Tektites are natural glass, generated by a huge meteorite impact.
陨石玻璃是自然形成的玻璃，由巨大陨石撞击产生。
By hitting the ground the kinetic energy from the meteorite was set free in a huge explosion, that vaporised the meteorite and the surrounding earth surface. Jets of rock steam were ejected from the new born crater. The steam jets cooled down in the higher atmosphere and condensed to glass that rained down up to hundreds of kilometres away from the impact.
当陨石撞击地面时，陨石的动能在一场巨大的爆炸中释放，蒸发了陨石及周围地表。新生成的坑口喷出岩石蒸汽柱，这些蒸汽柱在高层大气中冷却并凝结成玻璃，像雨点般落下，范围可达距离撞击点数十至数百公里之遥。
