I need to correct that. Water from the ocean evaporates into the air, then moves over land to become rain. As the rain falls, it either runs along the surface as surface water, or sinks into the ground as underground aquifers or groundwater, what you see when you look down into an old fashioned well. Water on the surface becomes rivers, lakes, and streams. Streams flow into rivers. Lake water can flow into rivers, or sometimes rivers flow into lakes depending on the topography and stratigraphy.
Rivers that are damned up become man-made reservoirs which is usually where most water that is used by people comes from.
All other water, water in rivers, flow down and out back into the Ocean.
I have a degree in Geology.
