Why is All Sand the Same?

The video explains why sand appears similar worldwide, focusing on quartz as its primary component. Quartz forms from cooling magma, making it durable and resistant to weathering. Over time, quartz sand is transported by rivers to beaches, where it accumulates. The video highlights the chemistry and physics behind sand's formation and distribution, emphasizing the commonality of quartz sand on beaches.
