How did the natural forces shaped the land of the western hemisphere?

Natural forces such as tectonic activity, erosion, and weathering have profoundly shaped the land of the Western Hemisphere. Tectonic plate movements have created major mountain ranges like the Rockies and Andes, while volcanic activity has formed various landscapes, including the Pacific Ring of Fire. Erosion by rivers, glaciers, and wind has sculpted valleys, canyons, and plains, significantly altering the terrain over time. Together, these processes have contributed to the diverse ecosystems and geographical features found across the region.
