Resource management - human Flashcards
define resources
any feature or part of the environment that can be useful to people
define biotic
obtained from the biosphere and is able to reproduce
define abiotic
obtained from the lithosphere, atmosphere and hydrosphere e.g. minerals, soil, sunlight
define renewable
resources that are potentially inexhaustible and can be naturally replenished
define non renewable
substances that cannot be remade
give examples of renewable abiotic resources
water sunlight wind HEP wave
give examples of non renewable abiotic resources
oil
coal
uranium
gas
give examples of non renewable biotic resources
biogas
dung
soil
fish
how do people use natural resources?
energy
food / farming
fresh water
how is exploitation changing environments?
deforestation
increase in soil erosion
water pollution
critical animal populations- e.g. overfishing in the North Sea
describe how people exploiting environments for food can cause deforestation?
palm oil is being exploited in Cameroon, Africa for products like makeup and biscuits
leads to deforestation, increases soil erosion
what is the link between water supply and population distribution in the UK?
In the South and East the demand for water is greater than supply while in the North and West the supply is greater than demand so there is less water stress than in the south and east.
what is the link between the relief of the Land and Farming in the UK?
flatter relief in the South and East - arable farming
steeper relief in North and West - pastoral farming (sheep)
advantages of coal
supplies should last another 250 years
easy to convert to energy
cheap to mine
disadvantages of coal
burning coal releases harmful gases into the atmosphere
acid rain is produced when coal is burnt
waste heaps are left close to coal mines
