Glaciers*

A glacier is a large body of ice that moves slowly down a slope or valley or spreads outward on a land surface.

They move like slow rivers.

They move because they are very heavy.

Glaciers are made up of snow that has turned to ice.

The last glaciers in Nova Scotia were 20,000 years ago.

At one time, glaciers covered all the Maritime provinces.

The glaciers were about one kilometre thick.

The glaciers in Nova Scotia have melted and formed lakes and rivers and raised the ocean level.
