Sedimentary rock

Sedimentary rocks form from layers of sediment accumulating over time. As debris builds up, the lower layers experience increased pressure, transforming the sediment into rock. Common sedimentary rocks include sandstone and limestone, which are frequently found on the Earth's surface.
