Physical Geography

Exam Preparation Guide

Course Introduction

Physical Geography explores the natural features and processes that shape the Earths surface, including landforms, climate, vegetation, soils, and water systems. This course examines the complex interactions between the atmosphere, hydrosphere, lithosphere, and biosphere, helping students understand the dynamic systems that govern our planets physical environment. Through analyzing maps, satellite imagery, case studies, and fieldwork, students will gain insight into topics such as plate tectonics, weather patterns, biomes, and human impacts on the environment. The foundational knowledge from this course provides the tools necessary for further study in environmental science, ecology, and earth sciences.
