1. Weathering: Rocks are broken down into smaller pieces (sediments) by wind, water, ice, or even living organisms.
2. Erosion: These sediments are transported by wind, water, or ice to a new location.
3. Deposition: The sediments settle and accumulate in layers.
4. Compaction: Over time, the weight of the overlying layers presses the sediments together, squeezing out water and air.
5. Cementation: Minerals dissolved in the water between the sediments crystallize, acting like glue to bind the sediments together.
This process creates a wide variety of sedimentary rocks, including:
* Sandstone: Formed from sand grains
* Conglomerate: Formed from larger pebbles and gravel
* Shale: Formed from very fine clay particles
* Limestone: Formed from the shells and skeletons of marine organisms
* Coal: Formed from the remains of plants
So, the next time you see a rock, think about its journey! It might have once been part of a much larger rock that was broken down and transformed over time.
