Here's how it works:

* Sedimentary rocks form from the accumulation of sediments, like mud, sand, and clay.

* These sediments are transported by wind, water, or ice, and then deposited in layers.

* Over time, the weight of overlying layers compresses the sediments, and dissolved minerals in the water cement them together, forming rock.

Examples of sedimentary rocks include:

* Sandstone: Formed from sand grains

* Mudstone: Formed from fine-grained clay and silt

* Limestone: Formed from the accumulation of shells and other organic matter

* Conglomerate: Formed from larger, rounded pebbles
