Introduction
Glacial landscapes in the UK were created during the last Ice Age when large glaciers covered many upland areas. As glaciers moved, they eroded the land and deposited material, producing distinctive features such as corries, arêtes, pyramidal peaks, U-shaped valleys and moraines.
Today, many of these landscapes can be found in areas such as the Lake District, Snowdonia and the Scottish Highlands. They provide important opportunities for tourism, farming and hydroelectric power, but also present challenges for management and conservation.
What is a Glacier?
A glacier is a large mass of ice that moves slowly downhill due to gravity.
Glaciers form when:
- Snow accumulates over many years.
- The snow is compressed into ice.
- The ice becomes thick enough to move.
Glacial Erosion
Glaciers shape the landscape through erosion.
Plucking
Plucking occurs when:
- Meltwater enters cracks in rocks.
- The water freezes and expands.
- Rocks become attached to the ice.
- The glacier pulls the rocks away as it moves.
Abrasion
Abrasion occurs when:
- Rocks carried in the glacier scrape against the valley floor and sides.
- The landscape is worn away and smoothed.
Glacial Landforms Formed by Erosion
Corrie (Cwm)
A corrie is a bowl-shaped hollow found on the side of a mountain.
Formation
- Snow accumulates in a sheltered hollow.
- Snow turns into ice.
- Plucking and abrasion deepen the hollow.
- A steep back wall develops.
- After the glacier melts, a tarn (lake) may form.
Arête
An arête is a narrow ridge between two corries.
Characteristics
- Sharp crest
- Steep sides
- Formed by erosion from both sides
Pyramidal Peak
A pyramidal peak forms when three or more corries erode back towards each other.
Characteristics
- Pointed summit
- Steep sides
- Found in mountainous regions
U-Shaped Valley
Glaciers transform V-shaped river valleys into U-shaped valleys.
Characteristics
- Wide valley floor
- Steep sides
- Straight profile
Glacial Landforms Formed by Deposition
Moraines
Moraines are accumulations of rock and sediment left behind by glaciers.
Types
- Lateral moraine
- Medial moraine
- Terminal moraine
Erratics
Erratics are large rocks that have been transported by glaciers and deposited in different locations.
They are often made of a different rock type from the surrounding area.
Opportunities in Glaciated Areas
Tourism
Popular activities include:
- Hiking
- Climbing
- Mountain biking
- Water sports
- Sightseeing
Benefits
- Creates jobs
- Supports local businesses
- Generates income
Farming
Many glaciated areas are suitable for:
- Sheep farming
- Cattle farming
Quarrying
Rock extracted from glaciated landscapes can be used in construction.
Hydroelectric Power
Steep slopes and high rainfall make glaciated areas suitable for generating renewable energy.
Challenges in Glaciated Areas
Accessibility
- Steep slopes can make transport difficult.
- Many locations are remote.
Harsh Weather
- Snowfall
- Strong winds
- Low temperatures
Environmental Damage
Tourism can cause:
- Footpath erosion
- Litter
- Habitat disturbance
Sustainable Management
Strategies used to protect glaciated environments include:
- Repairing footpaths
- Restricting development
- Visitor education programmes
- Managing traffic
- Protecting wildlife habitats
The aim is to balance conservation with economic activity.

Answers
Q1
A glacier is a large mass of ice that moves slowly downhill under the force of gravity.
Q2
- Plucking
- Abrasion
Q3
A corrie is a bowl-shaped hollow formed by glacial erosion on the side of a mountain.
Q4
- Tourism
- Farming
- Quarrying
- Hydroelectric power
Q5
- Steep valley sides
- Wide, flat valley floor
Q6
- Moraine
- Erratic
Q7
- Difficult accessibility
- Harsh weather
Q8
- Creates employment
- Brings income to local businesses
Q9
Meltwater enters cracks in rocks and freezes. As the water expands, the rock is loosened. The glacier then pulls the rock away as it moves.
Q10
Rocks trapped in the glacier scrape against the valley floor and sides, wearing away the landscape and creating smoother surfaces.
Q11
Snow accumulates in a hollow and gradually turns to ice. The moving ice erodes the hollow through plucking and abrasion, creating a bowl-shaped depression.
Q12
Footpath repair reduces erosion caused by walkers and helps protect vegetation and soils from damage.
Q13
Two corries form on opposite sides of a mountain. Continued erosion causes the corries to grow backwards, leaving a narrow ridge between them called an arête.
Q14
A glacier moves through a former river valley and erodes both the valley floor and sides. This creates a wider valley with steep sides and a flat floor.
Q15
Three or more corries erode backwards towards each other. The remaining rock forms a sharp, pointed summit known as a pyramidal peak.
Q16
Large numbers of visitors can wear away footpaths, damage vegetation and disturb wildlife. Increased traffic and litter can also affect the environment.
Q17 (6 Marks)
Tourism is important because it creates jobs and supports local businesses such as hotels, cafés and outdoor activity centres. It also brings money into rural areas. However, excessive tourism can cause environmental damage, traffic congestion and erosion. Overall, tourism provides significant economic benefits but requires careful management.
Q18 (6 Marks)
Glacial erosion through plucking and abrasion creates landforms such as corries, arêtes, pyramidal peaks and U-shaped valleys. When glaciers melt, they deposit material that forms moraines and erratics. Together, erosion and deposition create the distinctive landscapes seen in many upland areas of the UK.
Q19 (6 Marks)
Example: Lake District
The Lake District is located in north-west England and contains many glacial features including corries, tarns and U-shaped valleys. It attracts millions of tourists each year and provides opportunities for farming, outdoor recreation and local businesses. The area’s scenery makes it one of the UK’s most important tourist destinations.
Q20 (9 Marks)
Sustainable management strategies such as footpath repair, visitor education, zoning and habitat protection help reduce environmental damage while allowing tourism to continue. These methods protect landscapes, wildlife and local environments. However, they can be expensive and require continuous funding and monitoring. Overall, sustainable management is effective because it balances environmental conservation with economic opportunities, but success depends on long-term commitment from local communities, visitors and authorities.
