The transporting power of a glacier is equally high. It can carry any material from loose debris to large boulders as big as a house.

Eroded materials from the gound, sides and plucked up materials from the bed rock are all carried away. Some debris is caught up and is carried within the glacial ice. Most of the rock debris drifted by the glacier on its upper surface is known as glacial drift.

The big boulders which are carried away are known as erratics. Glacier transports the material by traction, suspension and floatation. Actually, no material is suspended within the solid mass, but the materials carried within the glacial ice are said to be in suspension. Similarly, no material floats over the glacier; but the drift carried by the glacier are said to be floating on it.
