Transport- large networks of roads and train tracks
Agricultural- open land used for crops

3. Urbanization
The growth of urban areas is caused by people moving into cities.
When an area becomes urbanized, its natural land surface is replaced by buildings, parking lots, and roads
Roads and trains are often highly concentrated in urban areas
Urban areas have dense human populations

4. Why is soil important?
Provides habitats for organisms, such as plants, worms, bacteria, etc.
Provides water and nutrients for organisms
It is important in land ecosystems
It is important in agricultural land

5. How do humans affect land and soil?
Land degradation: the process by which human activity and natural processes damage land to the point that it can no longer support the local ecosystem
Urban sprawl: when urbanization occurs at the edge of a city or town. Forests, fields, and grasslands are replaced with houses, roads, schools, etc.
Erosion: when sediment is moved from one place to another by wind, water, and gravity. Erosion speeds up when land is degraded.
Urban sprawl decreases the amount of farmland and natural resources available.
It causes rainwater to runoff the hard surfaces into storm drains instead of back into the ground. This can increase erosion of nearby soil.
Roots of trees and plants act as anchors to the soil. When removed, the soil is exposed to wind and water

6. How do humans affect land and soil?
Nutrient depletion and land pollution: when nutrients in soil is used up and pollution from industrial activities damage land
Desertification: when land becomes more desert-like and unable to support life
Deforestation: the removal of trees and other vegetation. During urbanization, forests are replaced with buildings. Less plants and trees can lead to soil erosion
