What are tektites?

Tektites are natural glass formations that are primarily created from the heat and pressure produced during impact events, such as meteorite strikes. The correct answer refers specifically to tiny glass spheres that can be found on celestial bodies like the Moon. These spheres, which are indeed no larger than sand granules, are formed when a meteorite impacts the surface, causing materials to vaporize and then cool quickly, resulting in glassy fragments.

This formation process is significant because it highlights how extraterrestrial impacts contribute to the development of geological features on other planetary bodies. The presence of tektites can provide scientists with valuable information about the impact events that created them and the conditions present on the Moon's surface at that time. Understanding tektites helps researchers piece together the history of celestial impacts and the geological evolution of the Moon and potentially other planetary bodies.
