Landscape image interpretation task View the images in each of these slides. There is a question beneath each image – attempt to answer each one. Note down your answers so that you can review them later or use them as part of a class discussion.

The Alps (Switzerland) Blue Ridge Mountains, South Carolina, USA http://commons.wikimedia.org/wiki/Matterhorn#mediaviewer/File:Valais_mountains.jpg http://commons.wikimedia.org/wiki/File:Blue_Ridge_Mountains_at_Tamassee,_South_Carolina.jpg?uselang=en-gb Ignoring the fact that one of the images has snow and ice in it and the other does not, What differences do you notice in the shapes of the two landscapes?

Grand Teton National Park, Wyoming, USA DEA The sharp edged, angular rocks on this slope are called pieces of ‘scree’ (or ‘talus’). Can you think of what ‘physical weathering’ process has broken up the rock into these pieces? And how does it work?

Blue Glacier, Olympic Range, Washington State, USA http://commons.wikimedia.org/wiki/File:Mount_Olympus_Blue_Glacier_from_Lateral_Moraine_Panorama.jpg?uselang=en-gb Aaron Linville Notice the rocky debris along the sides of this glacier (called ‘lateral moraine’) Viewed close up, the pieces of rock would be jagged and angular as in the previous photo. Where has this rocky debris come from, and how do you think it got to the glacier?

A photo looking underneath a glacier http://www.swisseduc.ch/glaciers/glossary/glacier-sole-en.html J.Alean & M.Hambrey How do you think pieces of rock debris can get picked up by the glacier as it moves over the ground? Hint: there is melting and refreezing of water beneath glaciers.

http://commons. wikimedia. org/wiki/File:Glacial_striations. JPG http://commons.wikimedia.org/wiki/File:Glacial_striations.JPG?uselang=en-gb These scratches (glacial ‘striations’) formed in the past when a glacier was in this valley. Can you describe the process that caused the scratches on this rock outcrop? Hint: glaciers move rocky debris inside and under them as well as along the surface.

One of these valleys was eroded out by a http://commons.wikimedia.org/wiki/File:V-shaped_valley_below_Craig_y_Gath_-_geograph.org.uk_-_811259.jpg?uselang=en-gb Rudi Winter One of these valleys was eroded out by a glacier. Describe the shapes of the two valleys and suggest reasons for the difference. http://commons.wikimedia.org/wiki/File:U-Shaped_valley,_Glen_Clova_-_geograph.org.uk_-_477230.jpg?uselang=en-gb Gwen and James Anderson

Hummocky moraine in north-west Scotland DEA Describe the shape of the piles of rocky debris in the photograph. Why do you think this can be interpreted as the work of glacier ice rather than of running water?

Whistler, British Columbia, Canada DEA What evidence is there in this photo that glaciers extended further down the mountain slopes in the past?

Snowdonia, north Wales http://commons.wikimedia.org/wiki/Snowdonia#mediaviewer/File:Snowdon_massif.jpg What evidence is there in this photo that this area used to have glaciers?
