Document Summary

Weathering and erosion rock and deposits them elsewhere. Two types of weathering surface cause rocks and minerals to break down. Erosion is the process by which moving water, wind, ice or gravity moves pieces of. Weathering is the process by which atmospheric agents at or near the earth"s. Chemical weathering takes place when minerals in a rock are chemically rain), you"re dissolving the tombstone and they get etched and crap. Physical weathering takes place when rock becomes fragmented by physical. Limestone tombstone (calcium carbonate) and adding acid (by acid. Breaking it down and making it smaller (nature smashing something processes with no chemical alternation altered of dissolved to smaller) Many rocks have pre-existing fractures called joints (cracks) Large, flat, curved sheets of rock fracture and are detached from an outcrop. When ice wedges between a crack in form of water and freezes and expands and breaks things apart. Corners weather fastest; 3 sides of attack.
