Rift basin definition
In geology, a rift is a linear zone where the lithosphere is being pulled apart and is an example of extensional tectonics. Typical rift features are a central linear downfaulted depression, called a graben, or more commonly a half-graben with normal faulting and rift-flank uplifts mainly on one side. Where rifts remain above sea level they form a rift valley, which m… WebDec 23, 2010 · A river basin is normally a part of the land drained by the river and its tributaries. It is characterized by a flow of streams and creeks. A river basin acts like the arteries in our body that connects one part of the body to the other.
