Exploring Earth's Geography: Continents and Glaciers

The video explores the concept of Pangea and the theory of continental drift, explaining how Earth's continents were once a single supercontinent. It delves into plate tectonics, describing how tectonic plates move and interact to shape Earth's surface. The video also provides an overview of the seven continents, highlighting their unique features. It discusses Earth's landforms, including mountains, plains, and plateaus, and explains the processes that form them. The four domains of Earth—lithosphere, hydrosphere, atmosphere, and biosphere—are examined, emphasizing their roles in supporting life. The video concludes with discussions on glaciers and climate change, and the characteristics of the tundra biome.
