  • Understand data collection: satellite imaging, ice cores, and temperature records.

Aquifers

πŸ’§

  • Know how aquifers store groundwater in porous rock (e.g., chalk, sandstone).

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

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

Air Pollution / Indicator Species

🌬️πŸͺ²

  • Know sources and effects of air pollutants: SOβ‚‚, 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

πŸ›’οΈ

  • 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

πŸ“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

☣️

  • 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

⚑🏠

  • 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

🌍πŸ”₯

  • 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

πŸ”„πŸŒΏ

  • 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

🌎🌱

  • 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

🏝️🦎

  • These are isolated ecosystems with high endemism and vulnerability.

  • Revise evolutionary processes like adaptive radiation (e.g. Darwin’s finches).

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

Biomimetics

πŸ¦‹πŸ”¬

  • 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

🐝⚠️

  • 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

🎣🌊

  • 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

🌑️🌿

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