* Organic Biogenic Sedimentary Rocks: These rocks are formed from the accumulation and compaction of the remains of living organisms.

* Coal: Formed from the accumulation of plant matter (mostly trees) in swampy environments. Over time, the plant material is compressed and transformed into coal by heat and pressure.

* Basalt: A volcanic rock formed from the rapid cooling of lava.

* Sandstone: A sedimentary rock formed from the accumulation and cementation of sand grains.

* Conglomerate: A sedimentary rock formed from the accumulation and cementation of rounded gravel-sized fragments.
