Lecture 1: rock types, mineralogy, physical and chemical weathering. Biogeochemistry: the movement of elements and chemical species between components of the environment. Human impacts the effect of human activities: deforestation, acid precipitation, and accelerated rates of soil erosion. Important questions to answer in this section acid rain. Predicting rates of soil erosion, causes, effects, and alternatives. Human impact on biogeochemistry, effects of forest removal and. Igneous: rocks composed of minerals from molten magma. Intrusive: igneous rock that cools slowly in the crust. Formers a pluton a large batholith of rock that makes up certain mountain ranges. Extrusive: formed as a result of melting of the earth"s crust at the surface. Glossier surface considering they cool much quicker than intrusive.
