Document Summary
Chapter 1: the nature of geology isn"t just the study of rocks. Use science to make observations, questions, imagination. 1. 1- how does geology influence our lives: where we live, where we get our resources (energy and materials, controls landforms. Napa earthquake- magnitude 6. 0 (can be predicture of a bigger earthquake. Landslides oso (march 22)- steep slopes and too much rain fall. A)- fault lines, volcanos, steep slopes (landslides), rivers (flood hazards), water supply, soil and nutrients (controlled by rock type and water) Goal: use the past to predict the future coming) Yet: rock types are dependent on age (time) Continant- usually bigger than what we see- shore lines count as contient. Ocean- some parts of seafloor is simple, while others have more complex history. Iron mines- old rocks because of change in atmosphere. Copper mines- young rocks continetal crest- granite and thick. Oceanic crests- basalt ( lava rock) and thin. Glaciers, rivers, lakes, steep mountain fronts, sand dunes, beach, offshore.
