Deposition by Moving Ice As a glacier moves, it transports eroded material. These materials are carried on the surface of the ice (supraglacial transport), within the ice (englacial transport) and underneath the glacier (subglacial transport).

Supraglacial: Materials found on the surface of the glacier, along the top or sides. Such material is carried along as the glacier moves. This material has usually fallen down the mountain and landed on the sides or top of the glacier.
Englacial: Any regolith (loose material) trapped within the ice, including material that has fallen down cracks in the ice.
Subglacial: Loose regolith trapped underneath the glacier and dragged along in the bottom of the ice.
1. Name and describe the three ways that glaciers transport materials.
2. Draw and label a diagram showing how glaciers transport eroded material.
