Do minerals have a hardness of 4 or greater?
There is a scale of mineral hardness therefore obviously some will be softer than "4" and others harder because "4" is jut one point on that scale.
What minerals are used to make the color lavender?
There are many minerals that show a purple color. Some of the most common are: amethyst (quartz), garnet, corundum and fluorite. Other mineral properties such as cleavage, hardness, fluorescence and crystal habit can be used to distinguish between the different minerals.
5. Which of the following is a chemical property color freezing point ability to react with oxygen hardness?
Reactivity is a chemical property; all the others are physical properties. (Color is ... kinda iffy; you could make a case for it being a property of the electronic structure of the material in some cases.)
What are some minerals in silicates?
silicates are minerals so perhaps you mean what elements are in silicates? , OR are you asking what are some silicate minerals?
What are two things that make some minerals like diamonds more valuable than others?

Because it is :P
How do minerals contribute to the hardness of rocks?
Some minerals have varying hardness according to the direction you may scratch
Why can some minerals be used as gemstones?
The most valuable gemstones are the clear, crystalline form of the harder minerals such as diamond, corundum, tourmaline, topaz, and garnet. Other minerals with exceptional clarity or color, and even some rock types are known commercially to be valuable as gemstones, but hardness is a key to frequent wearability.
What properties of minerals are considered special properties that apply to only a few minerals?
Those would be properties like magnetism, fluorescence, triboluminescence.
Why are some minerals easier to identify than others?
Minerals vary in ways they can be distinduished. Some are easy to identify by hardness, color , streak, or luster
Are some rocks harder than other rocks?
Absolutely, based on the hardness of the minerals that compose them.
What are some valuable minerals that come out of volcanoes?
Sulfer and Igneous rock
Is Magnetism is a special property of some minerals?
Yes
Do minerals have a hardness of 4 or greater?
There is a scale of mineral hardness therefore obviously some will be softer than "4" and others harder because "4" is jut one point on that scale.
Why is color not a good property to use to identify mineral?
because the color of a mineral can be the same as some other minerals but all minerals have a different property between them
Why is color often an unreliable property in identifying minerals?
because many minerals are the same color, and some minerals come in many colors
What is the property that causes some minerals to break along smooth flat surfaces?
This property is called cleavage.
