1 Weathering and Erosion Weathering the disintegration and decomposition of material at the surface Erosion the transportation of weathered material by water, wind, or ice
2 Weathering Two kinds of weathering Mechanical weathering Chemical weathering
3 Weathering along joints Balanced Rock, Joshua Tree National Monument
4 Weathering along joints Balanced Rock, Joshua Tree National Monument
5 Unloading and exfoliation of igneous rocks
6 Exfoliation joints Tioga Road, Yosemite National Park
7 Exfoliation joints Yosemite National Park: Half Dome
8 Ice wedging expansion of water due to freezing
9 Salt weathering growth of salt crystals due to evaporation of water
10 Prying apart of rocks due to growth of tree roots along joints and fractures
11 Water transport
12 Wind transport
13 Ice transport
14 Weathering Chemical weathering Dissolution of minerals Chemical alteration of minerals by removal/addition of elements
15 Acids: chemical solutions in which hydrogen ions (H + ) are released
16 Formation of carbonic acid CO 2 + H 2 O water and carbon dioxide
17 Formation of carbonic acid CO 2 + H 2 O water and carbon dioxide H 2 CO 3 carbonic acid
18 Formation of carbonic acid CO 2 + H 2 O water and carbon dioxide H 2 CO 3 carbonic acid H + + HCO 3 - hydrogen ion + bicarbonate ion
19 Formation of carbonic acid CO 2 + H 2 O water and carbon dioxide H 2 CO 3 carbonic acid H + + HCO 3 - hydrogen ion + bicarbonate ion 2H + + CO hydrogen ions + carbonate ion
20 Carbonic acid in the ocean
21 Chemical weathering -- dissolution of calcite Granite Limestone
22 Chemical weathering dissolution of limestone or marble
23 Weathering Chemical weathering of silicate minerals Goldich s stability series Stability of silicate minerals increases with the percentage of Si-O bonds: Quartz all Si-O bonds, most stable Feldspars Micas Hornblende Augite Olivine fewest Si-O bonds, least stable
24 Weathering Chemical weathering of silicate minerals Weathering of mafic minerals produces insoluble iron oxides and clay minerals
25 Weathering Chemical weathering of silicate minerals Weathering of mafic minerals produces insoluble iron oxides and clay minerals Weathering of feldspars produces clay minerals and silica in solution
26 Weathering Chemical weathering of silicate minerals Weathering of mafic minerals produces insoluble iron oxides and clay minerals Weathering of feldspars produces clay minerals and silica in solution Quartz remains substantially unaltered
27 Formation of Kaolinite, a clay mineral, from the weathering of Orthoclase 2KAlSi 3 O 8 orthoclase
28 Formation of Kaolinite, a clay mineral, from the weathering of Orthoclase 2KAlSi 3 O 8 + 2H 2 O orthoclase water
29 Formation of Kaolinite, a clay mineral, from the weathering of Orthoclase 2KAlSi 3 O 8 + 2H 2 O + 2H + orthoclase water hydrogen ions
30 Formation of Kaolinite, a clay mineral, from the weathering of Orthoclase 2KAlSi 3 O 8 + 2H 2 O + 2H + orthoclase water hydrogen ions 2K + potassium ions
31 Formation of Kaolinite, a clay mineral, from the weathering of Orthoclase 2KAlSi 3 O 8 + 2H 2 O + 2H + orthoclase water hydrogen ions Al 2 Si 2 O 5 (OH) + 2K + kaolinite potassium ions
32 Formation of Kaolinite, a clay mineral, from the weathering of Orthoclase 2KAlSi 3 O 8 + 2H 2 O + 2H + orthoclase water hydrogen ions Al 2 Si 2 O 5 (OH) + 2K + + 2SiO 2 0 kaolinite potassium ions silica in solution
33 Clay crystals have a charge separation, with positive charges sandwiched between layers of negative charge, making them attractive to water molecules 10 microns = 0.01 mm
34 Spheroidal weathering chemical weathering along surfaces and joint planes
35 Sandcastles collapse when sand dries (pores contain only air) or when sand is saturated (pores contain only water)
36 Sand grains stick together while damp, due to surface tension -- when pores contain water and air, water molecules stick to each other and to sand grains
37 When dry, clay holds about 20% water -- sculptures thus hold their shape through the firing process
38 Rates of weathering Advanced mechanical weathering aids chemical weathering by increasing the surface area Important factors Rock characteristics Mineral composition and solubility Physical features such as joints
39 Rates of weathering Important factors Climate Temperature and moisture are the most crucial factors Chemical weathering is most effective in areas of warm temperatures and abundant moisture
