Resource management general Flashcards
(15 cards)
1
Q
4 types of natural resources?
A
- biotic - living things
- abiotic - non living things
- renewable - resources that can be replenished in short timesacle
- non-renwewable - resources that cant be replenished quickly
2
Q
Resource extraction impacts on water and air quality?
A
- fossil fuels release GHG’s into atmosphere - theyre burned
- fishing - oil and petrol can spill from fishing vessels into sea - causing water polltuion
- farming - artificial fertilisers and pesticides applied to crops - can harm or kill organisms
- deforestation - trees remove CO2 from atmosphere - burning vegetaton releases CO2 - global warming
- water - lots of energy needed to transfer water over long distacnes - may require burning fossil fuels
3
Q
Resource extraction impacts on biodiversity?
A
- overfishing - damage ecoysystems and food chains
- farming - removing hedgerows reduces biodiversitty in plants and animals that live in them
- deforestation - loss of habitat and species may go extinct
- water - dams act as barrier to species movements
4
Q
Resourse extraction impacts on soil erosion?
A
- heavy machinery in plant and harvesting can cause soil erosion
- deforestation - removing trees exposes soil - makse easier for water or wind to erode
5
Q
What resources are found in the UK?
A
- soil and africulture - arable farming, cattle farming etc - depends on soil type and and fertility/climate
- forestry
- fossil fuels - Uk has reserves of coal, oil and gas
- water
- rocks and minerals
6
Q
Soil and agriculture?
A
- sheep farming occurs in upland areas e.g. scottish highlands - sheep can cope with harsh climate and terrain
- cattle farming found where climate is warm/wet - lots of grass for cows to east e.g. southwest england
- arable farming mostly east - land flast and soils fertile
7
Q
Fossil fuels?
A
- distribution depends on geology of area
- most onshore oil extracted from south coast and east midlands
- large offshore oil and gas reserves in north sea
8
Q
Forestry?
A
- main coniferous forest plantations in scotland + northern england
- generally found in upland areas where soil too poor for agriculture
9
Q
Water?
A
north and west of UK generally have largest supply of water due to higher rainfall
10
Q
Rocks and minerals?
A
- limestone found in west, central and northern england
- granite found in small pockets across scotland - northwest and southwest england
- slate located in southern scotland and northeast wales
11
Q
Why is energy consumption cloesly linked to development?
A
- developed countries consume lots of energy because people can afford to
- most people have access to electricity, heating, and devices like cars
- less developing countries less able to afford it
- increased industrial activities require large amounts of energy
12
Q
Why do some countries rely on traditional fuel sources?
A
- energy networks poorly connected - people rely on biomass like wood for energy
- little development, so countries cant afford to exploit their energy reserves
13
Q
What does water consumption depend on?
A
- climate - countries with low rainfall may not have much water available
- development - more wealthy people can afford flushing toilets/showers/dishwashers - increases water use - wealthy countries able to invest in schemes to increase water supply if water availability is low
- industrial activities - farming, mining, industry use lots of water - activities very water intensive
14
Q
What is food production influenced by?
A
- climate - too hot or too cold or too dry - food wont grow
- level of development - use of mechanised farm equipmetn can make processes more efficient - genetic engineering can increase plant yields
15
Q
What is food consumpton influenced by?
A
- developed areas can afford to eat a lot - afford to import variety of foods - people on high income can afford to buy lots
- people cant afford as much and less food available in less developed countries
