Answer :
The type of rock that is formed on the floors of bodies of water as rock particles are compacted and cemented together is **sedimentary rock**. Sedimentary rocks are formed through the accumulation, compaction, and cementation of sediments.
Here's a simple breakdown of how sedimentary rocks are formed:
1. **Weathering**: Rocks on the Earth's surface are broken down into smaller pieces through weathering processes like erosion, wind, water, and ice.
2. **Transportation**: These rock particles are then transported by water, wind, or ice to bodies of water where they settle.
3. **Deposition**: The particles settle and accumulate on the floors of bodies of water over time.
4. **Compaction and Cementation**: The weight of the overlying sediments compacts the lower layers, squeezing out water and air. Minerals dissolved in water precipitate out and act as cementing agents, binding the particles together to form solid rock.
Through this process, sedimentary rocks like sandstone, shale, and limestone are formed. They often contain visible layers or strata that provide clues about the Earth's history and the conditions under which they were formed.
