01 What is the main subject matter of human geography?
Answer and explanation
Correct answer: A. Interaction between humans and environment
Explanation: The governing concept is the reciprocal human–environment relationship. Human beings depend on environmental conditions, adapt to them and use knowledge and technology to modify surroundings; at the same time, those modifications can produce benefits or environmental pressures. Therefore, option A correctly identifies the main subject matter. Options B, C and D focus on selected physical-geographical processes—landforms, ocean currents and atmospheric events. These are important fields, but none alone represents the central concern of human geography. A complete answer should connect human activities with place, resources, environment and spatial organisation rather than treating society and nature as completely separate.
