Pacific and Northern plates crashed against each other and cause the sierra Nevada mountains form
granite and many other rocks

sierra foothills
Intrusive igneous rocks, like granite.
Where tectonic plates collide, the intervening crust can be folded or pushed up to form mountains. In the case of the Sierra Nevada, an ancient collision forced magma from an oceanic plate beneath the western part of North America. After millions of years, erosion and glaciation has exposed these underground rocks, or plutons, which form the bases of the mountains of the range.
granite is all that i know of.
The majority of Earth's crust is composed of igneous rocks, particularly basalt and granite. These rocks form through the cooling and solidification of molten material from beneath the Earth's surface.
yes the entire mountain range used to be volcanoes
Igneous, examples include Granite and Basalt
These are igneous rocks. They may form from lava at the Earth's surface, like basalt, or from magma beneath the ground, like granite.
Rocks that form as a result of cooling magma are igneous rocks. They can be classified as intrusive rocks (cooled slowly beneath the Earth's surface) or extrusive rocks (cooled quickly at the Earth's surface). Examples include basalt, granite, and rhyolite.
