Question

in order to build malls, neighborhoods, and offices, u.s. land developers had to remove the vegetation from building sites. over time, clearing vegetation from the land can damage the environment by causing a loss of topsoil. this process will most likely result in which of the following?

a. desalinization
b. extinction
c. desertification
d. urbanization

Explanation:

Analyze the environmental process

The question describes a scenario where land developers clear vegetation from building sites to construct malls, neighborhoods, and offices. This clearing of vegetation leads to a loss of topsoil over time. We need to identify the environmental consequence of this process. This relates directly to Human Impact on Ecosystems and Urbanization Effects.

Evaluate the options

• A. desalinization: This is the process of removing salt from seawater, which is unrelated to topsoil loss from land clearing.
• B. extinction: While habitat destruction can lead to extinction, the specific physical degradation of the land due to topsoil loss is more directly described by another term.
• C. desertification: This is the process by which fertile land becomes desert, typically as a result of drought, deforestation, or inappropriate agriculture (including vegetation removal and subsequent soil erosion/loss of topsoil).
• D. urbanization: This is the societal process of land development itself, which causes the vegetation clearing, rather than being the environmental result of the topsoil loss.

Formulate the conclusion

The loss of vegetation removes the root systems that hold soil in place, leading to severe soil erosion and loss of fertile topsoil. Over time, this degradation of fertile land into dry, unproductive land is known as desertification.

Answer:

• A. desalinization
• B. extinction
• C. desertification (Correct answer)
• D. urbanization
