Weathering
The first step is weathering.
Yes, compaction is a step in the formation of sedimentary rocks within the rock cycle. It occurs when layers of sediment are gradually buried by additional sediment, resulting in the compression and consolidation of the sediments. Over time, this process leads to the formation of sedimentary rocks.
The statement that igneous rock must become sedimentary rock is incorrect because rock formation is a dynamic and cyclical process. Igneous rocks can transform into metamorphic rocks through heat and pressure without becoming sedimentary first. Additionally, they can also be recycled back into magma, leading to the formation of new igneous rocks. Thus, while igneous rocks can become sedimentary through weathering and erosion, it is not a necessary step in the rock cycle.
The first step in the rock cycle that turns metamorphic and igneous rocks into sedimentary rocks is weathering. Weathering breaks down rocks into smaller pieces through physical or chemical processes. These smaller rock fragments are then transported and deposited as sediment, eventually forming sedimentary rocks through compaction and cementation.
Detrital sedimentary rocks are made from weathered rocks.
It's when parts of both igneous and metamorphic rocks are crushed together and then they form sedimentary rocks.

Sedimentary rocks are formed by a four step process called Lithification (1. Erosion, 2. Deposition, 3. Cementation, 4. Compaction). Metamorphic rocks are formed by heat, time, and pressure.

Subduction and high pressure.
The first step in making sedimentary rock is the deposition of sediments. This occurs when particles like sand, silt, and clay settle and accumulate in layers, usually in areas such as riverbeds, lakes, or ocean floors. Over time, these sediments are compacted and cemented together to form sedimentary rock.
Water chemically and mechanically weathers sedimentary rocks. It also weathers and erodes all rock types, transporting and depositing the sediments, a step in the formation of sedimentary rock.
