AQA Geography Paper One Revision

General Instructions

• The AQA Geography exam has options and case studies; focus on what you've studied in class.
• Check the pinned comment for relevant sections to study.
• Use resources like revision guides, checklists, and practice papers available on the website.

Natural Hazards

Definition

• Natural event with social impact (damage/loss of life).
• Types: tectonic (volcanoes, tsunamis, earthquakes), biological (forest fires), geomorphological (flooding, landslides), atmospheric (hurricanes).

Living Near Hazards

• Reasons: personal preferences, faith in defenses, economic factors, lack of awareness.

Human Activity and Climate Change

• Human activities, like CO2 emissions, increase climate change risks (e.g., extreme weather).

Tectonic Plates

Earth Structure

• Crust: thin surface layer.
• Mantle: thick layer of magma.
• Core: hot center creating convection currents.

Plate Movements

• Constructive: plates moving apart.
• Destructive: plates colliding.
• Conservative: plates sliding past.

Types of Plates

• Oceanic: thin, dense.
• Continental: thick, less dense.

Case Studies

• Chile 2010 & Italy 2009 Earthquakes: Comparison of effects and responses.
• Nepal 2015 Earthquake: High casualty and aid response.

Weather and Climate

Global Atmospheric Circulation

• Affects weather patterns (rainy, hot, cold areas).
• Tropical storms: hurricanes, cyclones, typhoons based on origin.

Tropical Storm Features

• Requirements: high sea temperature, depth, low altitude.
• Formation: Rising air, Coriolis effect, eye of the storm.

Impact of Climate Change

• Increased storm severity, flooding, uncertainty.

Ecosystems and Biomes

Structure and Importance

• Components: producers, consumers, decomposers.
• Nutrient cycling and food webs.

Types of Biomes

• Rainforests: high biodiversity, medicine source.
• Deserts: harsh climate, adaptations needed.
• Tundra and Polar: extreme cold, adaptations critical.

Human Impact on the Environment

Deforestation and Management

• Reasons: agriculture, logging, mining.
• Consequences: loss of biodiversity, climate impact.
• Strategies: conservation, sustainable practices.

Physical Landscapes in the UK

Coasts

• Erosion processes: hydraulic power, abrasion, attrition.
• Landforms: headlands, bays, caves, stacks.
• Management: hard (groynes, sea walls) vs. soft engineering (beach nourishment).

Rivers

• Processes: erosion, transportation, deposition.
• Landforms: waterfalls, meanders, floodplains.
• Management: hard (dams, embankments) vs. soft engineering (flood warnings).

Glacial Landscapes

• Erosion processes: plucking, abrasion, freeze-thaw.
• Landforms: corries, arêtes, pyramidal peaks.
• Opportunities: tourism, agriculture, forestry.

Case Studies

• Lake District and Isle of Arran: Tourism impact and management strategies.

Conclusion

• Continuous learning and adaptation are key in geography.
• Utilize breaks for efficient revision and maintain a healthy study routine.
