The impact of a meteor causes:
- Material to be ( ejected, destroyed ) and ( quartz, muscovite ) grains to be violently shocked.
- Rock ( strata, beds, sequences ) to be tilted.
- Material at depth to be ( brecciated, destroyed, broken up ).
- Ejected material falls back to the surface resulting in an ( inverted, reversed ) sequence of rock.
This is because material closer to the surface is ejected ( first, last ) and falls back to the surface ( earlier, later ).
