Introduction• Natural resources are minerals or substances that we use for economic

gain.

• In land, some examples of natural resources are wood, oil, coal, iron, and soil.

Nonrenewable & Renewable Resources-Nonrenewable resources are available for a limited time because they take a long time to be replenished. Most of natural resources on land are nonrenewable. -Renewable resources are naturally replenished in short periods of time.

WoodWhen foresters harvest a tree, all parts of the tree are used. Energy is produced from sawmill and harvesting residue in the form of biomass. The lumber is used in carbon-storing building materials and about 5,000 different wood products.

In the U.S. we use the most oil in the country, about

19.15 million barrels of oil per day!

About 40% of oil is used for energy. Oil can be easily extracted from the ground than coal.

Oil

Coal is inexpensive when compared to other

fossil fuels (or alternative energy sources)

Burning coal can produce useful by-products that can be used for other industries or products, and the Electricity produced from coal is reliable

Coal

IronIron is the most used of all metals. It accounts for 95% of worldwide metal productions. Iron is used for the construction of machinery, machine tools, automobiles, hulls of large ships, structural components for buildings and can be combined with alloying elements to make steel.

SoilSoil contributes to determine the way that natural vegetation, crops, and human settlements are distributed on the territory. Soil is important because it plays a role as a reserve of nutritional elements and water and mechanical support for vegetation.
