What are four questions asked to determine if something is a mineral?
To determine if something is a mineral, four key questions are often asked: Is it naturally occurring? Is it inorganic, meaning it is not made from biological processes? Does it have a definite chemical composition? Lastly, does it possess a crystalline structure? If the answer to all these questions is yes, then the substance can be classified as a mineral.
How can you determine if a mineral is a mineral?
If you are starting with a mineral, there is no need to determine if it is a mineral. Minerals are naturally occurring inorganic solids, with a specific chemical formula and a crystalline structure. If the material in question does not meet this definition, it probably isn't a mineral.
How do determine the streak of a mineral?
by rubbing the mineral on a rough hard surface

What are 7 ways to determine the identity of a mineral?
Color: Observe the color of the mineral. Hardness: Use the Mohs scale to determine the mineral's hardness. Cleavage and fracture: Check how the mineral breaks. Luster: Determine if the mineral is metallic or non-metallic. Streak: Identify the color of the mineral's powdered form. Specific gravity: Measure the density of the mineral. Acid reaction: Test if the mineral reacts with acid.
What of a mineral will determine if it floats or sinks in water?
The density of the mineral compared to the density of water will determine if it floats or sinks. If the mineral has a lower density than water, it will float; if it has a higher density, it will sink.
What is used to determine a mineral's resistance to being scratched?
The Mohs mineral hardness scale.
