Evaporati on Heat energy from the sun causes water in puddles, streams, rivers, seas, oceans or lakes to change from a liquid to water vapor (a gas). This is called evaporation. Eventually the vapor rises into the air and collects in clouds.
Transpiration Transpiration 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.
Condensation As water vapor rises and cools, it collects around dust particles (or condenses) and forms clouds.Water vapor (a gas) becomes liquid again. This is called condensation.
Precipitation When clouds are saturated gravity pulls the water to the earth. Mainly as rain, but sometimes as snow, sleet, and hail. This is called precipitation.
2 types of Run Off Surface run off: movement of water on Earth’s surface to collect in rivers, streams, lakes and oceans. Subsurface run off: movement of water beneath the Earth’s surface that eventually collects in aquifers and springs.
Infiltration occurs when the water moves from the surface into the soil. Then water percolates down through the soil. The rate of percolation depends on the type of soil.
Accumulation a.k.a. collection Water collects in rivers, lakes, streams, and the ocean.
Evaporation The vapor rises Condensation The Clouds form Precipitation The rain falls Transpiration The movement through plants Accumulation
