Earth has four spheres that all have their own distinct differences. The lithosphere or geosphere is a sphere made up of rocks, minerals, and landforms. Nothing in the geosphere is alive. The hydrosphere includes all water on earth (Groundwater, ice, salt water, fresh water, rain, snow, and glaciers). The biosphere includes all living things (Plants, animals, fungi, and bacteria) and is made up of biomes. The atmosphere holds all of the gases on earth. The atmosphere is split between 5 layers (the troposphere, stratosphere, mesosphere, thermosphere, and exosphere).
