Here's why:
* Sandstone is a clastic sedimentary rock, meaning it's formed from fragments of other rocks.
* Sand is a common component of sandstone, often made of quartz grains.
* Other materials besides sand can contribute to sandstone formation, such as feldspar, mica, and rock fragments.
While sandstone is often formed from sand deposits, it's important to remember that:
* Not all sandstone is made solely from sand. It can include other materials.
* Not all sand deposits form sandstone. The sand needs to be compacted and cemented together through geological processes.
