Earth Science Concepts and Processes

The video explores the formation of Earth, starting from the Big Bang to the creation of Pangaea and modern continents. It explains why planets are round due to gravity and discusses Earth's rotation and revolution, which cause day, night, and seasons. The structure of Earth is detailed, covering the crust, mantle, and core. The video also examines various landforms like mountains, plateaus, and deserts, and their formation processes. Finally, it describes Earth's four major domains: lithosphere, hydrosphere, atmosphere, and biosphere, which support life.
