WEATHERING The process of rock breaking down into smaller pieces
AGENTS OF WEATHERING • PHYSICAL AGENTS • (Physical Changes) • Glaciers • Animals • Ice • Ocean Waves • Plant Roots
CHEMICAL AGENTS OF WEATHERING • Plant Acids • Acid Rain • Oxidation • (CHEMICAL CHANGES)
EROSION Process of weathered rocks being carried away
AGENTS OF EROSION • Main force: gravity • Sediments removed & carried by glaciers, wind, water, and gravity (agents) • Moving glaciers smooth and polish rock below • Wind moves loose sand, silt & clay • Moving sand sandblasts a surface • Most important agent of erosion is running water • Particles carried by stream called the load
DEPOSITION Process of sediments settling in a new location
JOURNAL ENTRY 1/28/2013 • What would be the result to a topographical map after a forest fire? • What would be the result to a topographical map after a landslide? • Is all erosion bad for the earth?
