Document Summary
Water is an important agent of erosion & sediment transported on earth. River channels & river deltas are examples of . Sand dunes are an example of an . The size, shape, & orientation of sand dunes can provide a great deal of info about the. Involve transport of fine-grained material by wind. Earth is the only planet that has abundant liquid water on its surface today, but evidence suggests that this wasn"t always the case. Many of the types of landforms formed or shaped by water on earth today can be found preserved on the surface of mars. & deltas ( distributary networks ) are all common landforms produced by water on earth that are easily recognizable in aerial or satellite photos floodplain. The maximum flow velocity (maximum erosion) occurs at the outside of each meander. The flow at the inside edge is slower, & the deposition of a point bar results.
