Course Introduction
Dynamic Earth Systems explores the complex and interconnected processes that shape our planet, including the movement of tectonic plates, the rock cycle, and the interactions between the atmosphere, hydrosphere, biosphere, and geosphere. Students will examine how internal and external forces drive changes in Earths structure and surface over time, influencing landscapes, ecosystems, and climate. The course emphasizes scientific methods used to study Earths dynamics and encourages critical thinking about natural hazards, resource management, and the impact of human activities on global systems.
