Physical Weathering: Physical Weathering Process by which rocks are broken down into smaller pieces by external conditions. Types of Physical weathering Frost heaving and Frost wedging Plant roots Friction and impact Burrowing of animals Temperature changesFrost Wedging: Frost WedgingFrost Heaving: Frost HeavingPlant Roots: Plant RootsFriction and Repeated Impact: Friction and Repeated ImpactBurrowing of Animals: Burrowing of AnimalsTemperature Changes: Temperature ChangesChemical Weathering: Chemical Weathering The process that breaks down rock through chemical changes. The agents of chemical weathering Water Oxygen Carbon dioxide Living organisms Acid rainWater: Water Water weathers rock by dissolving it Oxygen: Oxygen Iron combines with oxygen in the presence of water in a processes called oxidation The product of oxidation is rustCarbon Dioxide: Carbon Dioxide CO2 dissolves in rain water and creates carbonic acid Carbonic acid easily weathers limestone and marbleLiving Organisms: Living Organisms Lichens that grow on rocks produce weak acids that chemically weather rockAcid Rain: Acid Rain Compounds from burning coal, oil and gas react chemically with water forming acids. Acid rain causes very rapid chemical weatheringKarst Topography: Karst Topography A type of landscape in rainy regions where there is limestone near the surface, characterized by caves, sinkholes, and disappearing streams. Created by chemical weathering of limestoneFeatures of Karst: Sinkholes: Features of Karst: SinkholesFeatures of Karst: Caves: Features of Karst: CavesFeatures of Karst: Disappearing Streams: Features of Karst: Disappearing StreamsErosion: Erosion The process by which water, ice, wind or gravity moves fragments of rock and soil.Water Erosion: Water Erosion Rivers, streams, and runoffIce Erosion: Ice Erosion GlaciersWind Erosion: Wind ErosionMass Movements: Mass Movements Landslides, mudslides, slump and creep landslide clip.mpeg You do not have the permission to view this presentation.
