Classifying Earth’s Resources Renewable, Nonrenewable and Inexhaustible Renewable Resources • Definition- a resource that can be replaced in a short amount of time. Examples of Renewable Resources • • • • • Fresh Water via the water cycle Plants via the life cycle Animals via the life cycle Air via the process of photosynthesis Soil via decomposition of matter and bacteria Fresh Water Life Cycle of a Plant Erosion Protectors Food Decoration Medicine Shade Building Material Sun Protection Oxygen Producers Animals- The Circle of Life Food Pollen Carriers Seed Carriers Clothing Entertainment Medicine Companionship Pollen Carriers Carbon Dioxide Producers Air Cycle- Photosynthesis To Breath To do Science To Regulate Earth’s Temp. To Sustain Plant Life To Make Fire To Make Rocks Soil Soil is dynamic and is filled with all kinds of life… such as microbes, worms, fungi, insects, roots and more. It contains minerals and small rocks that vary in size from that of silt to pebbles. Soil also usually contains organic matter which is the decaying remnants of plant and animal life. It can take hundreds or thousands of years to make 1 inch of soil Inexhaustible (HUH?) Resources • Definition- resources that cannot be used up. • Oh wait……scientists don’t classify resources an inexhaustible….so keep going with – RENEWABLE!! Examples of MORE Renewable Resources • Wind • Ocean Tides • Sunlight Wind Wind can be harnessed to store energy as electricity or used directly to pump water Ocean Tides The movement of the tides could be harnessed with an underwater turbine to store the energy. Sunlight We can use sunlight to generate electricity by using solar panels and we already know that the sun is the energy source for the water and for photosynthesis. Nonrenewable Resources • Definition- a resource that cannot be replaced in a short amount of time. Examples of Nonrenewable Resources • Diamonds and Precious Gems • Metal Ore • Fossil Fuels such as Coal, Oil, and Natural Gas Precious Gems Metal Ore Iron ore Platinum ore Fossil Fuels What Can We Conclude About Earth’s Resources? • How do we classify earth’s resources? • What are some examples of each type of resource? • Should we be more careful with two types of resources than the other one? • What can we as individuals do to help conserve some of our most important resources?
