The law of altitudinal zones. It is general, but it has individual characteristics: altitudinal zonation manifests differently in various mountain ranges. Mountain and plain natural zones have similarities (general) and differences (individual). When ascending mountains, due to climate cooling, changes in natural zones will be observed, similar to movement from south to north across a plain.

This text describes the concept of altitudinal zonation, explaining that it's a general phenomenon but varies in different mountain ranges. It highlights that both mountains and plains have natural zones with commonalities and distinctions. The text further explains that as one ascends a mountain, climatic changes lead to shifts in natural zones, analogous to traveling from south to north on a plain.
