We know it exists because we deal with temperature. • 4 Layers: • Troposphere (0-14 km): Most Dense, weather systems take place here. • Stratosphere (15-50 km): Ozone layer. Mesosphere (58-85 km): Temperature is going down as you move up towards the surface • of the Earth. • Thermosphere (90-500 km): Upper atmosphere. 3 States of Water • Solid, liquid, gas • Gas —> liqui
