Clastic sedimentary rocks are formed during a process called diagenesis. The process of diagenesis is similar for many sedimentary rock types. Here is the process described specially for the diagenesis of sand into sandstone. Imagine a large deposit of loose sand sediment along a shoreline. Over a great amount of time, the sand is compacted as more and more sand is piled on top. Greater depths increase heat and pressure, which cause the sand to cement together, and become sandstone. Over time, the material above the sandstone will be eroded, as will the sandstone. Sedimentary rocks that have clasts prone to falling off are said to be poorly cemented, while rocks with clasts firmly in place are well cemented. Sort the statements describing the clasts shown. Drag the appropriate items to their respective bins.
