Here's a breakdown:
* Sediments: These are loose, solid particles that come from the weathering and erosion of existing rocks, minerals, or even the remains of organisms.
* Compaction: As layers of sediment accumulate, the weight of the overlying material presses down, squeezing out water and air, causing the particles to become more tightly packed together.
* Cementation: Minerals dissolved in groundwater precipitate between the sediment grains, acting like glue to bind them together. These minerals often include calcite, silica, and iron oxides.
Examples of sedimentary rocks include:
* Sandstone: Formed from cemented sand grains.
* Conglomerate: Formed from cemented gravel-sized particles.
* Limestone: Formed primarily from the accumulation of shells and other marine organisms.
* Shale: Formed from compacted clay and silt particles.
* Coal: Formed from the accumulation and compaction of plant matter.
