Topic: Rivers of the Solar System
"A river is a channel system constructed by naturally flowing liquids moving towards an ocean, sea, lake or another river. Rivers create diverse drainage patterns and a stunning variety of erosional and depositional landforms that provide important clues to the climate and geological framework of the landscape. Active rivers flow on Earth and Titan and ancient rivers are common on Mars and Venus. Rivers on the rocky planets are created by water flowing over rock or sediment but on Titan the rivers consist of liquid hydrocarbons eroding a crust of water ice."
