All these different sedimentary rocks are formed from the broken remains of other rocks that become joined together.Sep 23, 2023 · Sedimentary rock, rock formed at or near Earth’s surface by the accumulation and lithification of sediment or by the precipitation from solution at normal surface temperatures. Sedimentary rocks are the most common rocks exposed on Earth’s surface but are only a minor constituent of the entire crust.

Clastic Sedimentary Rocks. How Clastic Sedimentary Rocks are Formed: Pre‑existing rock undergoes chemical and mechanical weathering by roots, acid rainwater, gravity, wind, and water. The broken particles are carried through water or air until they settle out in a lower area when the current wasn’t fast enough to carry the particles.

The pebbles in this rock show a high level of rounding which implies a significant distance of transport. The red color is thought to be iron staining, which is nearly ubiquitous on Mars and gives it the name "Red Planet." The "cement" that binds the particles in these rocks could be a sulfate mineral.
