Natural Resources Study Guide Test Date: ____________________________________ Please study the following terms/ideas and make sure that you are able to list examples of each. *Resource: a material that is found in nature and used by living things (example: air, water, gasoline, metals, coal, oil) *Resources come from below, on and above the ground. Here are some examples of each: Below-diamonds, coal, oil, iron On- water, trees, plants, soil Above- air *There are two basic types of resources; renewable and nonrenewable. 1. Renewable Resources: resources that can be replaced in a human lifetime (ex: trees, plants, air, water) 2. Nonrenewable Resources: resources that will be used up someday (ex: coal, oil, iron, copper) *Fossil Fuels: Formed from decayed plants and animals (it takes millions of years for fossil fuels to form in the Earth’s crust). Fossil fuels are used as an energy sources (used to heat homes and to make fuel for cars). When the “fuels” are burned, heat is released and then turns into energy. (Examples: coal, oil, natural gas) *Energy is also a natural resource. *Solar energy-energy from the sun *Fossil fuels, wind energy and water energy all come from the sun. *The sun is the source of almost all energy on Earth. We use the sun for light and heat energy. A lot of our body energy come from food. We get a lot of our food from plants and the plants need sunlight to grow. *The force of flowing water and moving air (wind) can also be used to produce “electricity.” Strong winds (using a windmill) and water pressure will help “spin” a generator and then electricity will be produced. *Recycling- reusing a resource to make something new, this also reduces pollution (you can recycle paper, glass, plastic and metals) *Conserving: to “save” a resource You can’t recycle all resources but you can CONSERVE them. This will help them last longer. Examples: use less heat or air condition in the house, take a shorter shower, and carpool with a friend (to save gas)
