extensive and continuous rock layer. C.erosional remnants of vertically tilted strata. D.the erosional remnants of volcanoes (i.e., volcanic necks).

Mesas are broad flat topped mountains with at least one steep side. Buttes are smaller flat topped mountains or hills with steep slopes on all sides. Spires (also towers, needles, and balanced rock) are slender isolated columns of rock, that form as the erosional remnant of a butte.

The classification of Anthony Young (1969) distinguishes six types of inselbergs; buttes, conical hills, convex-concave hills, rock crest over regolith-covered slope, rock dome (sugarloaf) and kopje or tor.

Mesas and buttes. Formed in flat-lying sedimentary layers. They have flat tops, steep eroded sides and scree slopes. Wider than they are tall. Mesas can occur in groups, but are more often stand isolated. Mesas are remnant parts of a larger sedimentary table-top plateau
