These outer layers take time to form, and you can see a significant difference in the color of different interior and exterior layers of a quartz crystal found inside a rock. Limestone is a sedimentary rock, which means it was formed from small particles of rock or stone that have been compacted by pressure. Sedimentary rock is important because it often contains fossils and gives clues about what type of rock was on the Earth long ago.

Limestone is a sedimentary rock made almost entirely of fossils.

May 28, 2022 · Tagged: Formed, Sandstone. Sandstone is made of sand grains (0.05mm to 2mm) that may have been deposited in the sea, by rivers, or in deserts, and later cemented together by minerals precipitated from groundwater. Most sandstones are made up largely of quartz grains, because quartz is a very hard and chemically-resistant mineral.

Shale is a fine-grained sedimentary rock that forms from the compaction of silt and clay-size mineral particles that we commonly call "mud." This composition places shale in a category of sedimentary rocks known as " mudstones ." Shale is distinguished from other mudstones because it is fissile and laminated.
