    Study Notes

    Water Cycle Processes

    • Water constantly changes between liquid and vapor
    • This cycle occurs between land, sky, and sea
    • Main processes shown in the diagram include evaporation, condensation, precipitation, and transportation

    Evaporation

    • Driven by solar energy
    • Sunlight warms water surfaces
    • Water particles near the surface absorb energy
    • Particles move faster and escape the surface
    • Water changes from liquid to vapor

    Condensation

    • Cooler air causes water vapor to cool down
    • Vapor changes from gas to liquid
    • Small water droplets form
    • Droplets combine to create clouds

    Precipitation

    • When water droplets or ice crystals in clouds get too heavy
    • They fall to the earth as rain or snow
    • Water returns to land, rivers, and seas

    Transportation

    • Winds carry clouds to other locations
    • Movement of clouds by wind

    Water Cycle Summary

    • Water continuously circulates between land, sky, and sea
    • Water changes its state (liquid, vapor)
    • Key processes: Evaporation, condensation, precipitation, transportation

    Additional Information (Practical Application)

    • Wet clothes dry faster when unfolded
    • Larger surface area allows more evaporation
    • Other factors impacting evaporation rate include humidity, temperature, and air speed
    • Diatomite bath mats quickly absorb and evaporate water due to a large surface area of tiny pores
