    Study Notes

    Water Cycle Processes

    • Water constantly changes between liquid and vapor
    • The water cycle circulates water between land, sky, and sea
    • Main processes: Evaporation, Condensation, Precipitation, Transportation

    Evaporation

    • Energy from the sun drives the water cycle
    • Sunlight warms the water surface
    • Water particles absorb energy, move faster
    • Particles escape the surface as water vapor

    Condensation

    • Upper part of the sky cools
    • Water vapor cools and condenses
    • Forms small water droplets
    • Droplets join to form clouds

    Precipitation

    • Water vapor condenses in clouds
    • Forms bigger water droplets
    • Droplets become heavy enough to fall as rain
    • In colder altitudes, droplets freeze to form ice

    Transportation

    • Clouds are carried by wind
    • Moved to other places

    Rate of Evaporation

    • Wet clothes dry faster when unfolded
    • Larger surface area exposed to air increases rate of evaporation
    • Other factors influencing evaporation rate: humidity, air temperature, air speed
