Water moving through the soil
Water running across the Earth’s surface
Water stored in underground aquifers
Some surface runoff evaporated the rest will infiltrate or flow down watercourses such as rivers
Water evaporated from plants through the leaves
Solar energy converts liquid water into water vapour to be stored as clouds
Water returning to the cycle usually as rainWater stored
