Final answer:
Precipitation is the process that allows water to move from the atmosphere into a body of water like a lake or ocean.
Step-by-step explanation:
The process that allows water to move from our atmosphere into a body of water like a lake or ocean is precipitation. When water vapor condenses into clouds, it eventually falls back to the Earth's surface as rain or snow. This precipitation can then enter freshwater bodies like lakes or infiltrate the soil and eventually make its way back to the ocean.
