Question

what is desertification?
land becoming more fertile
expansion of fertile land
land becoming more desert - like
increase in water availability

Explanation:

Desertification refers to the process where land transforms to have more desert - like characteristics, such as reduced vegetation, increased aridity, and loss of soil fertility. The first option (land becoming more fertile) is the opposite of desertification. The second option (expansion of fertile land) also goes against the concept. The fourth option (increase in water availability) is not related as desertification is associated with less water availability. Only the third option (land becoming more desert - like) matches the definition of desertification.

Answer:

C. land becoming more desert - like (assuming the third option is labeled C; if the original options had labels like A, B, C, D, adjust the label accordingly. Based on the given options, the correct one is "land becoming more desert - like")
