Glaciers Vocabulary and Landforms

Front

What is an erratic in geology?

Back

An erratic is a rock or boulder that has been transported from its original location by glacial action and is not native to the area where it is found.

Front

Describe a drumlin and its formation.

Back

A drumlin is a teardrop-shaped landform formed by the movement of glacial ice, typically consisting of a streamlined hill of glacial till.

What is the significance of low latitude in relation to temperature?

Back

Low latitude areas receive more direct sunlight throughout the year, resulting in warmer temperatures compared to high latitude areas.

Front

Explain the process of basal slip in glaciers.

Back

Basal slip is the sliding of a glacier over its bed due to the presence of meltwater at the base, which reduces friction.

Front

At what temperature does water freeze in degrees Fahrenheit?

Back

Water freezes at 32 degrees Fahrenheit.

Front

What are the main types of glaciers?

Back

The main types of glaciers are alpine glaciers (found in mountainous regions) and continental glaciers (large ice sheets covering vast areas).

Front

Define glacial till.

Back

Glacial till is unsorted sediment deposited directly by a glacier, consisting of a mixture of clay, silt, sand, gravel, and boulders.

Front

What is a moraine?

Back

A moraine is an accumulation of debris (till) that has been transported and deposited by a glacier, often forming ridges.

Front

How do glaciers erode the landscape?

Back

Glaciers erode the landscape through processes such as plucking and abrasion, which remove rock and sediment as they move.

What is the difference between a glacier and an ice sheet?

Back

A glacier is a smaller body of ice that forms in mountainous areas, while an ice sheet is a massive, continuous layer of ice covering a large area, such as Antarctica.
