  4. Geo-sphere- • The rocky part of Earth • Goes from center of Earth to the surface • Divided into 3 layers: crust (least dense), mantle, and core (most dense) land • Bio-sphere- life • life is found almost everywhere on earth- in soil, lakes, and even on rocks • most life needs oxygen or carbon dioxide to survive • most also need liquid water and moderate temperatures • the sun is the original source of energy for all life on earth • Atmo-sphere- air • The invisible gas surrounding earth • About 600km high, but most gases are near earth’s surface • 78% of the gas is nitrogen • Atmosphere reflects and absorbs some harmful UV rays Earth’s 5 Spheres • Hydro-sphere- • Includes lakes, rivers, marshes, clouds, rain, and underground water • 97% of all water is salt; oceans cover 70% of Earth’s surface • The water cycle is how water moves on, above and below earth liquid water • Cryo-sphere- frozen • All the frozen water on earth • Mostly in Antarctica and the Artic • Includes snow, glaciers, sea ice, icebergs, and even frost in the ground • Amount changes with the seasons
