Rivers form from precipitation such as rain or snow that collects and flows downhill due to gravity, initially forming small streams. These streams merge with other streams, increasing in size, and eventually form a river as they continue to flow towards lower elevations, often emptying into a larger body of water like an ocean, sea, or lake.
