Erosion

"Erosion is the process by which natural forces move weathered rock and soil from one place to another." Erosion at North Cascades National Park can be seen anywhere. However, one major example is the widening of the Skagit River. This occurs because river and rain water moves the soil, and other substances along the banks, downstream. This process will eventually make this valley wider.

Weathering is also common at this park. "Weathering occurs when certain things like water, ice, plants,etc. break down rocks." The reason weathering is common at the North Cascades is there is an abundance of glaciers, snow, and ice in certain areas. The photo on the left shows how weathering can break down rocks.
Deposition

"The deposition process takes place where the agents of erosion lay down sediment, which changes the shape of the land." At North Cascades National Park, deposition occurs at different bodies of water such as the Skagit River. This process starts with glaciers because glaciers consist of soil, rock, and other sediments. After that, as a result of climate change, glaciers melt. When these glaciers melt, these sediments run off into different bodies of water and come to rest there.
