EXAMPLES IN GEORGIA
Appalachian Mountains- formed by plates pushing against each other
barrier islands- formed by wind, water, and waves moving sand and soil to new places
Cloudland Canyon- created by erosion from waterfalls and streams
Providence Canyon- formed by erosion of clay soil by rain
Amicalola Falls- causes erosion to the soil and rocks at the base of the falls and downstream
TECHNOLOGY
Dams- large concrete or earthen structures that regulate the flow of water
Levees- long earthen dikes or low walls to control flooding
Windbreaks- the planting of trees to limit wind erosion
Terracing- the practice of making multiple flat areas on a mountain side in order to control erosion from rainfall
Contour plowing- plowing a crop so that wind erosion is limited
UNIT TEST is tentatively scheduled for December 18th.
