weathering and erosion
weathering- wear away or change the appearance o texture of something by long exposure to the air.
physical weathering- the geological process of rocks breaking apart without changing the chemical composition.
frost wedging - caused by the repeating freeze thaw cycle of water in extreme climates
chemical weathering - the erosion of disintegrating of rocks and buildings materials
acid precipitation - including rain, snow, hail, fog, or dew, that is high in acid pollutants, especially sulfuric and nitric acid.
PH scale - Mixing acids and bases can cancel out or neutralize their extreme effects.
erosion-the process of eroding or being eroded by wind, water, or other natural agents.
soil-the upper layer of earth in which plants grow, a black or dark brown material typically consisting of a mixture of organic remains, clay, and rock particles.
sand -a loose granular substance, typically pale yellowish brown, resulting from the erosion of siliceous and other rocks and forming a major constituent of beaches, riverbeds, the seabed, and deserts.
silt-fine sand, clay, or other material carried by running water and deposited as a sediment, especially in a channel or harbor.
clay-a stiff, sticky fine-grained earth, typically yellow, red, or bluish-gray in color and often forming an impermeable layer in the soil. It can be molded when wet, and is dried and baked to make bricks, pottery, and ceramics.
groundwater-water held underground in the soil or in pores and crevices in rock.
watertable-the level below which the ground is saturated with water.
zone of saturation - The phreatic zone, or zone of saturation, is the area in an aquifer, below the water table, in which relatively all pores and fractures are saturated with water.
zone areation -The zone of aeration is the region between the earth's surface and the water table. The main components of this region are the soil and rocks.
surface water- water that collects on the surface of the ground.
infiltration - the action of entering or gaining access to an organization or place surreptitiously, especially in order to acquire secret information or cause damage.
river basins -A river basin is the portion of land drained by a river and its tributaries
aquifers -a body of permeable rock that can contain or transmit groundwater.
watersheds -an area or ridge of land that separates waters flowing to different rivers, basins, or seas.
flooding-cover or submerge (a place or area) with water.
landslides-the sliding down of a mass of earth or rock from a mountain or cliff.
tsunami -a long high sea wave caused by an earthquake, submarine landslide, or other disturbance.
sinkhole-a cavity in the ground, especially in limestone bedrock, caused by water erosion and providing a route for surface water to disappear underground.
pollution- the presence in or introduction into the environment of a substance or thing that has harmful or poisonous effects.
porosity-Porosity or void fraction is a measure of the void spaces in a material, and is a fraction of the volume of voids over the total volume
barrier island -a long narrow island lying parallel and close to the mainland, protecting the mainland from erosion and storms.
