What rock dominates Yosemite Valley and is one of the earths most common igneous rock?

The rock that dominates Yosemite Valley and is one of the Earth's most common igneous rocks is granite. Granite is an intrusive igneous rock that forms when magma cools and solidifies below the Earth's surface. It is composed primarily of quartz, feldspar, and mica. Granite is a hard, durable rock that is resistant to weathering and erosion, which is why it is so common in Yosemite Valley. The valley was formed by glaciers that carved out the soft rock, leaving behind the more resistant granite cliffs and domes.
