Mass Movement and Glaciers

Front

What is the primary difference between continental glaciers and valley glaciers?

Back

Continental glaciers cover large areas of land, while valley glaciers are narrow and form in mountain valleys.

Front

What is a kettle in glacial geography?

Back

A kettle is a landform created when a glacier melts, leaving behind depressions that fill with water.

Front

Define erosion in the context of geology.

Back

Erosion is the movement of weathered rock and soil from one place to another.

Front

What is plucking in glacial erosion?

Back

Plucking is when glaciers pick up rocks and large boulders and drag them across the land.

Front

What type of glacier covers large areas of land and moves outward from a central location?

Back

A continental glacier.

Front

What are the two main types of glaciers?

Back

Continental glaciers and valley glaciers.

Front

How do glaciers contribute to landscape formation?

Back

Glaciers shape the landscape through processes like erosion, deposition, and the creation of landforms.

Front

What is the process of glacial deposition?

Back

Glacial deposition occurs when glaciers lose energy and drop the sediment they have carried.

Front

What is a moraine?

Back

A moraine is an accumulation of debris (till) deposited by a glacier.

Front

What is the significance of glacial till?

Back

Glacial till is unsorted sediment deposited directly by glacial ice, important for understanding past glacial movements.
