biotic

living things (plants, animals)

New cards
2

abiotic

Non-living things (rocks, soil, water)

New cards
3

renweable resource

environment continues to supply or replace

New cards
4

Non-renwable resource

a resource used faster than it can be re-made

New cards
5

why are we using more natural resources nowadays ?

more people, more industry, lifestyle choices

New cards
6

why is water needed

drinking, cooking, washing, producing goods, agriculture

New cards
7

how is water exploited?

it is wasted and misused, increased demand. in mining toxic byproducts can be washed into water sources, sewage contaminating sources

New cards
8

consequences of water exploitation

causes problems for animals and vegitation, decreasing biodiversity. toxic products/ sewage contaminate the water

New cards
9

why if food needed

to feed the ever increasing population - can be done through deforestation for farming, intense cultivation and over fishing

New cards
10

how are environment exploited for food

overgrazing, deforestation, overfishing

New cards
11

overgrazing

reducing in soil quality

New cards
12

deforestation

rainforest trees cut to make way for cattle ranching

New cards
13

overfishing

increased demand reduced ocean stock- we've removed around 2/3 of the large fish pop, fishing techniques cause destruction to the sea floor

New cards
14

what are the consequences of fishing and farming exploitation?

over grazing and deforestation can lead to soil erosion and reduction in soil fertility. overfishing has led to reduced biodiversity in the oceans changing the ecosystem

New cards
15

why is energy needed?

to meet the demand from humans

New cards
16

how are environments exploited for energy?

oil, gas and coal are exploited through mining

New cards
17

consequences of exploitation for energy?

extraction and production of energy from fossil fuels can cause reduction in air quality because of greenhouse gases (co2/so2). acid rain produced by burning fossil fuels creating (so2) - damages buildings, plants and aquatic life

New cards
18

oil extraction in ecuador

during 1960's, oil discovered in a place home to indigenous tribes. oil extraction involved pipelines cracking and waste pits filled with toxic sludge overflowing causing pollution and risking the health of the indigenous population

New cards
19

deforestation in Cameroon

covered in 48% of rainforest - 1% cut down each year for palm oil plantations. impact biodiversity, soil erosion which is a big problem for food security

New cards
20

overfishing in the north sea

in last 50 yrs unsustainable fishing practises resulted in critical fish pop levels. 300,00 tons in 1970 fell to 20,000 tons in 2006

New cards
21

where is there gold in africa

east coast and north west

New cards
22

where is there oil in africa

niger, chad, sudan

New cards
23

where is there gas in africa

north coast

New cards
24

where is there coal in africa?

not much

New cards
25

how does having resources affect the country?

boost economy, TNC's profit from trading, having resources makes it cheaper in that country (US v cheap oil/fuel), having lots could prevent people doing new research

New cards
26

countries which most oil

venezuala, saudi arabia, canada

New cards
27

countries with most gas

russia, iran and qatar

New cards
28

countries with most coal

USA, russia , China

New cards
29

which countries produce at least 5% of worlds wood?

Canada, Brazil, USA

New cards
30

soil and agriculture distribution

broadly sweeping bands across countries

New cards
31

where are diamonds found?

sub-Saharan africa, russia and australia

New cards
32

where is iron ore found?

all continents except africa

New cards
33

food consumption patterns

developed countries have highest levels of food consumption

New cards
34

water usage patterns

amount of water varies (linked to development)

New cards
35

energy usage patterns

globaly = increasing, amount of energy used my a country depends on a number of things including level of development. emerging countries are using an increasing amount of energy to power their developing industries

New cards
36

where are arable ( crops) distributed in the UK?

east of england because flat land = easier for machines, rain shadow

New cards
37

where is cattle distributed?

south west, central = relief rainfall which isnt good for crops

New cards
38

where are hill sheep distributed?

mountainous areas (scotland, ireland, Pennines, lake district)

New cards
39

what is market gardening?

Vegetables

New cards
40

what type of soil is in the Uk?

mostly brown earth and Gley

New cards
41

browth earth soil info

widespread in britain apart from mountainous areas

New cards
42

gley soil info

scotland, areas of high rainfall where water doesnt drain easy

New cards
43

forestry distribution in the UK

concentrated in the North and West of country - 13% of GB land area - one of most highly deforested countries in europe

New cards
44

fossil fuels distribution in the UK

coal - northumberland, south wales.
oil - offshore in the North Sea

New cards
45

water supply distribution in the UK

greatest on the west side result of relief rainfall - piped to areas of high urban pop

New cards
46

what type of rock and minerals in the uk?

UK has a variety for minerals - construction minerals, industrial minerals and fossil fuels

New cards
47

percentage coal

30%

New cards
48

percentage gas

30%

New cards
49

percentage nuclear

19%

New cards
50

percentage renewable

19.%

New cards
51

most used renewable

wind (9.5%)

New cards
52

why does wealth of country impact energy mix?

more wealth = can invest in new green technology (they rely of fuelwood and fossil fuels

New cards
53

how does availablity of resources impact energy mix?

if you have lots of it you are going to use is (UAE + oil and Norway + HEP

New cards
54

how does population impact energy mix?

more people need it = more energy needed. HEP - more control than solar or wind

bhutan energy resource managment : which sources?

HEP, fuelwood

New cards
70

HEP in Bhutan

provides 40% of government income, provides electricity to 95% of households in 2013

why are people trying to stop fuel wood uses in Bhutan?

causes lung problems, deforestation, buring wood produces greenhouse gasess
