3 major rock classifications - igneous, sedimentary, metamorphic anthropogenic cause - human caused climate change benefits for drugs and medicine - more than half of all modern medicines contain some natural product from a wild species Benefits of biodiversity in food - wild plants could provide new sources of food or more genetic diversity for existing crops biodiversity hotspots - tropical rainforests and coral reefs Biopiracy - Resources often extracted without compensation Bushmeat trade - The trade and sale of wild animals for food, cause of extinction in animals chemical weathering - selective removal or alteration of specific components that leads to weakening and disintegration of rock. Oxidation, Acid rain, & lichens climax community - develops last and remains the longest Core - interior composed of dense, intensely hot metal, mostly iron. Generates magnetic field enveloping the earth. Crust - cool, lightweight, brittle outermost layer. Floats on top of mantledisturbance - any force that disrupts established patterns of species diversity and abundance, community structure, or community properties. Ex: storms, fire, logging DNA sequencing and other molecular techniques - give insight into taxonomic and evolutionary relationships Dredging - Mining technique using draglines & chain buckets to scrap underwater mineral deposits Earthquakes - caused by grinding and jerking as plates slide past each other. Earthquakes - sudden movements of the Earth's crust that occur along faults where one rock mass slides past another ecological benefits - Soil formation, waste disposal, air and water purification, nutrient cycling, solar energy absorption, and biogeochemical and hydrological cycles all depend on biodiversity. We do not fully understand biological communities. Loss of a seemingly insignificant species can be damaging
