What else can I help you with?
Can you give examples of minerals from softest to hardest?
Talc - softest Gypsum Calcite Fluorite Apatite Orthoclase feldspar Quartz Topaz Corundum Diamond -hardest
What two minerals are harder than calcite but softer than quartz?
Fluorite and apatite are two minerals that are harder than calcite but softer than quartz on the Mohs scale of mineral hardness. They have hardness values of 4 (fluorite) and 5 (apatite) respectively, compared to 3 for calcite and 7 for quartz.
What can scratch fluorite?
Fluorite is a relatively soft mineral with a Mohs hardness of 4, so it can be scratched by harder materials like quartz, topaz, and corundum. However, fluorite can scratch materials with a lower hardness, such as gypsum and calcite.
What is the order of the minerals from the softest to the hardest?
The order of minerals from softest to hardest is: talc, gypsum, calcite, fluorite, apatite, orthoclase feldspar, quartz, topaz, corundum, and diamond. This scale is known as the Mohs scale of mineral hardness.
Which mineral had 4 directions of cleavage?
I think Calcite. Calcite is 3 on the hardness scale and sometimes you can break it into cubes. The difference between Calcite and Quartz is that Calcite is a milky white.

What is the hardest mineral in this group a. calcite b. quartz c. diamond d. gold?
C.
What are the ten minerals of themohs scale?
The basic Moh's hardness scale consists of: 1. Talc (softest) 2. Gypsum 3. Calcite 4. Fluorite 5. Apatite 6. Feldspar 7. Quartz 8. Topaz 9. Corundum 10. Diamond (hardest)

What is a mineral that fluorite can't scratch?
Fluorite is unable to scratch feldspar, quartz, corundum, diamond, or any other mineral with a Mohs hardness greater than 4.
Is fluorite the biggest mineral in the world?
No, fluorite is not the biggest mineral in the world. While fluorite can form large crystals, there are other minerals such as quartz, feldspar, and calcite that can also grow to significant sizes. The size of a mineral can vary depending on the specific geological conditions in which it forms.
Which is the hardest mineral among corundum quartz and topaz?
Using the geological Moh's scale of hardness of minerals: 1 - Talc 2 - Gypsum 3 - Calcite 4 - Fluorite 5 - Apatite 6 - Feldspar 7 - Quartz 8 - Topaz 9 - Corundum 10 - Diamond
What minerals would scratch fluorite - talc quartz or calcite?
Fluorite with a Mohs hardness of 4 would be scratched by quartz (with a hardness of 7). Both calcite (Mohs hardness 3) and talc (Mohs hardness 1) are softer than fluorite.
What is a ranking of minerals from sofest to hardest?
Well the mohs hardness scale, goes upwarda by 1 everytime and diamond (10) being the hardest is Talc Gypsum Calcite Flurite Appatite Fieldspat Quartz Topaz Corundum Diamond
