What else can I help you with?
What mineral is very easily scratched and found in drywalls of houses?
Gypsum (number 2 on the Moh's Hardness Scale)
What rock is soft enough to be scratched by a nail?
Rocks that mostly contain minerals like mica, gypsum, and talc can be scratched by a fingernail.
What is fluorite on the mohs hardness scale?
Fluorite is the number 4 mineral on the Mohs scale of mineral hardness, above calcite and below apatite.
What is a shiny mineral that occurs in sheets?
Mica is a shiny mineral that occurs in sheets. It is composed of thin, flat sheets that can easily be peeled apart. Mica is commonly found in igneous and metamorphic rocks.
What three question would you ask about minerals?
For simple identification purposes you should ask: what is the hardness of the mineral compared to other minerals; what is the color (streak) of the mineral when scratched on an unglazed porcelain ceramic surface; and does the mineral react with dilute hydrochloric acid or vinegar, indicating whether or not it's a carbonate mineral. Other identifiers would be the mineral's specific gravity, lustre, and crystal classification.

Gypsum (number 2 on the Moh's Hardness Scale)
What unknown mineral is found to scratch apatite and to be scratched by corundum?
The unknown mineral would be topaz. Topaz lies between apatite and corundum on the Mohs scale, making it capable of scratching apatite and being scratched by corundum.

Rocks that mostly contain minerals like mica, gypsum, and talc can be scratched by a fingernail.
What is fluorite on the mohs hardness scale?
Fluorite is the number 4 mineral on the Mohs scale of mineral hardness, above calcite and below apatite.
What is the Flaky dark mineral found in granite?
The flaky dark mineral commonly found in granite is biotite. Biotite is a mica mineral that typically appears as black or dark brown flakes and is characterized by its perfect cleavage, allowing it to be easily split into thin sheets. It contributes to the overall texture and mineral composition of granite, alongside quartz and feldspar.
How does gypsum look like?
Gypsum typically appears as a soft, white or colorless mineral, but it can also be found in shades of gray, yellow, or pink due to impurities. It often forms translucent crystals, which can be tabular or prismatic in shape. The texture can be smooth or fibrous, and it has a characteristic softness, allowing it to be scratched easily with a fingernail. In its massive form, it can resemble chalk or a fine powder.
What is a shiny mineral that occurs in sheets?
Mica is a shiny mineral that occurs in sheets. It is composed of thin, flat sheets that can easily be peeled apart. Mica is commonly found in igneous and metamorphic rocks.
Where is the walfenite mineral found?
This mineral was found in San Francisco,California

Is helium found as a native mineral?
Helium is found as a mono atomic element. It is not found as a mineral.
Where is the California state mineral found?
where is the California s state mineral found
Why is platinum found as a metal not an ore?
Platinum is found in its metallic form because it is unreactive and does not easily combine with other elements to form compounds. This results in it being found naturally as pure metal in deposits, rather than as an ore mineral that needs to be extracted and refined.
