What is stratification
Layers
What is a top down organisation
Governments set these up, and usually are on a more larger scale and expense
What are bottom up organisations
These are usually set up by individuals or communities. They are on a smaller scale and expense
What is sustainability
Maintaining resources at a certain level / rate without compromising future generations.
What are the 3 main water supply problems facing the UK?
Ageing infrastructure
Seasonal imbalance
Overpopulation - rainfall imbalance
What is consumption
The intake of a resource
What does scarcely populated mean
Not a lot of people in an area, not compacted
What does densely populated mean?
A lot of people in an area, compacted
What is infrastructure
Pipes
What is irrigation
Artificial water to water the plants and crop
What are cottage industries

What is precipitation
Any form of liquid falling from clouds- rain, snow, sleet and hail
What are abiotic resources
Non living resources
What are biotic resources
Living resources
What are renewable resources
Resources that are inexhaustible,
Name renewable resources
Solar, wind, HPE, biomass, food
What are unrenewable resources
Exhaustible resources that can run out
Name unrenewable resources
Fossil fuels- oil gas and coal. Battery acid.
What are the worlds highest consuming countries
Japan USA Russia
What are the worlds lowest consuming countries
Asia, Africa South America
In developed countries what percentage of water is used in industry, agriculture and domestic?
57% 33% 10%
What is water scarcity / water deficit
Not having enough water to meet the demand
What is a water surplus
Having an abundance of water, meeting the demand and going over.
The US has 5% of the worlds population, what percentage of the worlds oil do they use?
20%
Why are they fewer farmers in developed countries than developing countries
It’s more mechanical, efficient in industry/domestic sectors and food is imported. They usually are tertiary, quaternary or secondary.

450000 litres
What are the main two reasons why water scarcity is an issue
+80 million more people yearly and global distribution
Why are countries with abundant water supplies more likely to have a high level of manufacturing?
Water used in manufacturing allows trade
Name two countries with a water surplus
Uk and America
Name 2 countries with a water deficit
Africa and India
What is water stress
Where demand is higher than the supply and therefore the accessibility is lower.
Name two factors that affect water availability
Climate - little rainfall
And geology
What is abstraction
Taking of groundwater
Why are developing countries struggling to maintain water availability
Lacking of technology to transport water. Poor water quality
Why are more countries developing and becoming emerging countries leading to an increase water use
Industrialisation
What is desalination
Water is filtered through beds of different sediment, removing harmful contents. Sea water is removed of its salt content and filtered into pure and useable water.
State advantages of desalination
Improved water supply in scarce areas
Plentiful supply - comes from the sea/ ocean
Makes saline water drinkable and clean
Lessens the demand in groundwater use
Successful in over 100 countries
State disadvantages of desalination
Very technical, needs an experienced and knowledgeable workforce to clean the filters
Fish can get sucked into the filters
Expensive to repair or reinstall
