Hoodoos are rock pinnacles formed by differential weathering and erosion of vertically-jointed horizontal beds of shale interbedded with thin resistant beds of limestone, sandstone, or conglomerate. The best examples and type locality of hoodoos occur in Bryce Canyon, Utah.

biological weathering, accompanied by physical and chemical weathering‘). 7 a level surface of grey limestone with deep gullies crossing it in a rectangular pattern Over thousands of years, the acids in the rain have reacted with the calcite mineral which makes up the limestone – notably in the cracks in the rock, called joints.
Weathering refers to the process by which rocks are broken apart or chemically altered to become sediment. This process can be further subdivided into two categories: physical/mechanical weathering and chemical weathering.
Limestone solution. The limestone solution process is also known as carbonation. Limestone is made of calcium carbonate. When carbon dioxide is dissolved in rainwater, it makes a weak acid called carbonic acid.
Physical weathering is the class of processes that causes the disintegration of rocks without chemical change. The primary process in physical weathering is abrasion (the process by which clasts and other particles are reduced in size).
Over many years, solution of the rock can form spectacular cave systems (see photo). Note: Stalagmites and stalactites form in caves as water drips from the roof, depositing some of its dissolved calcium carbonate, as carbon dioxide is released into the air.

Chemical weathering is caused by rain water reacting with the mineral grains in rocks to form new minerals (clays) and soluble salts. These reactions occur particularly when the water is slightly acidic. Where does it occur? These chemical processes need water, and occur more rapidly at higher temperature, so warm, damp climates are best.
