- 1what is a natural resource?materials provided by the Earth that people make into something they can use
- 2what is a biotic resource?obtained from the biosphere and capable of reproduction
- 3what is an abiotic resourceobtained from the lithosphere, atmosphere and hydrosphere. they are all the non-living things in an area
- 4what is a non-renewable resource?combustible (can burn) sources that can’t be ‘remade’. formation takes millions of years
- 5which of these is a biotic resource: soil, cow, wind, coalcow
- 6which of these is an abiotic resource: oil, fresh water, hydro-electric power, treesfresh water
- 7which of the following is a non-renewable source of energy: animals, gas, wind, solargas
- 8which of the following is a renewable source of energy: solar, uranium, coal, birdssolar
- 9exploitation is…the act of using natural resources in a non-sustainable way
- 10overgrazing is…grass that is grazed so heavily that the vegetation is damaged and the ground becomes liable to erosion
- 11overfishing is…when fish sticks are reduced below acceptable levels
- 12palm oil is…oil from the fruits of certain plants. it is used in foods such as chocolate bars, ice cream and pizza. it is also used in other non food products, such as lipstick and soap
- 13groundwater is…water stored underground in rocks and soils
- 14deforestation is…the cutting down and removal of all of most of the trees in a forested area
- 15why does population increase lead to the exploitation of water?the need for water increases, (for drinking, washing and producing manufactured goods)
- 16water is exploited because it is misused. identify an example of this.during the extraction of minerals or the disposal of sewage
- 17how does the exploitation of water reduce water quality?when minerals are extracted, toxic -by products can be washed into rivers
- 18for example, when oil was extracted in Ecuador, 18 billion gallons of toxic waste was dumped into which river?Oriente
- 19how does the exploitation of water reduce biodiversity?when groundwater is used at a faster rate than it can be replenished
- 20what impact has population increase had on farmland?farmland is now being overgrazed
- 21what negative impacts does overgrazing result in?soil is left exposed to the weather and can be eroded, washed or blown away
- 22what has happened to tropical rainforests due to the increase in demand for food?Deforestation - trees are felled to make room for farming such as cattle ranching in the Amazon
- 23there will be a loss of biodiversity when trees are cleared. give an examplebiodiversity is under threat in Cameroon (48% is covered in rainforest) due to 70,000 hectares being cleared
- 24why is overfishing occurring?demand is so great that the fish stocks cannot replenish themselves
- 25what changes to the marine environment does overfishing bring?reduction in biodiversity - if some species are reduced it has a knock-on effect on the food chain. a decline in fish stocks could lead to untapped parts of the ocean being exploited
- 26what energy resources have been exploited?fossil fuels such as coal, oil and natural gas
- 27why does exploiting fossil fuels reduce air quality?because of the gases it produces, such as sulphur dioxide, carbon dioxide and carbon monoxide
- 28why does exploiting fossil fuels reduce biodiversity?burning of coal causes acid rain, which results in trees in forests dying
