Erosion is a movement of rock and land that makes new land.  Weathering helps by breaking down rock into smaller pieces.  Erosion happens just by water and wind most of the time. It wears away the Earth's surface little by little.  Erosion has five drainage patters they are Dendrites, Annular, Trellis, Radial, and Rectangular.

Five Drainage Patterns

            Rectangular Drainage                                           Dendritic Drainage                                                                                                                                                                       

Trellis Drainage                                                        Annular  Drainage               

                 Radial  Drainage

Deposition happens just like erosion. Deposition transports sediments in new location. Physical weathering is breakdown rock without chemical composition. The difference between erosion is a movement rock and weathering breakdown rocks. Erosion affect the world by making trees going in the ground, but it form new land. The agents of erosion an agent is mostly cause by gravity. Erosion happens in valleys and canyon. Human activity effect landscape farming, construction, logging, and mining can affect landscape. Erosion can happen an time if you was on valley or canyon. Physical weathering happen rain and wind. Weathering is just like physical weathering.   Weathering breakdown rocks into clay or  sand
