Here's why:
* Lightning's Heat: While lightning is incredibly hot, the contact with sand is usually fleeting. It's unlikely to create a significant change in the sand's composition or structure.
* Sand's Composition: Sand is made up of various minerals. The heat of lightning might melt some of the sand's components, but this would likely result in a small, localized area of fused sand, not a distinct rock type.
What might happen:
* Fused sand: The sand could fuse together in small, localized areas where the lightning struck, forming a glassy substance similar to fulgurite. Fulgurite is typically formed when lightning strikes soil or rock, but it's possible to form in sand as well.
* Slight color change: The heat might slightly change the color of the sand in the area where the lightning struck.
In short, while lightning striking sand might cause some localized changes, it wouldn't create a distinct rock type with a specific name.
