Define the term renewable resource
Renewable resources are those that will not run out as more can be made, they will replenish themselves over time
Define the term Non renewable resource
Non renewable resources are those that are likely to run out as they are being used up faster than they could ever be made, they will not replenish over time or they will take a very long time to do so
Examples of renewable resources
Water Wood Animal and plant products Sunlight Wind Tidal They are things we harvest from nature and are sustainable if managed properly
Non renewable resources examples
Oil Coal Natural gas Uranium All metals mined from the earth
Explain why fossil fuels have their name
They are called fossil fuels because they are formed by the fossilisation of plants and marine animals
Identify uses of fossil fuels
Fossil fuels are used for Petrol and other vehicle fuels Electricity generation Plastic production Heating
Outline the process for the formation of coal
When ancient plants died millions of years ago, they formed thick layers of rotting materials on forest floors and swamps
Under pressure from the layers above, the material turned into peat
Sea levels fell and rose again, sediments were deposited on top of the peat
Heat and pressure from the layers of sediment turned the peat into Lignite
More heat and pressure turned it into bituminous coal and then eventually, black coal
Outline the process for the formation of oil and natural gas
Remains of tiny sea animals and plants were buried on the ocean floor by sediments
After millions of years of squeezing and heating, they formed sedimentary rocks
Chemical reactions within the rocks slowly changed the remains of the sea organisms into oil and natural gas
The oil and natural gas move up until they are stopped by a layer of non porous or impermeable rock
Identify common minerals
Antimony Asbestos Barium Bauxite Beryllium Chromite Cobalt Copper Feldspar
Define the term Ore
A compound or mixture of compounds from which it is commercially profitable to extract a desired substance such as metal
Process used to extract a metal from an ore
Mining to take the ore out of the ground
Milling to purify the ore
Smelting to extract crude metal from the ore
Refining to purify the crude metal
Define lithosphere and common elements in each
??
Define hydrosphere and common elements in it
??
Define atmosphere and common elements in it
??
Define biosphere and common elements in it
??
Identify resources that can be extracted from each sphere
??
Define the term recycling and identify common household items that can be recycled
Recycling is the action or process of converting waste into reusable material Books Cardboard Disposable plates and cups Batteries CD and DVD cases
Identify the use of plastic codes
Plastic codes identify the type of plastic the product is made from
The process of recycling aluminium cans
Cans are collected and stored
Cans are screened to remove any made of other metals
Cans are crushed
Cans are weighed
Cans are formed into large blocks then transported to a furnace
Cans are melted, poured into moulds and cooled
The ingots are rolled into thin sheets and made into new cans
Define mining
Mining is a process that involves the removal of useful ores and other materials from the earth
Identify different types of mines
Open cut Strip Quarry Alluvial Underground
Factors that need to be considered before mining can take place
Amount of resources available Type of mining necessary Cost Location of mine Environmental cost of putting the mined area back to a usable state Cost of compensation Endangered animals of the site
Viewpoints of stakeholders in mining
Local residents-
Increased noise, damage to environment, increased traffic
Mining companies-
Increased income, increased availability of resources
Governments-
Increased employment, improved economy
Environmental groups-
Damage to environment and animal habitats
Scientists-
Increased employment t and availability of resources
What is the purpose of EIS and the factors they consider
This is a document that a company must produce before mining, drilling or construction operations can commence
It pretty much is a contract to stop mining comparing from damaging the environment and making sure they return the land to its original state
