Glacial erosion formed Yosemite Valley. Meanwhile, the streams eroded the granite rock to form the waterfalls we know as Yosemite Falls and many others today.

Granite rock makes up the majority of Yosemite's geological features. Rock fall occurs fairly frequently in the valley and rock climbers must take caution when going up.
Sand dunes are formed by wind, which is one kind of erosion.

Valleys are formed by glaciers through a process called glacial erosion. As glaciers move, they pick up rocks and debris, which act as tools to scrape and carve the underlying bedrock. Over time, this erosion deepens and widens the valley, creating the distinctive U-shape commonly associated with glacial valleys.
Sea arches and seastacks
El Capitan is a vertical granite rock formation located in Yosemite National Park in the United States. It is a natural boundary that separates Yosemite Valley from the higher elevations of the Sierra Nevada mountains.
sedimentary rock formed by weathering and erosion
Sedimentary rock is formed by the processes of weathering, erosion, and deposition. These rocks are made up of sediments that have been compacted and cemented together over time.
Soil can be formed from the erosion and deposition of any kind of rock: igneous, sedimentary, or metamorphic.
