1. The lunar surface is covered with a layer of fine, dust-like material called regolith.
2. Craters on the Moon are primarily formed by asteroid impacts and volcanic activity.
3. The Moon lacks an atmosphere, leading to extreme temperature variations between day and night.
4. Mare regions are vast plains of basaltic lava that appear darker than the surrounding highlands.
5. The lunar surface is continually bombarded by micrometeorites, which contribute to its erosion over time.
