relationship between pop + env
Flashcards do conjunto (29)
- 1features of a physical environment i.e. climate, geology etc will determine what?nature of soils, drainage, water supply etc.
- 2both of the previous aspects will in turn affect food prod, energy supplies, settlement patters + human health which contributes to what???pop size, distribution and success at developing resources it has at its disposal
- 3pop growth also has an impact on the natural physical env - the degree and nature of impact depends on what ?- the level of resource consumption
-standard of living
- mitigation measures put in place to reduce an neg impacts - 4give some examples of neg impacts pop growth can have on the env- climate change - floods/ droughts
- pollution of water / land / atmosphere
- ozone depletion
- depletion of finite natural resources
- damage to wildlife and their habitats - 5what is climatethe weather conditions prevailing in an area in general or over a long period.
- 6Rainfall, temp, wind velocity and levels of solar insolation all determine what?- food productivity
- the type of farming system adopted
- the selected species for cultivation - 7for example, many crops need temps of what to grow ?5 degrees
- 8high concentrations of pop are determined by what?- adequate rainfall
- temps that are suitable for crops + rearing livestock
- sufficient sunlight for photosynthesis - 9characteristics of climate can also drive the level and nature of what?disease
- 10give an example of a tropical climate driven diseasemalaria, yellow fever and ebola
- 11these diseases will directly affect what?death rates and life expectancy in the human pop
- 12what is an aspect of the environment which is giving greatest concern to the human pop of the 21st century ?climate change (due to global warming)
- 13what is the most important feature of soil?fertility
- 14what does fertility depend on ?soil structure, texture, acidity, organic matter and nutrients
- 15what will these things above determine ?agricultural output + farming system employed
- 16fertility can be maintained with what?artificial chemical fertilisers
- 17in areas of high pop density why might using chemical fertilisers have unsuitable outcomes ?as can contribute to things like water pollution, eutrophication and increased greenhouse gas emissions
- 18areas with fertile soils are often associated with what type of areas?densely populated areas
- 19some rich volcanic soils or alluvial soils are prone to hazards (floods/volcanic eruptions) which may do what?negatively affect the population
- 20people need access to water to survive - what is water important for ?human hydration, irrigation to maintain food prod, hygiene and sanitation and industrial processes
- 21water supply is important in determining population distribution - where is this well illustrated?in Egypt, 95% of the pop live within 12 miles of the River Nile
- 22concentrations of other resources such as fossil fuels or other valued minerals has given rise to what??industrialisation and densely populated conurbations
- 23define population densitythe average no. of people living in specified area, usually expressed as the no. of ppl per km2
- 24define population distributionthe pattern of where ppl live.
- 25development surges have resulted from some trigger to progresses, give an examplethe industrial revolution (europe)
- 26these development surges have sparked technological developments which have enabled specific areas to do what?support a larger human pop
- 27developments have also allowed the increase in ability of the human pop to control many what?infectious diseases
- 28the control of infectious diseases has been one of the main reasons for what ?a rapid rise in world pop
- 29rapid growth in pop and the process of development have had a largely negative impact on the environment, the impact of individuals will depend on what?- where they live on the planet
- individual lifestyles
- resources and services available to them
