Sedimentary rocks are formed from weathered bits of rocks (sediments). These sediments are deposited into layers. The weight of overlying layers compact the levels of sediment down below, and drinking water flowing in the levels deposits minerals that cement the grains alongside one another.

This is called Make contact with metamorphism. Metamorphic rocks that kind in this manner are never foliated.
Minerals are solids that manifest In a natural way and have a characteristic crystal form. Very hot water deep inside of Earth flows by way of cracks, wherever it can dissolve distinctive substances. When incredibly hot drinking water flows towards the area, it cools and types crystals.
