1. What is the definition?A layer of unconsolidated, loose, heterogeneous superficial deposits covering solid rock
2. What is the key locations?Earth, Moon, Mars, Mercury, Venus, and some asteroids and moons
3. How does regolith form?It forms mainly when tiny space rocks hit the surface, breaking up the bedrock. The constant impacts, plus heat changes and wind on some planets, keep the layer loose and mixed.
4. Why is regolith important for space exploration?Regolith keeps a record of a planet’s past, like its history of impacts and weather. It can also hurt equipment and astronauts, but it can be used to make building materials and rocket fuel.

Unconsolidated: Not firmly packed or joined together; loose and easily disturbed.
Heterogeneous: Composed of diverse or different elements or constituents.
Impact Gardening: The process by which meteorite impacts break down and mix surface materials over time.
In-Situ Resource Utilization (ISRU): The practice of using local resources found on a celestial body for exploration and settlement.
