What is a common mineral in solid form? A rock _ _ _ _?
Yes violet, its rock salt because as the rock is currently in a rock shape it can dissolve and then become a different shape.
Yes. It could be rock salt.

The answer you're looking for is "A rock is a common mineral in solid form." However, I must clarify that rocks are not minerals themselves; they are composed of minerals. Minerals are naturally occurring inorganic substances with a specific chemical composition and a crystalline structure. Rocks, on the other hand, are made up of various minerals combined together.
To identify a common mineral in solid form, you can follow these steps:
1. Observe the physical properties: Look at the color, luster (how it reflects light), hardness (resistance to scratching), cleavage (tendency to break along certain planes), and specific gravity (density compared to water) of the mineral.
2. Conduct a streak test: Rub the mineral against a porcelain streak plate to determine its color when powdered. The color of the streak can sometimes be different from the mineral's overall color.
3. Perform a hardness test: Use the Mohs scale of hardness to determine the mineral's resistance to scratching. For example, if the mineral can be easily scratched by a fingernail, it may be gypsum.
4. Check for cleavage: Observe how the mineral breaks. Some minerals have distinct planes of cleavage, which means they break along specific directions.
5. Use a magnifying glass or microscope: Close observation can help you identify the mineral's crystal shape. Some minerals have characteristic crystal forms, such as halite (salt) with cubic crystals.
By examining these properties, you can identify common minerals like quartz, feldspar, mica, calcite, or hematite, which are often found in rocks.
