Sedimentary
Sedimentary rocks form as pieces of loose material get pressed or cemented together. The process of forming sedimentary rocks is lithification.
Sedimentary rocks are made of various materials such as mineral fragments, organic matter, or chemical precipitates. These materials accumulate over time in layers and become compacted and cemented together to form rocks like sandstone, shale, or limestone.
Welded tuff is forms when the ash deposited is so hot that it is still partially molten. The still liquid component then cools, fusing the deposit into a single solid mass. Cemented tuff becomes bound together from processes similar to those that form ordinary sedimentary rocks. Grains are bound together under pressure as minerals dissolved in water crystallize.
When sedimentary rocks break down and then are compacted by pressure, the resulting rock will be a metamorphic rock.

If they are deposited, compacted, and cemented together, they form a sedimentary rock.
The process of sediments being compacted and cemented to form sedimentary rocks is called lithification.
It must be exposed, weathered into smaller rock particles, transported by wind, water, ice, or gravity to a place of deposition, covered by additional sediments, compacted, and cemented together by minerals.
Limestones are form by precipitation of rusually under water Sandstones are formed from sendiments that are being eroded and compacted and cemented together. Shale are formed from precipation also but you often see fossil records on them.
Rocks formed from layers of materials that settle and get cemented together are Sedimentary Rocks.
This happens because the rock cycle keeps occuring and every time the rock cycle happens the sedimentary rock comes together better and will eventually be a solid mass of sediment

Sedimentary
Sedimentary rocks form as pieces of loose material get pressed or cemented together. The process of forming sedimentary rocks is lithification.
In order to become a sedimentary rock a rock must be broken down or eroded by weathering. The sediments of the rock then go through the lithification process where they are cemented and compacted together forming a sedimentary rock.
