Here's a breakdown:

* Sedimentary rocks are formed from the accumulation and cementation of sediments. These sediments can be:

* Clastic sediments: Fragments of pre-existing rocks (like sand, gravel, or clay)

* Chemical sediments: Minerals precipitated from water solutions (like limestone or rock salt)

* Organic sediments: Remains of plants and animals (like coal or some types of limestone)

* How they form:

1. Weathering: Rocks are broken down into smaller pieces by wind, water, ice, or chemical reactions.

2. Erosion: These broken pieces are transported by wind, water, or ice.

3. Deposition: The transported sediments settle out of the water or air, often in layers.

4. Compaction: Over time, the weight of overlying sediments compresses the lower layers, squeezing out water and air.

5. Cementation: Minerals dissolved in groundwater precipitate between the sediment grains, binding them together and forming solid rock.

Examples of sedimentary rocks that settle out of water:

* Sandstone: Formed from sand grains

* Conglomerate: Formed from gravel-sized fragments

* Shale: Formed from clay

* Limestone: Often formed from the skeletons of marine organisms

* Rock salt: Formed from the evaporation of seawater
