delta - a fan-shaped deposit at the mouth of the stream. These deposits build up over time & change with erosion and deposition. Deltas form when flowing water carries a load of sediment particles, slows down, and is no longer able to its full sediment load. Falling sediments deposit (deposition) to form a fan-shaped deposit at the mouth of the stream. Over time, the deposit changes by further erosion & deposition.


erosion - a naturally occurring process on the earth's surface that transports weathered rocks and soil from one place to another. Erosion is a process that may be slow or alarmingly fast.


landform - characteristic physical shape on Earth's surface, such as hills, valleys, mountains, plains, marshes, and cliffs.




model - any representation of a system, or its parts, to help one study and understand how it works.


river channel - the depression in land through which a river flows.
