which is a cause of desertification?\no farming\no creating reservoirs\no overgrazing\no driving motor…

Answer:

C. overgrazing

Brief Explanation:

Overgrazing removes vegetation, leaving soil vulnerable to erosion and degradation, which can lead to desertification. Farming can have impacts but not as directly desert - causing as overgrazing. Creating reservoirs can change local hydrology but not directly cause desertification. Driving motor vehicles mainly contributes to air pollution and has a minor direct link to desertification compared to overgrazing.
