Tektites are natural glass formed from the impact of meteorites on the Earth's surface. When a meteorite strikes the Earth at high speeds, the intense heat causes the rock and soil to melt, and the resulting molten material is ejected into the atmosphere, where it cools and solidifies into glass. Tektites can vary in color, typically found in black, green, brown, or transparent shades, and have a smooth, glossy texture. They are often characterized by aerodynamic shapes such as teardrops, spheres, or fragments. Tektites are found in various impact sites around the world, with notable sources including Southeast Asia, Australia, and North America.
