Area 2: Earth's Resources
Module overview β- What is the atmosphere made of, how does it drive weather and climate, and how do humans pollute it?The atmosphere: its composition and layered structure, its role in weather and climate, the greenhouse effect, and the causes and effects of atmospheric pollution including acid rain and ozone depletion.11 min answer β
- How does the living world provide resources and services, and how can it be used sustainably?The biosphere: biomes and their distribution, biological and biomass resources, the ecosystem services the biosphere provides, and the sustainable management of biological resources.10 min answer β
- How are rocks, minerals and soil formed, and how do humans use the geosphere?The geosphere: the structure of the Earth, the rock cycle and rock types, the formation and properties of soil, weathering and erosion, and the extraction and sustainable use of mineral resources.11 min answer β
- How does water move through the environment, and how is it managed as a resource?The hydrosphere: the water cycle and the distribution of water, water as a resource, the causes and effects of water pollution, and the treatment of water for supply and after use.11 min answer β
Area 1: Living Environment
Module overview β- What is biodiversity, why does it matter, and how is it measured?Biodiversity as genetic, species and ecosystem diversity; how species and genetic diversity are measured; and the ecological and economic importance of biodiversity.10 min answer β
- How do human activities reduce biodiversity, and how can it be protected?Human influences on biodiversity: habitat loss and fragmentation, overexploitation, the impact of invasive non-native species, pollution, and the methods used to conserve and protect biodiversity.10 min answer β
- How do organisms depend on one another and on the flow of energy and nutrients?Interdependence: ecological niche, competition, predation and herbivory, energy flow through food chains and webs, the recycling of nutrients, and ecological succession.11 min answer β
- How do environmental scientists measure the living and non-living parts of an ecosystem?Investigating ecosystems: biotic and abiotic factors, sampling techniques for measuring abundance and distribution, and the use of indicator species to monitor environmental conditions.10 min answer β
Area 3: Sustainability
Module overview β- How are humans changing the climate, and what can be done about it?Anthropogenic climate change: the enhanced greenhouse effect and its causes, the evidence for human-driven warming, the environmental impacts, and the strategies of mitigation and adaptation.11 min answer β
- How can we meet rising energy demand while reducing environmental harm?Energy: the demand for energy, the comparison of fossil fuels, nuclear power and renewable energy sources, and the move towards a sustainable, low-carbon energy supply.11 min answer β
- How can we feed a growing population without degrading the land?Food: the demand for food and food security, the environmental impacts of agriculture including soil degradation, and sustainable approaches to food production.10 min answer β
- What global pressures make sustainable development necessary, and how is human impact measured?Global challenges: human population growth and its environmental pressures, the concept of sustainability and sustainable development, carrying capacity, and the use of the ecological footprint to measure human demand.10 min answer β
- How can society deal with its waste in the most sustainable way?Waste management: types and sources of waste, the waste hierarchy, methods of disposal and their impacts, and the role of reducing, reusing and recycling in a circular economy.10 min answer β
- How can a limited supply of fresh water meet rising demand sustainably?Water: the demand for water and the causes of water scarcity, the uneven supply of fresh water, and sustainable approaches to managing and supplying water.10 min answer β
