Earth's Structure and Movement Concepts

The video explores the formation of Earth, starting from the Big Bang to the development of continents. It explains why Earth and other 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, highlighting the crust, mantle, and core. The video also covers various landforms like mountains and deserts, and explains Earth's four domains: lithosphere, hydrosphere, atmosphere, and biosphere.
