Course Introduction
Physical Geography explores the dynamic processes and natural features that shape the Earths surface, including landforms, climates, soils, vegetation, and water systems. This course examines the interactions between the atmosphere, hydrosphere, lithosphere, and biosphere, emphasizing the patterns and processes that influence weather, climate change, natural hazards, and ecosystems. Students will develop analytical skills through map interpretation, field observations, and case studies, gaining a deeper understanding of how physical environments impact human activity and vice versa.
