  • Revise issues like over-abstraction, contamination, and saltwater intrusion.

  • Understand sustainable use and how aquifers are monitored and managed.


Air Pollution / Indicator Species

๐ŸŒฌ๏ธ๐Ÿชฒ

  • Know sources and effects of air pollutants: SOโ‚‚, NOx, particulates.

  • Learn about indicator species (e.g., lichens) and what they tell us about air quality.

  • Understand monitoring methods: passive sampling, bioindicators, and electronic sensors.


Oil Extraction

๐Ÿ›ข๏ธ

  • Revise stages: exploration, drilling, extraction, and transport.

  • Environmental impacts: oil spills (e.g., Deepwater Horizon), habitat damage.

  • Consider mitigation methods: double-hulled tankers, blowout preventers, spill response.


Chi-Squared

๐Ÿ“Š

  • A statistical test used to compare observed vs expected results.

  • Great for categorical data (e.g., number of organisms in different conditions).

  • Remember steps: calculate expected values, apply formula, compare to critical value.


Heavy Metal Pollution

โ˜ฃ๏ธ

  • Sources: industry, mining, waste disposal (e.g., lead, mercury, cadmium).

  • Impacts: bioaccumulation, toxicity to aquatic and terrestrial life.

  • Control: phytoremediation, filtration, legal limits and monitoring.


Energy Efficiency

โšก๐Ÿ 

  • Understand ways to reduce energy waste: insulation, LED lighting, efficient appliances.

  • Know how to calculate efficiency using input and useful output.

  • Environmental benefits: reduced emissions, conservation of finite resources.


Climate Change

๐ŸŒ๐Ÿ”ฅ

  • Know the causes: greenhouse gases, deforestation, agriculture.

  • Understand impacts: extreme weather, ocean acidification, species migration.

  • Solutions: renewable energy, carbon capture, international agreements (e.g., Paris Accord).


The Carbon and Nitrogen Cycles

๐Ÿ”„๐ŸŒฟ

  • Carbon cycle: photosynthesis, respiration, combustion, decomposition.

  • Nitrogen cycle: nitrogen fixation, nitrification, denitrification, assimilation.

  • Human impacts: fossil fuel burning, deforestation (carbon); fertilisers, sewage (nitrogen).

AQA A-Level Environmental Science Paper 2

Biomes

๐ŸŒŽ๐ŸŒฑ

  • Understand the major global biomes: tropical rainforest, tundra, desert, etc.

  • Revise their climatic conditions, biodiversity levels, and productivity.

  • Be able to explain threats (e.g. deforestation, desertification) and conservation strategies.


Oceanic Islands

๐Ÿ๏ธ๐ŸฆŽ

  • These are isolated ecosystems with high endemism and vulnerability.

  • Revise evolutionary processes like adaptive radiation (e.g. Darwinโ€™s finches).

  • Understand threats like invasive species, habitat loss, and climate change.


Biomimetics

๐Ÿฆ‹๐Ÿ”ฌ

  • The use of nature-inspired solutions in technology and design.

  • Examples: sharkskin for swimwear, bird wings for aircraft, spider silk for materials.

  • Understand the link between biodiversity conservation and future biomimetic discoveries.


Pollinators / Pesticides

๐Ÿโš ๏ธ

  • Learn about the role of pollinators in ecosystems and agriculture.

  • Understand pesticide impacts on pollinators (e.g. neonicotinoids).

  • Revise strategies to protect pollinators: habitat corridors, organic farming, regulation.


Fishing

๐ŸŽฃ๐ŸŒŠ

  • Know the difference between sustainable and unsustainable fishing.

  • Revise issues: overfishing, bycatch, habitat destruction (e.g. trawling).

  • Management strategies: quotas, marine protected areas, selective gear.


Measuring Humidity / Transects

๐ŸŒก๏ธ๐ŸŒฟ

  • Humidity measured using hygrometers or wet and dry bulb thermometers.

  • Transects used to study changes in distribution across a gradient (e.g. line and belt transects).

  • Understand when to use which method and how to analyse results.


Indirect Evidence in Ecological Sampling

๐Ÿพ๐ŸŒณ

  • Includes signs like droppings, tracks, nests, calls.

  • Useful for studying elusive species without disturbance.

  • Often combined with camera traps or acoustic monitors.


Spearmanโ€™s Rank

๐Ÿ“ˆ๐Ÿ”ข

  • A statistical test to find correlation between two ranked variables.

  • Perfect for ecological data (e.g. light intensity vs plant height).

  • Know how to calculate it and interpret +1, 0, -1 values.


Comparing Human Activity with Natural Processes

๐Ÿ—๏ธ๐ŸŒช๏ธ

  • Human impacts: deforestation, mining, construction, emissions.

  • Natural processes: erosion, volcanic activity, storms.

  • Be ready to compare scale, speed, and long-term effects.
