Explanation
Resources are materials or substances present in nature that satisfy human needs. They are often classified based on the type of value they possess. Economic value refers to resources that can be bought and sold for profit, whereas aesthetic value refers to resources that provide pleasure, beauty, or psychological well-being but do not necessarily have a direct commercial price tag.
Option Analysis
- Iron ore deposits is Incorrect: Iron ore deposits are mineral resources used as raw materials for industries (e.g., steel production). They are traded commodities with a specific market price, possessing direct commercial economic value.
- Scenic landscapes is Correct: Scenic landscapes (such as mountains, waterfalls, or forests) possess aesthetic value. They satisfy the human need for beauty and recreation. While they may indirectly support economic activities like tourism, the resource itself is primarily valued for its natural beauty rather than as a tradable commodity.
- Coal reserves is Incorrect: Coal reserves are fossil fuels used for energy generation and industrial applications. They are critical economic assets with high commercial value.
- Petroleum fields is Incorrect: Petroleum fields are sources of crude oil, often termed "Black Gold." They are highly valuable commodities in the global market and possess significant commercial economic value.
Key Takeaway
Time and technology are two important factors that can change substances into resources. Some resources like metals and fossil fuels have economic value, while others like a beautiful landscape have aesthetic value; however, both are important as they satisfy different human needs.
