Front

What are glaciers?

Back

Glaciers are large masses of ice that form from compacted snow and move slowly over land.

Front

True or False: Glaciers are solid so they cannot move.

Back

False. Glaciers are solid but they can move slowly due to gravity.

Front

What causes glaciers to move?

Back

Glaciers move due to the force of gravity and the melting of ice at their base.

Front

What is the main component of glaciers?

Back

The main component of glaciers is ice, which is formed from compacted snow.

Front

What is the difference between a glacier and an iceberg?

Back

A glacier is a large mass of ice on land, while an iceberg is a piece of glacier that has broken off and floats in water.

Front

What is the process of glacier formation called?

Back

The process of glacier formation is called glaciation.

Front

What role do glaciers play in the Earth's ecosystem?

Back

Glaciers store freshwater and influence sea levels, climate, and ecosystems.

Front

What happens to glaciers during warmer temperatures?

Back

During warmer temperatures, glaciers can melt, leading to rising sea levels.

Front

What is a glacier's zone of accumulation?

Back

The zone of accumulation is the area where snow accumulates and turns into ice.

Front

What is a glacier's zone of ablation?

Back

The zone of ablation is the area where ice melts and is lost from the glacier.
