Do you know where the highest waterfall in North America is? Do you know where the mountains still grow 1 foot every 1000 years? Both of these facts are true in Yosemite National Park.
Yosemite National Park is Located in the southern Sierra Nevada Mountains of California.

The park’s granite is made up of smaller bodies of granite. This is one reason why there are many varieties of granite. Weathering of exposed granite is slow because weathering depends on whether there is moisture or not. Edges and corners of joint granite blocks are more affected when weathering occurs. Unweathered remains of granite turns into rounded boulders. Small natural depressions turn into weather pit when water collects in a depression on granitic surfaces. A possible explanation for weathering is that alternate wetting and drying along the pools that collect in the pans. Darker granitic rocks are high in biotite and weather quicker than the lighter rocks. The foothills are located at the west edge of the park and eastern summit area. They are remains of ancient rocks and sediments. Evolution of the landscape is a big part of the geology just like the rocks themself. As the earth became cooler, the sierra nevada mountains rose high enough for creating glaciers and mountain icefields. The majority of Yosemite is made of plutonic, igneous rock. The plutonic rocks were formed by intrusions of magma into older rocks. These are as old as 130 million years. Forms of plutonic rocks in Yosemite are granite, granodiorite, tonalite, quartz monorite, and quartz monzodiorite. Metamorphic rocks have been changed by pressure that can result in being buried in earth. There are 2 belts of metamorphic rocks, one on each side of the batholith of plutonic
