Weathering of existing rock is the first step in the formation of most sedimentary rock, providing the sediment which will eventually be eroded, deposited, compacted and cemented together.

sedimentary rock.
Sedimentary Rocks. Sedimentary rocks are created from stratification by the layering of materials on one another which then get compacted and cemented by sedimentation process over long period of time. The whole process of formation of sedimentary rocks from sediment is called Diagnesis. Examples of sedimentary rocks are limestone, chalk, and sandstone.
limestone
It is compacted and cemented by minerals.
sedimentary rock
Clastic or bioclastic sedimentary rock is formed in this manner.
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.
Weathering of existing rock is the first step in the formation of most sedimentary rock, providing the sediment which will eventually be eroded, deposited, compacted and cemented together.
Sedimentary rock is formed from sediments are piled on top of one another, then compacted and cemented into rocks. Sandstone and limestone are examples of sedimentary rocks.
Sedimentary rocks are made by the majority of the crust are covered by a thin veneer of loose sediment, and the rock which is made as layers of this debris get compacted and cemented together.
No. Volcanic rocks are igneous (although not all igneous rocks are volcanic). Sedimentary rocks are made of sediment naturally cemented together. However, volcanic (or extrusive igneous) rocks can be eroded into sediment, which can be cemented, compacted, or otherwise become sedimentary rock such as sandstone or conglomerate. It is then not considered igneous.
Erosion breaks down a metamorphic rock then the particles get deposited and get cemented or compacted together forming a sedimentary rock.
clay
Sediments produced from weathering and erosion are deposited in still environments, compacted by the weight of additional sediments and cemented by minerals that are present in the water that is being squeezed out between sediment particles.
