Simple Impact Craters- Relatively small, 1km or less- About size of UW Complex Impact Craters- Up to 100 km- City sized- Has central peaks/ mountains in crater Impact Basins- Up to 1000 km- State Sized- Near side of the moon- Variety of features in crater Secondary Craters- After impact- Formed from shot up large debris from larger impacts Rays (Ejecta)- Sends material outwards in surround area...
