How long does erosion and transportation take?

Answer 1

Erosion is defined as the removal of soil, sediment, regolith, and rock fragments from the landscape. Most landscapes show obvious evidence of erosion. Erosion is responsible for the creation of hills and valleys. It removes sediments from areas that were once glaciated, shapes the shorelines of lakes and Coastlines, and transports material downslope from elevated sites. In order for erosion to occur three processes must take place: detachment, entrainmentand transport. Erosion also requires a medium to move material. Wind, water, and ice are the mediums primarily responsible for erosion. Finally, the process of erosion stops when the transported particles fall out of the transporting medium and settle on a surface. This process is called deposition.

Technically, the entire process could take hundreds of years. Maybe even thousands.
