QUIZZES // Glacial erosion environments

Q1. What percentage of the world’s land area would you guess is currently covered by glacial ice?

1%

10%

35%

80%

Q2. At the peak of the last Ice Age, around 20,000 years ago, sea levels were lower than they are today. But how much lower?

1 metre

12 metres

120 metres

210 metres

Q3. Which one of the following is the right term for the removal of weathered bedrock or other material by glacial ice?

Lithography

Basal slip

Striation

Erosion

Q4. Which one of the following landforms has three or more corries?

Arête

Pyramidal peak

Tarn

Glacial trough

Q5. Which of these glacial processes creates striations?

Abrasion

Ablation

Crushing

Plucking

Q6. Which one of the following is a feature of a glacial trough?

V-shaped valley

Glacial flour

Hanging valley

Outwash plain

Q7. Which one of these features is characteristic of a rôche moutonée but not a depositional crag and tail?

Made of solid rock

Formed by ice moving over an obstacle

One steep side and one side that is more gently sloping

Shows the direction of ice movement

Q8. Which of these types of glacial erosion creates the jagged, fractured end (down-glacier) of a rôche moutonée?

Plucking

Abrasion

Hydraulic action

Chemical erosion by meltwater under the glacier

Q9. Rôches moutonées show the direction of ice movement. How do they do this?

The ice flowed up the jagged lee side and over the gentler slope of the smooth stoss side

The ice flowed up the gentler slope of the smooth stoss side and over the jagged lee side

It isn’t possible to tell from one rôche moutonnée but you can orient glacier direction from a field of rôches moutonées

Glacial flow is at right angles to the stoss slope of the rôche moutonée

Q10. Which of these are wedge-shaped marks due to localised stress concentrations, as rock fragments carried by the glacial bed lodge against protuberances on the bedrock?

Striations

Chattermarks

Kame

Sichelwannen

Q11. In which one of the following environments would you expect to see the highest rates of erosion, other factors being equal?

A warm-based, fast-flowing glacier situated on an unconsolidated bed

A warm-based, fast-flowing glacier situated on rigid bedrock

A cold-based, slow-moving glacier situated on an unconsolidated bed

A cold-based, slow-moving glacier situated on rigid bedrock
