Definition
| most common and looks similar to a tree. Dendritic Drainage occurs where a region is above a single type of bedrock (homogeneous). Which gives the entire area a similar resistance to erosion and therefore a seemingly random placement of tributaries. Most tributaries will join a larger stream at an acute angle. |

Definition
| generally forms where there is a large hill. They develop in areas with parallel regions of rock that are harder to erode |

Term
| Trellis Drainage Patterns |
|
Definition
| form where there is a folded topography, like the Appalachian mountains. Tributaries enter the main stream at near right angles. |

Term
| Rectangular drainage patterns |
|
Definition
| found in regions that have undergone faulting. Streams follow the path of least resistance and thus are concentrated in places were exposed rock is the weakest. |

Term
|
Definition
| develop around a central elevated point. These patterns are common to such conically shaped features as volcanoes |
|
|
Term
| Centripetal drainage patterns |
|
Definition
| opposite of radial ones. They are common in basins like in the United States Southwest region, where streams flow downward to a central point. |
