AQA GCSE Geography (8035) — Living with the physical environment
Did you know the UK's famously variable weather is caused by its location at the meeting point of five different air masses? Depending on which air mass is dominant, the UK experiences various types of extreme weather.
The AQA specification focuses on five main categories of UK weather hazards. You must be able to outline these using specific, formal terminology:
A river naturally overflows its banks occasionally, but what happens when two months of record rainfall hit an unmaintained river system? This is exactly what caused the devastating Somerset Levels floods between December 2013 and February 2014.
The Somerset Levels are low-lying wetlands and a natural floodplain for the Rivers Tone and Parrett. The floods were caused by a combination of physical and human factors.
The impacts of this extreme event were severe across social, economic, and environmental categories. Over 600 houses flooded, leaving villages like Moorland and Muchelney completely cut off and forcing residents into temporary accommodation. Economically, over 14,000 hectares of farmland were underwater for weeks, and total damages exceeded £10 million. Environmentally, the floodwaters became contaminated with sewage and agricultural chemicals, leaving behind deoxygenated water that threatened local ecosystems.
During a severe flood, authorities have to balance saving lives today with preventing another disaster tomorrow. Management strategies are divided into emergency immediate responses and sustainable long-term responses/mitigation.
Immediate responses focused on evacuation and safety. The Environment Agency issued severe flood warnings and the UK Army deployed to distribute sandbags and evacuate 600 homes. High-capacity pumps were imported from the Netherlands to drain 1.5 million tonnes of water per day, while the local FLAG community group used social media to coordinate volunteer rescue efforts.
Long-term responses aimed to reduce future risk. Stagnant water was physically reoxygenated to protect ecosystems. Authorities launched a £100 million Somerset Levels & Moors Flood Action Plan over 20 years. This included dredging 8km of the Rivers Tone and Parrett and physically raising major roads like the A361. Significant hard engineering was also installed, including permanent pumping stations and a Tidal Barrage at Bridgwater.
Every time a new summer temperature record makes the news, it raises the question: is our weather actually changing, or is this normal variation? Evaluating this requires analyzing long-term meteorological records to spot trends in both frequency and intensity.
There is strong evidence that temperatures and rainfall are becoming more extreme. The UK's average temperature has risen by ~1°C since 1980, and the 10 warmest years on record have all occurred since 2002. We are also experiencing more tropical nights. Rainfall shows a similar trend, with an increase in days exceeding 50mm of rain, and 6 of the 10 wettest years occurring since 1998.
However, a balanced evaluation must acknowledge areas where evidence is weaker. Despite the warming trend, the UK still experiences isolated extreme cold events, such as the 2010 "Big Freeze". Furthermore, there is currently no strong evidence of a long-term increase in maximum wind speeds, with annual mean wind speeds showing a slight downward trend since 1969. Ultimately, while wind trends lack clear evidence, the data strongly supports that temperature and rainfall extremes are increasing, linked to broader climate change.
Students often confuse the human cause of the Somerset Levels floods ("lack of dredging") with the long-term management response ("reintroducing dredging"). Keep these distinct in your exam answers!
In 6-mark or 9-mark "Analyse" questions on extreme weather, examiners expect you to name specific local details. Using figures like "£10 million in damages" or places like "Muchelney" secures top AO1 Knowledge marks.
Never use vague phrases like "bad weather" or "it's getting hotter". Always use formal categories (e.g., "prolonged rainfall") and back up points with specific data, such as the 2022 record of 40.3°C at Coningsby.
When evaluating evidence for extreme weather, remember to provide a balanced argument. Discussing the lack of a clear upward trend in wind speeds is an excellent way to show evaluation skills.
Extreme weather
Weather that is significantly different from the average or usual weather pattern for a particular area.
Depressions
Low-pressure systems bringing unstable, wet, and windy weather.
Anticyclones
High-pressure systems bringing stable, dry weather, which can mean clear and hot conditions in summer or cold and frosty weather in winter.
Drought
An extended period of low or absent rainfall, formally defined in the UK as 15 consecutive days with less than 0.2 mm of rain on any one day.
Thunder days
A calendar day on which thunder is heard at a specific observation station.
Floodplain
The flat land adjacent to a river, naturally subject to flooding when the river overflows.
Dredging
The removal of sediment and debris from a riverbed to increase its volume capacity.
Surface runoff
Water from rain that flows over the land's surface rather than soaking into the ground.
Immediate responses
Emergency actions taken during or immediately after an event to save lives and protect property.
Long-term responses/mitigation
Sustainable strategies implemented months or years later to reduce future risk and impact.
Flood Action Plan
A coordinated multi-agency strategy managing flood risk through hard and soft engineering.
Hard engineering
Man-made structures built to control natural processes, such as tidal barrages and pumping stations.
Frequency
How often an extreme weather event occurs over a specific timeframe.
Intensity
The strength or magnitude of a weather event, such as rainfall volume per hour.
Tropical nights
A night where the minimum temperature does not fall below 20°C.
