Answers with Explanations:
1. Why is knowledge of mineral properties important?
Knowledge of mineral properties is important because it helps scientists know about the earth's history, particularly when it comes to "rock formations." It is also essential in order to know which minerals are economically important.
2. Which properties might be useful in construction?
Minerals have many physical properties (color, crystal form, hardness, luster, density, cleavage and fracture, etc.)
When it comes to construction purpose, the mineral's malleability is very important. This is the reason why "iron" is one of the most important minerals being used in buildings. It's malleability allows it to be framed into "steel," which is then used to make even bigger infrastructures and skyscrapers.
3. In jewelry-making?
When it comes to "jewelry-making," the hardness and luster of the mineral may be used as a basis. For example, the diamond can be determined from the rest of the minerals because it is the hardest and it has a brilliant-kind of luster.
