Ice freezes to rocks surrounding the glacier. As the glacier moves the rocks are pulled with the ice to which they are attached. This results in the pieces or rock being pulled away from the bed and sides of the valley. (8) 2. Large blocks or rock which were picked up by a glacier then deposited, sometimes hundreds of miles from their source, when the ice melted. (8) 5. The loss of ice from a glacier due to surface melting (Summer Months) (8) 6. Glacial moraine consisting of thick clay with angular rocks (4) Down 2. A long and narrow ridge of sand and glacial debris which is raised above the surrounding land. It was once the bed of a stream that flowed beneath a glacier, and was left behind after the ice melted (5) 3. Elongated oval hills made of till. The long axis is parallel to the flow of the original glacier with the steeper end facing towards to flow of the ice. They are a depositional feature. (8) 7. A lake which forms in the hollow base of a cirque (4) 8. These are created where smaller valleys meet the main glaciated valley. (7, 7) 9. A pyramid shaped peak formed when cirques develop all around a mountain. As the cirques erode backwards and meet each other a very sharp and jagged peak is formed. (9, 4) 10. A steep armchair shaped hollow formed by the erosion of the rock by snow and ice. The rotational movement of the ice within hollows out the base creating a depression. (6)
