Which term describes land becoming desert-like due to environmental processes?

• A. Depletion
• B. Desertification
• C. Desalination
• D. Dieback

Answer: (B)

Desertification is the process by which land in dry regions becomes desert-like as a result of environmental processes such as drought, soil erosion and loss of vegetation, often made worse by human activities like overgrazing and deforestation. This term exactly describes land that is losing its productivity and becoming more barren, which is what the question is asking about. Depletion means running out of resources in general and isn’t specific to turning land into desert-like conditions. Desalination is the process of removing salt from seawater, not a land degradation process. Dieback refers to the death of plant parts or entire plants under stress, not the widespread transformation of landscape. So the term that best fits is desertification.
