1 Natural resources are materials found in nature. Some ,such as sunlight ,are found almost everywhere. Others, like oil, are found only in certain areas. Some places have many natural resources , while others have only a few. : h) t+ }5 G5 F& p, D2 Z
2 The different kinds of natural resources are air ,water, soil, sunlight ,minerals, fossil fuels, and animals life. Some of these air,water, soil, and sunlight are needed for life to exist. For this reason ,they are sometimes viewed as the most important resources . other kingds of resources are still important . one of there is minerals , or nonliving substances found beneath Earth’s surface. All through history, people have used such minerals as iron ,copper,tin, and gold to make tools ,weapons , jewelry, and money . fossil fuel ,such as coal , oil, and natural gas, provide the energy to heat homes and power machines. ; f.

3 Natural resources become valuable only when people learn how to use then, for example, Marco Pole ,who once made a journey to china, returned to his native city of Venice. A few years later, he wrote about his travel s and described many wonderful things he had seen. One of these was a black rock ,now known as coal ,which the Chinese dug out of the ground and burned to keep warm . the Venetians did not believe him. To them ,coal was not a natural resources . people later change their minds when they found out that it could be used as a fuel to power steam engines and to process steel.

4 Some resources can be replaced by nature as they are used up .these are renewable resources .for example ,American farmers who lived in the Dust Bowl were able to get back their once –rich soil by using better ways of farming and by planting trees to keep the soil from being worn away. Other natural resources cannot be replaced once they are used up. These are nonrenewable resources. Once Earth’s coal, soil ,and natural gas are used up ,they will be gone forever. 2 h0 {' d1 W$ i4 p" s
5 In recent years ,people become more and more interested in making better use of the world’s natural resources. Some countries are trying to develop new sources of energy . 9 R$ Q) l5 C! r( Y
6 Natural resources affected the location and growth of settlements all through history. Rich soil and plenty of water made farming possible and led to the rise of cities . Asians and Europeans came into contact with one another partly because Europeans wanted the silk and spices of Asia. Modern industry started in those countries that had large amounts of coal and iron ore for making steel. During the 1800s,the discovery of gold in California ,South Africa ,and Australia , and Alaska caused hundreds of thousands of people to move to those areas. 6 J& q' `9 W: ^; z5 Y6 K
