In the inner part of the desert, weathering will be caused by wind, as there are little plants to hold the soil down, and the sand is picked up by the wind and carried along, scratching against rocks along the way. Erosion in the inner desert is also caused by wind; as stated earlier, the wind picks up the loose soil on the ground and carries it to a new location, where the wind will die down and the soil will be dropped, eventually forming sand dunes.
On the coastal area of the desert, weathering is caused by the constant beating of the waves on the rocky shore, slowly breaking the rocks apart. The waves and the wind both pick up the new soil, and the weathered rock is eventually deposited either to the bottom of the ocean or a new sand dune.
The mountainous terrain of the Atacama allows for streams to erode away soil during the rare occasions when it rains, and it also allows for wind to deposit soil along the mountain, making it larger bit by bit over time.
