3 UK Environmental Challenges (all content until EOY - so not complete) Flashcards
(45 cards)
weather vs climate
day to day meteorological conditions vs meteorological conditions calculated over a 30 year period
UK’s prevailing wind
from the south west (over warm atlantic ocean - moderate temp and high rainfall)
air mass
a large parcel of air in the atmosphere; all parts of it have same temp. and moisture content at ground level
air masses affecting UK (where are each from)
polar maritime
wet cold air - cold showers
arctic maritime
wet, cold air - snow in winter
polar continental
hot air - dry summers
cold air - snow in winter
tropical maritime
warm, moist air - cloud, rain and mild weather
tropical continental
hot dry air - hot weather in summer
north atlantic drift
continentality
land gains/loses heat quicker than the sea
because of:
evaporation (amount of energy required for heat transfer), transparency of material (albedo), sea surface temperatures
how does uk latitude affect climate
uk higher latitude - same amount of heat spread over a wider area = cooler
strong winds
tropical maritime (then maybe polar or artic maritime)
impacts:
transport infrastructure damaged - cant go to work
houses/property damaged - stress - repairs (inconvenience + cost)
events cancelled - eg motorsport
coastal defences damaged 0 pollutants in water (eg oil)
destruction of habitabts - trees uproot
heatwave (L)
tropical continental air mass
impacts:
drinking water supplies down - dehydration (for older people)
chickens/pigs dying and crops failing (farming) - food prices rise - in 2003 it cost £13B to European farming
tourism up (beaches)
low river levels - less living space for aquatic life
heavy snow
AM and PC air masses - heavier towards north of UK and upland areas
Ec:
disrupts transport networks - people cant go to work / do economic activities
disrupts trade - less food products to remote communities (S)
S:
people stuck in cold - medical issues (cant access medication) OR babies/elderly
water pipes freeze - expand - pipes crack - no hot/drinking water - supplies have to be helicoptered in
Env:
problems with power supplies - dd uip - need for gas up - fossils fuels will need to be burned for the sudden increase in dd
more grit needed - salt getting into water supply - minor issue but grit is also bad for cats
modification of environment: farming
modification of environment: commerical fishing
modification of environment: wind farms
Wind energy advantages
Falling relative cost of energy
Produces no greenhouse gases
Infinite supply of energy
Wind energy disadvantages
Affects natural beauty of open countryside
Can cause some noise pollution (older turbines)
Can affect bird migration
An unreliable source of energy/still require other sources
modification of environment: fracking
Fracking advantages
Causes gas costs to decrease
Increasing gas supply improves energy security
Skilled jobs created within the industry
Fewer carbon emissions than coal and oil
Fracking disadvantages
Groundwater could become polluted with chemicals
Shale gas is a non-renewable resource
Can cause minor earthquakes
Gas produces greenhouse gases when burnt
why is water supply an issue? 2 solutions?
most of supply is in north, but most of demand is in south and east (40% energy, 40% domestic, 20% industry, 1% agriculture)
2 solutions:
reservoirs (store water)
water transfer schemes (transfer water from areas of high supply to high demand)
costs of reservoirs
displace locals, bock nutrient flows
costs of water transfer schemes
wildlife movements change, spread of disease
renewable vs non renewable
produced from energy sources that do not run out vs producted from those who do OR become too economically/environmentally expensive
list of renewable sources
biomass (emits greenhouse gases), wind, HEP, geothermal, tidal, wave, solar
