What is the definition of weathering? Process of disintegrating solid rock and producing loose debris
What are the two types of weathering? CHEMICAL WEATHERING & PHYSICAL WEATHERING
Match each term with its proper definition Chemical Weathering Dissolution Hydrolysis Oxidation Physical Weathering
Match each term with its proper definition Chemical Weathering: C. decomposition of rocks and minerals as chemical reactions alter them into new minerals stable at Earth’s surface. Dissolution: E. process where a mineral passes completely into solution. Hydrolysis: A. chemical reaction where water and another substance both decompose into ions. Oxidation: B. chemical combination of oxygen (in atmosph. or water) w/ 1 mineral to form a different mineral w/ higher oxidation state. Physical Weathering: D. disintegration of rocks by physically breaking them apart.

Fill in the blank!! Amount of rainfall and temps influence weathering. Humid/tropical climates produce chemical weathering with thick soil. Deserts produce physical weathering with thin soil. Polar climates produce physical weathering with thin soil. Feldspars weather to clay Micas weather to clay Quartz weathers to quartz Basalts weather to clays, iron oxides, Al oxides.

True or False?? An increase in rainfall causes an increase in reactions. A decrease in temperature causes an increase in reactions. The A horizon of soil is dark grey to black and rich in organic matter. The B horizon of soil is composed of the parent rock in various stages of weathering. The C horizon of soil is composed of leached material from above.
