Quartz is highly resistant to weathering during transportation via streams and rivers.
It is usually quartz
Microcrystalline quartz is created when silica-rich oozes deposited on the seafloor undergo recrystallization over time due to pressure and heat. This process results in the formation of small crystals within the sediment, giving rise to the microcrystalline structure of the quartz.
Quartz is formed through a geological process involving the crystallization of silica (silicon dioxide) from molten magma or through the precipitation of minerals from aqueous solutions. Over time, silica-rich solutions fill cavities in rocks, and as the solution cools or evaporates, quartz crystals begin to form. These crystals grow in size through repeated cycles of crystallization, resulting in the clear, hard mineral known as quartz. Additionally, quartz can form in sedimentary environments through the accumulation and compaction of silica-rich sediments.

Longshore drift.
Depends on the location of the beach, so yes.
Sand is SiO2 and that is also quartz. So you will find sand on the beach.

Quartz consists of silicon and oxygen (2 times as many oxygen atoms than silicon atoms).
Chert is formed through the accumulation of silica-rich sediments, such as microcrystalline quartz, in marine environments. The key processes involved in its formation include the deposition of silica from organisms like diatoms and sponges, as well as the chemical precipitation of silica from seawater. Over time, these processes lead to the compacting and hardening of the silica-rich sediments into chert rock.
