Geology Flashcards
1
Q
rock types with a weak lithology
A
clay has a weak lithology - meaning it has little resistance to erosion, weathering and mass movement
2
Q
why are basalt and granite resistant
A
due to dense interlocking crystals
3
Q
structure of porous rocks (chalk)
A
they have tiny air spaces that separate the mineral particles - allows them to absorb and store water
4
