Exogenic Processes - Geological activities and processes that start from outside, on the Earth's surface., Weathering, Erosion, Transportation, Deposition, and Mass Wasting or Movement - Common examples of Exogenic Process:, Weathering - Process by which rocks disintegrate or break into smaller pieces., Physical, Chemical, and Biotic Weathering - Three types of Weathering:, Physical Weathering - Rocks only change in appearance but not in chemical composition., Pressure, Temperature, Water, and Ice - Factors affecting Physical Weathering:, Block Disintegration, Exfoliation, and Frost Weathering - Examples of Physical Weathering:, Block Disintegration - Breaking down of rocks, block by block, because of repeated heating and cooling., Heating - This causes rocks to contract in Block Disintegration, Cooling - This causes rocks to expand in Block Disintegration., Exfoliation - Is the stripping away or peeling off of the outer layers of rocks due to intense heating., Frost Weathering - This happens in cold regions and occurs when a rock has cracks and water enters those cracks., Chemical Weathering - Is the disintegration of rocks due to the formation of new substances which is caused by chemical reactions., Oxidation, Carbonation, and Solution - Examples of Chemical Weathering:, Oxidation - Is the process in which oxygen reacts with the rock and causes changes in its chemical composition., Carbonation - Happens when Carbon Dioxide reacts with rainwater to form carbonic acid., Carbonic Acid - This dissolves some rock-forming minerals which causes rocks to break in Carbonation.., Solution - The process where water directly dissolves the minerals in rocks., Biotic Weathering - Is the disintegration of rocks caused by living organisms., Plants and Human Activity - Examples affecting Biotic Weathering:, Erosion - Is the geological process in which Earth materials are worn away and transported by natural forces such as wind or running water., Liquid Water, Wind, or Ice - Most Erosion is performed by:, Sediment - The transported material in Erosion is called, Soil, Wind, and Water Erosion - Three types of Erosion:, Soil Erosion - Is a gradual process that occurs when the impact of water or wind detaches and removes soil particles, causing the soil to deteriorate., Wind Erosion - It detaches soil particles and transports them by wind., Sandstorms - This is an example of Wind Erosion, Water Erosion - Is the removal of soil by running water which creates tiny channels like streams and waterways., Sheet, Rill, and Gully Erosion - Three types of Water Erosion:,
