Natural Resources Chapter 5 Section 1
What are Natural Resources
• Natural Resources- useful material found in the environment • Water, minerals, vegetation • Raw Materials- natural resources that must be changed to be useful – Ex. Trees into paper
• Renewable Resources – Renewable resourcesresources that can be replaced – Water – Wind – Solar energy – Geothermal energy
• Living Resources – Plants and animals – Ex. Trees – Eggs – Chickens – Cows – Living renewable resources must be managed to ensure they are not used completely used up
• Nonrenewable Resources – Nonrenewable Resourcesresources that cannot be replaced – Ex. Crude oil – Natural Gas – Most Minerals – Collection must be managed – Substitutes must be developed – Most can be recycled
• Fossil Fuels – Fuels created over millions of years from remains of prehistoric living things – Ex. Coal – Petroleum – Natural Gas – They are both renewable and nonrenewable at the same time
A Special Resource: • Energy canEnergy be gotten from- wind,
sun, fossil fuels, • Energy is needed in order to make other natural resources. • Ex. Trees needs the sun fossil fuel needed to harvest the trees Water energy needed to turn it into paper (falling water can produce energy)
• Energy “Have’s” and “Have Not’s” – Energy is needed by everyone, but not evenly distributed around the world – Canada and Norway- lots of water – Saudi Arabia and Mexico- lots of oil – U.S. and Japan use more energy than they produce so they have to buy energy
• Meeting Future Needs – Limited fossil fuels – Atomic energy – Tidal energy – Geothermal Energy – Nuclear Energy – Conservation is key to making resources last – Pollution and population also play a role in meeting future needs
