Module 3, DQ 3

Glaciers are solid so they cannot move.

• True

• False

A glacier is a large body of compressed snow. It moves very slowly over hundreds of years. As it moves, it can erode the ground it passes over. The diagram shows 4 different tests. The tests show how ice moves over sand and clay.

A block of ice is added to each of the four trays. In Diagrams A&B, the blocks of ice have formed from water only.

In Diagrams C&D, the blocks of ice have formed with a layer of gravel at the bottom. The blocks of ice are pushed in the direction of the arrows very slowly then left to melt.

Both the plain ice and the gravel ice leave a path in the sand.

• True

• False

Sometimes gravel falls off the ice block and is left behind, embedded in the sand or clay.

The gravel ice leaves scratches in the clay and grooves in the sand.

The plain ice moves more easily on the sand than the clay.

The gravel ice pushes the sand ahead of the block. The sand piles up in front, forming a small hill.
