Answer:
Cooling
Step-by-step explanation:
Rocks are of different types. One of those types is the Sedimentary rock, which is the type made from sediments of rocks that have once existed. These rocks don't just appear out of nowhere, they gradually develop in a series of processes. The processes involved in the formation of sedimentary rocks are: weathering, eroding, transportation, deposition and cementation.
Weathering, which is the first process, involves breaking down of pre-existing rocks which are then carried by certain physical forces like wind, water etc. This process is called erosion. The washed material is then transported away from the original site, to be deposited in another environment. The deposited material/sediments then undergo a compaction and cementing process where the rock particles glue together to eventually form the sedimentary rock. This process is called Lithification.
Therefore, cooling is not one of the processes that forms sedimentary rocks.
