Glacial moraine consisting of thick clay with angular rocks

Card 7
Front
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.

Card 8
Front
An erosional feature produced when ice moved over a layer of hard rock. The hard rock protected the softer rocks behind it forming an outcrop with a steep side facing the ice flow and a gentle slope on the down stream side.

Card 9
Front
A vertical crack in the glacial ice. It may be formed when a glacier begins to move down a steep slope, when it is forced to make a sharp turn.

Card 10
Front
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.

Card 11
Front
Large blocks or rock which were picked up by a glacier then deposited, sometimes hundreds of miles from their source, when the ice melted.
Back
Card 12
Front
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

These are created where smaller valleys meet the main glaciated valley.

Vast areas of ice which can cover much of a continent
