Which of the following processes does NOT contribute to the formation of sedimentary rocks?

The process that does not contribute to the formation of sedimentary rocks is the cooling of magma. Sedimentary rocks are primarily formed through processes that involve the accumulation and consolidation of sediments over time. These processes include weathering of existing rocks, which breaks down rocks into smaller particles; compaction, where accumulated sediments are pressed together under their own weight; and cementation, in which minerals precipitate from water and bind the sediment particles together.

In contrast, the cooling of magma is a process associated with igneous rock formation. When magma cools and solidifies either below the Earth's surface (intrusive igneous rocks) or after being expelled onto the surface (extrusive igneous rocks), it forms solid rock, but this does not involve the processes unique to sedimentary rock formation. Therefore, the cooling of magma is not relevant in the context of sedimentary rock development.
