Explanation:

Trade is the transfer of goods and services from one place to another. Trade is a means of exchange of goods and services in a place.

Earth resources are not evenly distributed across the earth. A host of geologic factors affects how natural resources are distributed in the subsurface. Some countries have vast deposits of resources while others are lacking. Some countries have more than they can use.

Since no country is an island on its own, trade guarantees the distribution of naturally occurring resources in return for other rewards. Oil in the middle East for example is highly coveted by the Western world and America, it is influential to their vast industrialization ambition and drive. Uranium from Niger Republic is very important for power generation in France. Some rare earth metals in Congo are used as component for making mobile phones and electronics, it is exchanged for other pressing resources. Trade is what facilitates this exchange.

The value of a good is measured up and the equivalent is returned back.
