Continental margins, just like plate boundaries, are areas of the Earth where there is much action while shaping our Earth today. Many of the largest mountain chains such as the Andes, Himalayas, and Rockies all are formed at continental margins. Orogeny is a term that describes the process of mountain building at these boundaries (Thompson, 217). A large influence on shaping the Earth is the weathering the mountains endure over time. The weathering affects different materials in the Earth and produces a different result in each case. Weathering of the Earth cannot be noticed in a short period of time, but over the course of the Earth’s existence, the world has changed drastically. Weathering is the process that decomposes rocks and converts them to loose gravel, sand, clay, and soil (Thompson, 233). Weathered material simply gathers where it is formed. The process of erosion then takes weathered rocks and minerals during heavy wind or rain. The process of these materials goes from originally weathering, to erosion, then to transport, and finally deposition where the rocks or minerals finally rest (Thompson, 233). The first type of weathering is mechanical or physical weathering.
