Striations are parallel scratch marks on bedrock caused by the movement of glaciers.

Front

What are erratics?

Back

Erratics are enormous boulders transported and deposited by glaciers, often found far from their source region.

Front

What type of glacier forms in a mountainous area?

Back

Alpine glaciers form in mountainous areas.

Front

What is a continental glacier?

Back

A continental glacier is a massive ice sheet that covers large areas of land, typically found in polar regions.

Moraines are accumulations of debris (rocks and soil) that have been pushed along by a glacier.

Front

What is the process of plucking in glacial movement?

Back

Plucking is the process by which a glacier removes blocks of rock from the ground as it moves.

Front

What is the difference between a valley glacier and a continental glacier?

Back

A valley glacier forms in mountainous areas and flows down valleys, while a continental glacier covers large land areas and is not confined to valleys.

Front

What are fjords?

Back

Fjords are deep, narrow inlets of the sea between high cliffs or steep slopes, often formed by glacial activity.

Front

What is glacial abrasion?

Back

Glacial abrasion is the process of wearing down rock surfaces as a glacier moves over them, often resulting in smooth surfaces.
