2024 Flashcards
Conditions for life on Earth- features of Earth that sustain life
Mass, distance from the sun, axis of rotation, speed of rotation and magnetic field
Conditions for life on Earth- early conditions that sustain life
Presence of liquid of water, temp range, atmospheric gases and solar insolation
Conservation- importance of conserving species
Resources, new food species, eradication of pests, biomimetics, medicines, physiological research, genetic resources and ecosystem services
Conservation- human activities threatening wildlife
Direct exploitation, eradication of predators/competitors, abiotic/biotic changes, introduced species and habitat destruction
Conservation- legal protection and categorising species
IUCN, red list, recategorizing, flagship species, keystone species, trade controls and organisations
Conservation- habitat protection
Protected areas, agri-enviro schemes, unintentional/intentional creation
Conservation- habitat design
Abiotic and biotic conditions
Conservation- selected habitats (features, importance, threats and control)
Temperate broadleaf woodland, tropical rainforest, tropical coral reefs, deep water coral reefs, oceanic islands and mangroves
Life processes in the biosphere- succession
Any detailed ecological succession- hydro, psammo or litho
Atmosphere- how the atmosphere supports life
Gases for natural processes, absorption of EM, delaying IR escape, heat distribution, ocean currents and transport water vapour
Atmosphere- consequences of GCC
Ecological changes, changes in climatic processes, cryosphere changes, sea level rise, change sin ocean currents and human societal impacts
Atmosphere- data collection
Proxy data, historic, ice core analysis, satellites, monitoring ocean currents and computer models
Hydrosphere- environmental effects of reservoirs
Habitat change, wildlife barriers, river regime downstream, sedimentation and microclimates
Hydrosphere- environmental effects of aquifer exploitation
Changes in surface hydrology, ecological impacts, salt water incursion, subsidence and reduces supplies
Lithosphere- improvements in exploitation
Remote sensing image resolution, portable field equipment, low-grade deposits and polymetallic nodules
Lithosphere- recycling problems
Labour, transportation, lack of public cooperation, identification, energy costs, separation and waste losses
Biogeochemical cycles- processes, impacts and control
Carbon or nitrogen
Soil- methods to reduce soil erosion
Long-term crops, zero-tillage cultivation, contour ploughing, tied ridging, terracing, rows of stones, windbreaks, multicropping, increased organic matter and livestock management
Energy- fossil fuels
Features, environmental impacts and improvements
Energy- nuclear
Features, advantages vs disadvantages, technology
Energy- renewables
Biofuels, solar, wind, tidal, geothermal and HEP
Pollution- pollutants
Pesticides, solid waste disposal, ionising radiation and oil
Pollution-environmental features affecting pollutant
Temperature, light levels, oxygen, pH and pollutant interactions
Agriculture- pesticides
Cultural (crop-rotation, companion crops, predator habitats, biological control, sterile male techniques, pheromone traps, genetic resistance and GM) vs artificial
Agriculture- controlling abiotic and biotic conditions
Temp(greenhouse, disperse cold air with large fan to prevent frost, cloths, shelter), light(artificial), water (irrigation), nutrients(fertiliser), aeration(ploughing, drainage, add OM, low tillage, livestock management), salinity(adding water), pH(lime/powdered sulfur), pest control, pollinators and maintenance of soil biota
Agriculture- environmental impacts
Habitat impacts, introduced species, pollution, changes in hydrological cycle and soil erosion
Agriculture- manipulation of food species
Population control (density and monocultures), control of genetics (asexual reproduction, selective breedings, crossbreeding), GM
