Log in to GEO and try this 12-question A level quiz to see how much you know about glacial erosion environments.
If you haven't already done it go through the 'Glacial erosion environments' web unit to learn more. Or look at it again to help fill in any gaps in your knowledge about chattermarks, striations, plucking and roches moutonnees.
made of solid rock
formed by ice moving over an obstacle
one steep side and one side that is more gently sloping
shows the direction of ice movement
chemical erosion by meltwater under the glacier
The ice flowed up the jagged lee side and over the gentler slope of the smooth stoss side
The ice flowed up the gentler slope of the smooth stoss side and over the jagged lee side
It isn’t possible to tell from one rôche moutonnée but you can orient glacier direction from a field of rôches moutonées
Glacial flow is at right angles to the stoss slope of the rôche moutonée.

a warm-based, fast-flowing glacier situated on rigid bedrock
a cold-based, slow-moving glacier situated on an unconsolidated bed
