Question

1. which of the following best describes the relationship between erosion and deforestation? a. deforestation prevents erosion b. erosion causes deforestation c. deforestation increases erosion d. they are unrelated 12. what is one way urbanization can affect water systems? a. it increases water purity b. it reduces water runoff c. it increases pollution in waterways d. it prevents flooding 13. which practice helps prevent desertification? a. overgrazing b. crop rotation c. deforestation d. urban expansion 14. which of the following is a consequence of erosion? a. soil fertility increases b. land becomes more stable c. loss of topsoil d. increased vegetation 15. what is one environmental effect of rapid urbanization? a. increased forest cover b. decreased greenhouse gas emissions c. habitat destruction d. improved biodiversity 16. which human activity most directly leads to deforestation?

Explanation:

1. Trees help hold soil in place. Deforestation removes trees, increasing the likelihood of soil erosion.
2. Urbanization often involves paving land, which increases runoff and can introduce pollutants into waterways.
3. Crop rotation helps maintain soil health and fertility, preventing soil - related issues that can lead to desertification. Overgrazing, deforestation, and urban expansion contribute to desertification.
4. Erosion wears away the top layer of soil, which is rich in nutrients. This leads to loss of topsoil.
5. Rapid urbanization involves building infrastructure on natural land, which destroys habitats for many species.
