Fulgurites (from Latin fulgur 'lightning' and -ite), commonly called "fossilized lightning", are natural tubes, clumps, or masses of sintered, vitrified, or fused soil, sand, rock, organic debris and other sediments that sometimes form when lightning discharges into ground.

2013年7月2日 · When the lightning perfectly strikes the sand, it branches through it like the root system of a tree to make this beautiful anomaly. But that simple fact is key to getting to the root of the viral photo: The lightning creates a tube of glass through the ground, not above it.

2024年3月15日 · Fulgurites are geological features formed when lightning strikes the ground, fusing sand or soil into glassy structures. They are essentially petrified remnants of lightning strikes, capturing the intense energy and heat generated during the event.

2022年6月28日 · According to the Utah Geological Survey, there are two types of fulgurites: those formed when lightning hits sand and those created from rock. Sand fulgurites come from beaches and deserts,...

2013年7月22日 · This is is exactly what happened when a bolt of lightning struck drifting sand near Drigg, in Cumbria. The intense heat fused the sand grains together to form the delicate glassy tube you can see below – a fulgurite. In fact three fulgurites were discovered in 1812, all quite close together.

Fulgurites are rare natural glass formations created when lightning strikes sand, soil, or rock. The intense heat from the lightning rapidly melts the struck material, which then cools and solidifies into a glassy substanc.

2013年10月22日 · The sand around the lightning strike fuses together, and fulgurite is formed. What are fulgurites? The word – based on the Latin world for thunderbolt – refers to a hollow glass tube formed when lightning strikes soil, silica, sand or even rock.

2024年2月7日 · Petrified lightning (fulgurite) is formed when lightning strikes sand and melts it. The sand fuses together and cools in the shape of the path of the lightning. Fulgurites look like hollow, sandy tubes with smooth, glassy insides.

At 50,000 degrees F—hotter than the surface of the sun!—lightning blasts the sand, vaporizing the area where the bolt of electricity shoots through the sand and melting the surrounding sand into dark glass. “Fulgur” is the Latin word for lightning.

2022年10月5日 · Silicon dioxide is not all that can be found in sand, however, and when extra hot lightning hits sand in just the right conditions, a very rare reaction takes place, as the National Park Service explains.
