Explanation
Deforestation is a primary cause of soil erosion because the removal of vegetation leaves topsoil vulnerable to being washed away by rain or blown away by wind. Terrace cultivation is actually a soil conservation technique designed to prevent erosion on hilly slopes, which logically eliminates any option containing statement 1. The core concept tested is the distinction between human-induced causes of land degradation and the methods used for soil management and conservation.
