Freeze thaw: Water gets into cracks in exposed rock, temperatures drop then water freezes and expands, this enlarges the crack, the ice thaws and process repeat until eventually the rock breaks off.
Freeze thaw steepens the wall of a corrie and leaves it jaggy.
Plucking: Ice freezes onto loose rock (from freeze-thaw) on the back wall of glaciers, as glacier moves downhill it pulls the loose rocks with it.
Plucking steepens the walls and leaves them jagged.
Abrasion: Rock at the bottom of the a glacier (from freeze thaw and plucking) are dragged along the base of the hollow as the glacier moves downhill, this scrapes away at the rock.
Abrasion smooths and deepens the base of the corrie.
