Which term describes the process by which fertile land becomes desert?

• A. Light bulb
• B. Desertification
• C. Endanger
• D. Shelter

Answer: (B)

Desertification is the process by which fertile land becomes desert. It happens when drought and climate variability combine with unsustainable land use—like deforestation, overgrazing, and poor farming practices—that erode soil, strip away nutrients, and degrade soil structure. When soil loses its ability to hold water and support vegetation, plant life dwindles, erosion increases, and the land becomes less productive. Over time, these effects expand desert-like conditions into areas that were once fertile, especially in semi-arid regions where rainfall is already limited. The other options don’t describe this environmental change: one is a device for lighting, another means to threaten, and another refers to a place of protection.
