what are landforms and landscaped created by erosion called?
corries, arete, pyramidal peaks, strations, truncated spurs, trough, hanging valleys, roche moutonnee, crag and tail
1 of 10
what are corries?
an armchair-shaped, steep-sided, hollow at the head of a glaciated valley, orientated to south
2 of 10
what is a tarn?
when pressure and erosion are lower at front of corrie there is deposition of moraine accumalating water behind it
3 of 10
what is an Arete?
several corries lie close, divide seperating them narrows until reduced to a narrow ridge
4 of 10
what is a pyramidal peak?
when galcier continue to erode away mountain from all side
5 of 10
what are troughs?
develop when glaciers widen and deepen original valley, making it steep-sided with a wide, flat base
6 of 10
what are truncated spurs?
glaciers straighten valley, cutting off spurs and leaving cliffs
7 of 10
what is a hanging valley?
forms where ice in a tributary valley cant erode effectively cause of movement blocked by ice in main valley, remaining as trough hanging above maybe a waterfall
8 of 10
how is roche moutonnee created?
by passing glaciers, upstream and downstream, plucks away lose rocks and leaving behind a jaggered surface
9 of 10
how is crag and tail formed?
hard rock with soft rock eihter side, glacier passes and erodes soft rock causing cracks by plucking, making hard rock protrude overtime, creating gentle slope
