External Forces One And Two
External Forces One and Two
Weathering- is the process that changes solid rocks into sediments. There are four types of weathering water, wind, glaciers, and gravity
Water is responsible for most weathering
Wind moves sand-sized particles of rock through the air
Glaciers move all sizes of sediment
Gravity moves broken pieces of rock downslope
Physical Weathering- involves the breaking down of rocks into situ without any change in the composition
Freeze Thaw- when water seeps into the cracks and freezes increasing in space. It then cracks the rock and moves downwards and repeats this process
Exfoliation- while rocks expand during the day and contract at night, eventually lines of weakness will appear causing the rock to start peeling in layers
Plant Growth- When the roots of plants wedge themselves into the cracks of rocks. As they grow they forces the crack in the rock to get bigger
Chemical Weathering- changes the chemical composition of rocks. It works through the chemical reactions that cause change in the minerals
Oxidation- is a chemical reaction that takes place when oxygen reacts with another element
Chemical Weathering by CO2- combined with the water as rain falls in makes an acid called Carbonic Acid which then creates acid rain (which dissolves rocks)
Differential Weathering- the composition of the ricks and minerals it contains as well as the climate or a region
Climate- the weather in a certain area (warmer climates produce the highest rate of weathering)
Dissolved Load- is composed of ions in solution that re usually carries in the water all the way to the ocean
Suspended Load- sediments carried as solids as the stream flows are a suspended load. The size of the particles can be carried as determined by the streams force
Bed Load- particles that are too large to be carried
Gorge- when an overhang forms eventually the unsupported mass will collapse and the entire waterfall will move backwards repeating this process
Canyon- results when a
