1 The Water Cycle aka The Hydrocycle QQ 1 – In your own words, what is the water cycle and why is it important?
2 water never leaves the Earth constantly cycles through atmosphere, ocean, and landthis process is known as the water cycledriven by energy from the sun - radiationcrucial to the existence of lifeQQ 2 – What are the three types of energy transference?
3 Step 1: Evaporation/Transpiration Solar energy warms cooler, heaver waterThrough the process of radiation, the warmed water becomes lighter, changes into a gas, and risesthis process is called evaporationWater evaporates from oceans, lakes, rivers, and moist soilEvaporated water rises into the atmosphere
4 The process of evaporation from plants is called transpiration The process of evaporation from plants is called transpiration. (In other words, it’s like plants sweating.)
7 Step 2: Condensation Water in the form of gas rises in the atmosphere begins to cool and become a liquid againThis process is called condensationClouds form when a large amount of water vapor condensesThis process is driven inpart by convection currents
9 Step 3: Precipitation Water becomes heavy as it collects in the clouds When water becomes too heavy, it will fall back to earthThis is called precipitationThis process is driven inpart by convection currents
11 When precipitation falls on the land, some is absorbed into the ground Step 4. RunoffWhen precipitation falls on the land, some is absorbed into the groundThis forms pockets of water called groundwaterMost groundwater eventually returns to the oceanOther precipitation runs directly into streams, rivers, lakes, oceans, etc.Water that collects is called runoff
