Document Summary
Weak surfaces for landslide, earthquake, and failures of infrastructure. Unconformity: contact structure of rocks representing geologic time gap in the geologic record, an ancient erosion surface. The process by which rocks and minerals breakdown at the earth"s surface due to physical, biological, and chemical processes. Leads to the formation of the soils. Transformation of feldspar minerals into clay minerals. Reduction in size of rocks and mineral grains. Consumption/ modification of minerals through biologic activity. Study of relationships between living things and their environments; the study of controls over the distribution, abundance and health conditions of living things. Study of geological processes and their effects on the environment. Species: a group of individuals capable of interbreeding. Population: a group of individuals of the same species living in the same area. Community: a group of popul different species living in the same area.
