tektieten

Tektites are natural glass objects formed from terrestrial debris ejected during meteorite impacts. They are typically black, green, or dark brown, and their composition is primarily silica. The name "tektite" is derived from the Greek word "tektos," meaning melted. These glassy projectiles are found in specific geographic regions known as strewn fields, which correspond to the impact sites of meteorites. The heat generated by the impact melts terrestrial rocks and soil, which are then propelled into the atmosphere and cool rapidly as they fall back to Earth, forming the characteristic tektite shape. Tektite shapes vary widely, including spheres, discs, dumbbells, and teardrops, depending on their aerodynamic behavior during flight. Their origin as impactites makes them valuable for studying the effects of extraterrestrial impacts on Earth's geology and atmosphere. Tektites have also been found in archaeological contexts, where they were sometimes used as tools or ornaments by early humans. Their presence on Earth is a testament to the dynamic history of our planet and its interactions with space.
