5(1)EvaporationHeat energy from the sun causes water in puddles, streams, rivers, seas or lakes to change from a liquid to a water vapor.This is called evaporation.The vapor rises into the air and collects in clouds.
6(2)CondensationWater vapor collects in clouds. As the clouds cool the water vapor condenses into water drops.This is called condensation.These drops fall to the earth as rain, snow or hail.
7(3)PrecipitationWater falls to the earth from clouds. Mainly as rain, but sometimes as snow and hail.This is called precipitation.
8(4)TranspirationTranspiration is the process by which plants lose water out of their leaves. Transpiration gives evaporation a bit of a hand in getting the water vapor back up into the air.

14Carbon reservoirsParts of the Earth system where carbon is stored is called carbon reservoirs
15Carbon is taken from the atmosphere in several ways ①Photosynthesis.②The oceans when the seawater becomes cooler, more CO2 dissolve and become carbonic acid.In the upper ocean areas organisms convert reduced carbon to tissues, or carbonates.
223. The Energy CycleThe amount of energy that enters the system should equal the amount that is removed.Because of the balance-scale nature of Earth’s energy cycle, scientists also call it Earth’s energy budget.
23Three main sources of energy in Earth’s energy budget Solar EnergyGeothermal EnergyTidal Energy
24<The Law of Thermodynamics> Energy can never be created or destroyed, only changed from one form to another.When energy changes, it is converted from a more useful, more concentrated form to a less useful, less concentrated form.→Energy can never be recycled completely.
