Document Summary
Basic components of earth"s system: bedrock, soil mineral matter, soil organic matter, vegetation and atmosphere. Human impact: acid rain, soil erosion and forest removal. How can we begin to reduce environmental effect. Igneous: rocks composed of minerals formed from molten magma. Sedimentary: rocks composed of minerals weathered from rocks and minerals formed at near surface temperatures and pressures. Metamorphic: formed from secondary pressure and/or temperature processes. Rocks are being formed by being physically and chemically weathered and transported to form new rock cycles transported to form new rock cycles. Cycle that goes on all started with the mantle. Rocks can be complex in its origin and we thus find many rock types - intrusive (size of minerals is bigger) or extrusive (size of minerals is smaller) Individual minerals include the following minerals: oxygen, silicon, aluminum, iron, calcium, sodium, potassium, magnesium, nitrogen, carbon, phosphourous, sulfur) Important in plant nutrients: calcium, potassium, magnesium, nitrogen, potassium, sulfur.
