What causes lunar regolith particles to possess extremely sharp, fractured edges?
Answer
Billions of years of impacts without atmospheric erosion
Because the Moon lacks a substantial atmosphere, there is no atmospheric drag or erosion process to round off sharp edges. Particles are instead shaped by billions of years of direct micrometeoroid impacts.
