What is the basis for the formation of a natural complex?

Solution:

• The question asks about the fundamental basis for the formation of a natural complex.
• A natural complex is a territorially coherent and relatively stable combination of interacting components of nature: climate, relief, soil, rocks, water bodies, flora, and fauna.
• The interaction of all these components is what drives the formation and development of any natural complex.
• Relief, climate, and human activity are important factors that influence natural complexes, but they are not the sole basis for formation. The interconnectedness and interdependence of all elements are key.

Answer: Interaction of all components of nature
