Once YOU have come up with attempted answers to YOUR questions, please re-post and let us know what you think. Then someone here will be happy to comment on your thinking.
1) you can do from general knowledge
or see http://en.wikipedia.org/wiki/Gold
2) is an interesting question as you need to define the property, before you can state a difference. For example gold is very much more dense than 'ordinary' rock (what ever that is), so there is a big difference. Both 'ordinary' rock and gold are found naturally in the ground, so there is no difference in the source.
3) see http://www.thefreedictionary.com/goldmine
and

1) Two properties of gold that make it economically valuable are its rarity and its durability.
- Rarity: Gold is relatively rare compared to many other minerals. Its scarcity makes it desirable and increases its value in the market.
- Durability: Gold is highly resistant to corrosion, meaning it does not tarnish or rust over time. This makes it a reliable store of value and makes gold jewelry and other gold items desirable for their longevity.
To get this answer, you can search for information about the properties and value of gold in economic contexts. Resources like scientific articles, economic reports, and websites specializing in mining or precious metals can provide detailed information on these properties.
2) The main difference between gold and an ordinary rock lies in their composition and value.
- Composition: Gold is a chemical element (symbol Au) with its own unique properties. It is a dense, soft, and malleable metal. In contrast, an ordinary rock is typically a combination of various minerals and does not contain significant amounts of gold.
- Value: Gold has inherent economic value due to its rarity and unique properties, making it a valuable precious metal. On the other hand, most ordinary rocks do not possess such value unless they contain other economically significant minerals like diamonds or rare earth elements.
To understand the differences between gold and ordinary rocks, you can explore articles, textbooks, or websites that discuss the properties and characteristics of both gold and rocks.
3) The difference between a gold mine and a gold prospect lies in their level of development and the amount of gold present.
- Gold Mine: A gold mine refers to a site where gold deposits have been identified and are being actively exploited for extraction. A gold mine is usually a well-established operation with infrastructure in place for mineral extraction and processing. It involves systematic exploration, mining operations, and processing techniques to extract gold from the earth.
- Gold Prospect: A gold prospect, also known as a gold exploration area, refers to an area where signs of gold deposits have been detected but have not yet been fully verified or developed into a full-scale mine. It could be an area of interest based on geological indicators, such as geophysical surveys or surface sampling. Further exploration and evaluation, including drilling and testing, are required to determine the feasibility and potential of establishing a gold mine.
To obtain information about the difference between a gold mine and a gold prospect, you can refer to mining industry resources, geological surveys, or mining companies' websites that discuss the various stages of gold exploration and mining.
