How Diamonds Form and Why They Are So Strong

SciShow Kids

This educational video explores the geological origins and unique properties of diamonds, distinguishing them from ordinary rocks. Hosted by Jessi and her robot friend Squeaks, the video explains that diamonds are actually crystals made of carbon, formed under immense heat and pressure deep within the Earth. It uses accessible analogies, such as building blocks, to demonstrate how atomic arrangements affect material strength. The narrative covers the timeline of diamond formation, noting that most formed billions of years ago—long before dinosaurs existed. It details the specific conditions required for their creation, including depths of around 150 kilometers underground, and explains how violent, deep-source volcanic eruptions brought them closer to the surface where they could cool and eventually be discovered by humans. For educators, this video serves as an excellent resource for Earth Science units covering rocks and minerals, geological processes, and states of matter. It introduces concepts like crystalline structure, the element carbon, and the layers of the Earth in a way that is comprehensible for elementary students. The video also touches on practical applications of diamonds beyond jewelry, such as in industrial cutting tools, linking science to real-world technology.
