Transcript of Weathering, Erosion, and Human Impact on the Surface of the Earth

By Marrs Griggs and Brendon Jean-Baptiste Weathering, Erosion, and Human Impact on the Surface of the Earth Weathering Erosion Deposition How Weathering and Erosion Affect Where Humans Build Businesses and Homes Effects of Weathering, Erosion, and Deposition on the Surface of the Earth How Humans Prevent Negative Effects of Weathering, Erosion, and Deposition on the Surface of the Earth How Humans Cause Negative Effects of Weathering, Erosion, and Deposition on the Surface of the Earth Weathering is the process of breaking down rocks into sediment
Mechanical weathering is the changing of the size and shape of a rock
Chemical weathering is the changing of the chemical composition of a rock
An example mechanical weathering includes water that freezes and expands in cracks of rocks
An example of chemical weathering includes acid rain which corrode rocks Erosion is the moving of sediment
An example of erosion includes wind picking up sand and moving it to another location Nile Delta Humans will build farms on flood plains because of the rich soil
Humans avoid building homes on cliffs that have been weakened by weathering and erosion
Humans avoid building homes and businesses in deserts as erosion can cover them with sand Humans build dams to prevent water from weathering and erosion the landscape
Humans plant plants to keep soil in place and prevent soil erosion
Humans plant trees to block the wind from weathering and eroding Humans fill in wetlands that help prevent water erosion
Humans cut down forests that hold soil in place
Humans heat up up the Earth which melts glaciers and make them move faster and pick up more rocks or create water which weathers and erodes the landscape Sources http://www.ehow.com/info_8430062_negative-effects-weathering-erosion.html
