Edexcel GCSE Geography A (1GA0) — The Physical Environment
Imagine standing on a steep valley side during a heavy rainstorm—would you rather be surrounded by dense forest or bare, grazed rock? The type of land use in a glaciated upland drastically changes how water and soil behave.
Farming (Extensive Pastoral)
Forestry (Coniferous Plantations)
Settlement & Infrastructure
Overall Assessment of Physical Impacts: When assessing which activity causes the most significant physical change, farming has the most widespread impact across glaciated uplands due to extensive land use. However, settlement and infrastructure create the most permanent and intensive physical disruption. While forestry's impact oscillates between protective (when mature) and destructive (when felled), human settlements permanently lock in altered hydrology through impermeable surfaces and entirely disrupt natural physical processes with large-scale reservoirs.
The impact of impermeable surfaces on misfit streams is measured using a hydrograph calculation to find the lag time:
Worked Example:
A severe storm hits a glaciated valley with new road infrastructure. Peak rainfall occurs at 14:00. The river's peak discharge occurs at 15:30. Calculate the lag time and suggest what this indicates.
Step 1: Identify the values.
Step 2: Calculate the difference.
Step 3: Interpret the result.
Every time a visitor buys a coffee or parks a car in a national park, they are changing the local economy and environment.
Advantages (Economic & Social):
Disadvantages (Social & Environmental):
To ensure sustainable development and mitigate environmental degradation, management strategies like 'Fix the Fells' are used. They repair path erosion using techniques like pitching (creating stone stairs) and soil inversion.
Balanced Judgement: While tourism undeniably alters the landscape through visible footpath erosion and landscape scars, the physical damage is relatively superficial and can often be reversed or managed through mitigation strategies like 'Fix the Fells'. Therefore, tourism rarely permanently alters the fundamental physical character of the relict landscape.
The exact physical features that make glaciated uplands beautiful—steep slopes and extreme rainfall—also make them perfect for generating electricity.
Large-Scale Energy (HEP):
Small-Scale Energy (Wind):
Balanced Judgement: Energy developments in glaciated uplands are highly controversial. While the benefits (grid stability, green energy targets) are primarily felt nationally and the costs (visual pollution) locally, the degree to which these developments permanently alter the character of the landscape is profound. Unlike tourism, large-scale energy projects such as HEP dams permanently flood valley floors and bury ancient relict landscapes under massive concrete infrastructure. Therefore, energy development causes the most permanent, irreversible landscape change, shifting the area from an unspoilt wilderness to an industrialised, heavily managed environment.
Students often just list human activities in 'Assess' questions. You must explicitly link the human action (e.g., clearing trees) to the physical process (e.g., reduced interception) and the final landscape consequence (e.g., mass movement).
For 8-mark 'Evaluate' questions on development, examiners expect you to name specific locations (e.g., Windermere or Keswick, not just 'a lake' or 'a town') to access the highest mark bands.
A strong conclusion for 'Evaluate' questions on development is to compare the degree of permanent landscape alteration. Contrast the superficial, manageable impacts of tourism (e.g., footpath erosion) with the profound, irreversible changes caused by large-scale energy infrastructure (e.g., flooding valleys).
When evaluating management strategies, mentioning 'Fix the Fells' or 'Electric Mountain' shows examiners you understand how human-induced landscape change can be actively mitigated.
Extensive pastoral farming
Rearing livestock (usually sheep) at low densities over a large area, typical in environments with poor soil and steep relief.
Overgrazing
When too many animals graze in one area, leading to total vegetation removal and subsequent soil degradation.
Surface runoff
Water that flows over the land surface because soil is saturated or rainfall intensity exceeds infiltration capacity.
Interception
The process by which precipitation is caught and held by vegetation before reaching the ground.
Evapotranspiration
The combined process of water evaporating from the ground and transpiring from plants into the atmosphere.
Mass movement
The downhill movement of weathered material (soil and rock) under the influence of gravity, often accelerated by saturation.
Footpath erosion
The wearing away of the ground surface caused by the mechanical action of thousands of feet, leading to loss of vegetation and soil.
Landscape scar
A visible mark of degradation on a hillside, often caused by deep-cut eroded footpaths that stand out from a distance.
Landscape change
The permanent, visible alteration of an area’s character—shifting a glaciated region from an "unspoilt pastoral wilderness" to an industrial or heavily managed landscape.
Relict landscape
A landscape primarily shaped by past processes (like glaciation) that are no longer active, meaning human activity is now the main driver of physical change.
Honeypot site
A location that attracts large numbers of tourists, leading to intense environmental pressure, traffic congestion, and overcrowding.
Pumped storage
A hydroelectric system where water is pumped from a lower to an upper reservoir during off-peak hours and released through turbines during peak demand.
Multiplier effect
The process where initial tourist spending leads to further rounds of spending in the local economy, amplifying the economic benefit.
Thin, acidic soils
Shallow, nutrient-poor soils common in glaciated uplands due to high rainfall (leaching) and cold temperatures slowing organic decay.
Impermeable bedrock
Solid rock, such as granite, that does not allow water to infiltrate, leading to increased surface runoff.
Relief rainfall
Rainfall that occurs when moist air is forced to rise over steep upland terrain, where it cools, condenses, and precipitates.
Coniferous plantations
Large, managed forests of evergreen trees (like pine or spruce) planted primarily for commercial timber production.
Misfit streams
A small river or stream flowing in a wide, deep U-shaped valley that was originally carved by a much larger glacier.
Eutrophication
The process where a body of water becomes overly enriched with nutrients (e.g., from agricultural fertilisers or animal waste), leading to excessive plant and algal growth and oxygen depletion.
