Renewable vs. Non-Renewable Some natural resources can be replaced within a few years or within a human lifetime. These are called renewable resources. Trees, sun, wind, and water are examples of renewable resources. They are resources we most likely will not run out of.Non-renewable resources cannot be replaced at the rate they are being used up. They take hundreds, thousands, and even millions of years to be made. Once they are used up, they are gone! Some examples of nonrenewable resources are the fossil fuels oil, natural gas, and coal. 5.

Coal- to make electricity or heat our homes Wood- an inefficient way to make heat or light Natural Gas- to make electricity or heat our homes Oil- to make electricity, heat our homes, or power our vehicles 13. Alternative Ways to Make Energy Without Using Fossil FuelsSolar PowerWind PowerHydropower 14. Earth Materials Used for Building Structures Iron- bridges and fencesIron is used to make steel which is then used for buildings such as skyscrapers. Stone- houses, fences Brick- (made from clay) houses, buildingsConcrete- skyscrapers Wood- houses 15. The Lorax by Dr. Seuss Click the image to watch. 16. Earth Materials Used for Enhancing Transportation Aluminum- airplanes, cars, bicycles Titanium- airplanes, cars, bicycles Sand and Gravel- making roads Clay- cement and concrete for drivewaysSteel (from iron)- bicycles, cars, trains, ships 17. Earth Materials Used for Making Products Oil- plastic products like your cell phone and PlaystationWood- paper, furniture Plants- medicine, food, clothing (cotton)Soil- crops for food Animals- food for humans, clothing (leather)Clay- plates, bowls, cups, flower pots, statues Copper- inside cords to conduct electricity 18.
