What is the 1970s metal rock band Quartz?
over the period of more than thousand years, various corroding agents like wind and water..flow past the quartz cluster...slowly slowly corroding it into fine particles like the sand... Once in the form of minute particles..it can easily be carried away by wind/ water to the oceans hope I helped :)
Water is a very powerful force. It can carve great canyons. The repeated exposure of water across an object can reduce it to very small, finite particles. This is how beach sand is created - the constant erosion of rocks creates very fine pieces of stone.
Sand grains on the beach started out as a solid rock. Going way back, all rocks were initially volcanic, so we'll start there for simplicity. When you first start weathering rock you end up with smaller chunks of that rock. At the base of a cliff, you just see smaller pieces of the rock that makes up the cliff - it's not much different, just smaller. Water can then pick up these smaller chunks and move them downhill over time. The longer the chunks are bounced around by the water, the smaller they tend to get. Volcanic rocks are made out of a variety of minerals, so over time, those rock chunks break apart into individual minerals. The reason why beaches are mostly quartz sand is because, of the minerals, quartz is the most stable at Earth's surface. Many minerals in rocks break down and turn into clay (a variety of chemical processes can do this). Quartz is strong and chemically stable, so it tends to survive even multiple cycles of weathering, erosion, and rock formation. Rivers run downhill, and eventually the water gets to the ocean. Some of the sediment picked up by rivers in the mountains will also make it to beach and supply the beach with sand. The composition and size of the sand on the beach will depend on the rocks the river flowed over!
