The sand on our beaches in California primarily originates from the Granites of the Sierra Nevada mountains
What are Granites?
The igneous rock known as granite has light-coloured granules that are large enough to be seen by the eye. It is created when magma beneath the surface of the Earth slowly crystallises.
Quartz and feldspar make up the majority of granite's chemical makeup, with only trace amounts of mica, amphiboles, and other minerals. Granite typically has a red, pink, grey, or white appearance due to its mineral makeup, with black mineral grains visible throughout the rock. The most well-known igneous rock is granite. Granite is the most prevalent igneous rock on Earth's surface, and since it is used to build so many items in daily life, it is widely recognised. These include stair treads, floor tiles, curbing, paving stones, countertops, building veneers, and gravestones. Granite is used everywhere.
