Land used for growing crops, only 1 third or earths land is fertile. The rest is to wet and salty. New land is destroyed by destroying forests, draining wet lands, and iragating deserts.

Removal of non-renewable resources. Strip mining is removal of an intire strip of land. You must replace everything after strip mining. If not you create dangerous holes and collapse surfaces.

Construction of buildings. 2.5 acres is developed each year. Destroys land and needed wildlife

Problems with poor soil managment

Erosion- Process in which wind and water move land and destroy rock can be reduced with soild conversion

Nutrient depletion- Lack of needed nutrients in soil. Becomes infertile by lack of nutrients to prevent rotate crops allow root and leave fallow land

Advance of desert like condition if fertile soil, happens when there is a giant change in the climate overgrazing animals, or extreme lack of trees.

Alternate tall and short crops, prevents soil washout

Curved rows around a hill prevents soil erosion

Leave dead plants in there place to hold topsoil

Build land into flat ridges of soil, prevents soil erosion

Rows of trees along edge of field to break wind, prevents soil erosion

dead leaves and grass and organic material

Mixture of rock fragments,nutrients, water and air.

Mixture of lots of rock fragments, a little bit of water, and a bit of air

Rock that makes up earth's crust that is destroyed by freezing

Question	Answer
Agriculture	Land used for growing crops, only 1 third or earths land is fertile. The rest is to wet and salty. New land is destroyed by destroying forests, draining wet lands, and iragating deserts.
Mining	Removal of non-renewable resources. Strip mining is removal of an intire strip of land. You must replace everything after strip mining. If not you create dangerous holes and collapse surfaces.
Development	Construction of buildings. 2.5 acres is developed each year. Destroys land and needed wildlife
Problems with poor soil managment	Erosion- Process in which wind and water move land and destroy rock can be reduced with soild conversion
Porr soil managment	Nutrient depletion- Lack of needed nutrients in soil. Becomes infertile by lack of nutrients to prevent rotate crops allow root and leave fallow land
Desertification	Advance of desert like condition if fertile soil, happens when there is a giant change in the climate overgrazing animals, or extreme lack of trees.
Strip cropping	Alternate tall and short crops, prevents soil washout
Contour Plowing	Curved rows around a hill prevents soil erosion
Conversion Plowing	Leave dead plants in there place to hold topsoil
