The video explains the uniformity of sand across the world, primarily composed of quartz, a mineral formed from silicon and oxygen. Quartz's durability is due to its formation in cooling magma, making it resistant to weathering. Over time, quartz sand is transported by rivers to beaches, where it accumulates. While not all beaches are purely quartz, the commonality of quartz in sand is due to its chemical and physical properties.
