These spheres contribute to life on earth. The lithosphere is made up of all the rocks on earth, including the mantle and crust. The lithosphere is split into tectonic plates. The hydrosphere is all of the water on earth. This includes rivers, lakes, oceans, and underground water. The biosphere is all living organisms. This includes plants and animals and one-celled organisms. The atmosphere includes the gases that surround the earth. It is divided into four zones: troposphere, stratosphere, mesosphere, thermosphere, and exosphere. ]]> 2022-04-19 15:43:01 UTC https://padlet.com/mc0320450/u9csw7iith8pqs4z/wish/2148810393
