Igneous Rocks:
* Granite: A hard, light-colored rock formed from slowly cooling magma deep underground. It's often found in mountain ranges like the Sierra Nevada.
* Basalt: A dark, dense rock formed from quickly cooling lava flows. It's found in volcanic mountains and plateaus.
* Rhyolite: A light-colored, volcanic rock similar to granite but formed from quickly cooled lava.
Sedimentary Rocks:
* Sandstone: Formed from cemented sand grains, often found in mountains formed from eroded older rocks.
* Limestone: Formed from the accumulation of marine organisms' shells and skeletons. It's often found in mountains formed from ancient coral reefs.
* Shale: A fine-grained rock formed from compressed mud and silt. It's commonly found in mountains formed by folding and faulting of the earth's crust.
Metamorphic Rocks:
* Marble: Formed from metamorphosed limestone, often found in mountains formed by tectonic collisions.
* Quartzite: Formed from metamorphosed sandstone, often found in mountains formed by tectonic collisions.
* Schist: Formed from metamorphosed shale, often found in mountains formed by tectonic collisions.
The specific type of rock a mountain is made of depends on the geological history of the area and the processes that formed the mountain.
For example, mountains formed by volcanic activity will typically be made of igneous rocks like basalt or rhyolite, while mountains formed by tectonic collisions will often be made of metamorphic rocks like marble or schist.
Some mountains can even be made of a mixture of different rock types.
