Study Notes
Natural Resources
- Natural resources are components of the environment that are useful to humans.
- A resource's value depends on its usefulness and the technology available to exploit it.
- Resources are not fixed, they become valuable when people find a use for them.
Flint as a Resource
- Flint is a mineral found in sedimentary rocks.
- In the Stone Age, flint was valuable due to its sharp edges and ability to create sparks.
- Flint's sharp edges made it possible to create cutting tools, arrowheads, and spearheads for survival.
- Flint's ability to create sparks ignited tinder, providing fire for heat and tools.
- Flint was also used in flintlock firearms for over two centuries.
Resource Categories
- Resources are split into four categories: renewable, non-renewable, flow, and other.
- Renewable resources: Continuously replenished naturally at a rate that allows sustainable use.
- Examples: soil, forests, fish
- Non-renewable resources: Formed slowly over millions of years, with limited supply.
- Examples: fossil fuels (like coal, natural gas), minerals (like gold, iron ore)
- Flow resources: Constantly produced by nature, unaffected by human activity.
- Examples: sunlight, wind, water currents
- Other resources: Do not fit into the other categories, often attracting tourism.
- Examples: Northern Lights, Rocky Mountains, Niagara Falls
Non-Renewable Resource Types
- Some non-renewable resources are recyclable, meaning they can be reused.
- Others are non-recyclable and are destroyed upon use.
Non-Renewable Resource Supply
- Increasing the supply of non-renewable resources requires further scientific research and exploration.
Hydroelectric Energy Generation
- Dams convert the energy of flowing water into electrical energy.
