Our Planet

The video tutorial explains the different components of Earth, including the biosphere, hydrosphere, atmosphere, and geosphere. The biosphere encompasses all living things, while the hydrosphere includes all water bodies. The atmosphere is the gaseous layer surrounding Earth, and the geosphere is the solid, non-living part of the planet.
