Forms from: 1. Coal 2. Sandstone 3. Rock Salt 4. Shale 5. Coquina 6. Chalk 7. Conglomerate PART C Label each statement from #1-5 based on the processes that form a clastic sedimentary rock. #1
should be the first process to occur, while #5 is the last process.
_____ The river eventually deposits the weathered sediment into a lake or ocean. _____ The pressure from all the layers of sediment squeezes and compacts them together. _____ Minerals within the water cement the sediment together, forming sedimentary rock. _____ More and more layers of sediment accumulate at the bottom of the lake or ocean. _____ A river picks up loose sediment (like sand and clay), and weathers the sediment, making the particles smaller as they move down the river.
