Flashcards in Glaciers On Maps Deck (6)
How do you spot a Corrie on a map?
Tightly packed contours in a U shape around it
Some corries have a tarn in them
How can you tell the height / steepness of the land on a map?
Height = numbers
steepness = how close contour lines are
How do you spot an Arête on a map?
Really thin hill with tightly packed parallel contour lines on either side
Often have corries or tarns on either side and footpaths on them with names like striding edge
How can you spot a pyramidal peak on a map?
Tightly packed contour lines that curve away from a central high point
Arêtes and corries around it
How do you spot a glacial trough on a map?
Flag valleys with steep sides so there are no contour lines at the bottom of the valley but tightly packed ones on the sides
Look for a wide straight valley in a mountainous area with a river that looks too small to have formed the valley
