Mr. Goldberg-George Herbert
Here you see the sun, which drives the water cycle, heats liquids such as water in the oceans with its solar radiation. Some of it evaporates as vapor into the air.
Rising air currents take the gas up into the atmosphere, along with water from evapotranspiration, which is water transpired from plants and evaporated from the solid soil. The vapor rises into the air where cooler temperatures cause it to condense into clouds.
Air currents move clouds around the globe, cloud particles collide, grow, and fall out of the sky as precipitation. Right now, it is raining.
This type of precipitation doesn't really occur very often here because of the heated climate and immense amount of thermal energy.
Some precipitation can fall as snow, sleet, and even hail!
Most precipitation falls back into the oceans or onto land, where, due to gravity, the precipitation flows over the ground as surface runoff. A portion of runoff enters rivers in valleys in the landscape, with stream flow moving water towards the oceans.
Runoff, and groundwater seepage, accumulate and are stored as freshwater in lakes. Not all runoff flows into rivers, though. Much of it soaks into the ground as infiltration.
