Why does erosion always lead to depositon?

Answer 1

Erosion always leads to deposition because when the movement of sediments occurs, they have to settle down; they do not disappear into thin air. Erosion cannot last forever for one piece of rock; it cannot continuously be moved without stopping. It has to be deposited somewhere. One example is the Antelope Canyon. It was a piece of land called Navajo (Tribal Park). Flashfloods caused the erosion and made a beautiful canyon. The sediments swept away formed other parts of high land "elsewhere." Another example is the Grand Canyon. People have guessed that water eroded the land (primarily) and also wind.[Some people say] the areas that were deposited were inbetween some areas of the Grand Canyon(called The Grand Canyon Supergroup?), touching the Schists.

Answer 2

Erosion involves the movement of sediments, which get carried away by wind, water, or ice. Once the energy of the transporting medium decreases, the sediments settle and deposit in a new location. This process of deposition occurs as the transporting medium loses its ability to keep the sediments in motion.
