Shale, because sand and other coarse sediments compress little.
Lithification processes, collectively referred to as "diagenesis," include: compaction (example: clay to shale), cementation (example: sand to sandstone), and partial recrystallization (example: lime mud to limestone). Note: Pressure by itself does not by compaction lithify sand to sandstone. Sandstone diagenesis is mostly by cementation and also, sometimes, by partial recrystallization and crystal overgrowths. The same is so of gravel that lithifies to conglomerate.
A clump. Unless they have undergone compaction and cementation in a process known as lithification. Then they would be classified as a sedimentary rock, maybe conglomerate, breccia, or sandstone.
Compaction and cementation of sediments are the processes of lithification which form clastic sedimentary rock.
Lithified detritus forms sedimentary rocks known as clastic rocks. These rocks are composed of fragments of pre-existing rocks or minerals, which have been physically weathered and transported before being deposited and compacted into a solid rock. Examples include sandstone, shale, and conglomerate.
Sandstone is a sedimentary rock that forms from the compaction and cementation of sand grains. In the rock cycle, sandstone is formed from the lithification of sedimentary deposits, eroded from existing rock formations and carried by wind or water before settling to form layers of sand. Over time, these layers are buried and compacted to eventually form sandstone.
Lithification is the compaction of materials into a sedimentary rock, such as sandstone.
Sandstone is formed from compaction and cementation of sand sized particles of rock.

a deposit can change laterally, so it might be deposited a conglomerate upstream and further downstream a sandstone, but once it is deposited it cannot be transformed unless it is subject to heat and/or pressure, it will then be a metamorphic rock. If the river is in retrograde then the deposit will grade upwards from a conglomerate to a sandstone
The weathering, erosion, and deposition of the rock rhyolite could result in the compaction and cementation into sedimentary rock of different types: breccia, conglomerate, sandstone, mudstone, or shale. Which type depends on the degree of weathering and the distance from the point of origin of the original rhyolite.

Sedimentary rock is most likely the result of compaction and cementation of particles. This process involves the gradual accumulation, burial, and lithification of sediment to form rock. Examples of sedimentary rocks include sandstone, shale, and limestone.
Yes, sandstone can become shale through a process called lithification, where sediment undergoes compaction and cementation. However, it is more common for sandstone to transform into a different type of rock, such as quartzite, when subjected to higher temperatures and pressures. Shale typically forms from the compaction of finer sediments like silt and clay. Therefore, while there's a geological connection between these sedimentary rocks, sandstone does not directly become shale.
