Can apatite be scratched by quartz?
No, apatite cannot be scratched by quartz. Apatite is harder than quartz on the Mohs scale of mineral hardness, with apatite having a hardness of 5 and quartz having a hardness of 7.
What minerals have a hardness of 7 on the mohs scale?
Minerals that have a hardness of 7 on the Mohs scale include quartz, beryl (which includes emerald and aquamarine), and garnet. These minerals are relatively hard and can scratch materials with a lower hardness rating.
what is hardness of feldspar?
Feldspars generally have a hardness of 6 on Mohs' hardness scale.
What is the hardness of dolomite?
The hardness of dolomite ranges from 3.5 to 4 on the Mohs scale. It is softer than most other minerals and can easily be scratched by harder minerals such as quartz or topaz.
What do scientists use to determine mineral hardness?
Scientists use the Mohs scale of mineral hardness to determine the relative hardness of minerals. This scale ranks minerals from 1 (softest) to 10 (hardest) based on their ability to scratch or be scratched by other minerals. By performing a scratch test, scientists can identify a mineral's hardness by comparing it to known minerals on the Mohs scale.
Is 7on MOHs hardness scale strong?
Yes, 7 on the Mohs hardness scale is considered strong. It indicates that the mineral can scratch minerals with a lower number but can be scratched by minerals with a higher number. Minerals like quartz and topaz have a hardness of 7 on the Mohs scale.
Can apatite be scratched by quartz?
No, apatite cannot be scratched by quartz. Apatite is harder than quartz on the Mohs scale of mineral hardness, with apatite having a hardness of 5 and quartz having a hardness of 7.

what is hardness of feldspar?
Feldspars generally have a hardness of 6 on Mohs' hardness scale.
What is the hardness of dolomite?
The hardness of dolomite ranges from 3.5 to 4 on the Mohs scale. It is softer than most other minerals and can easily be scratched by harder minerals such as quartz or topaz.
Can quartz be scratched by a penny?
No. According to Mohs Hardness Scale, Quartz has a hardness of 7 while copper has a hardness of about 3. The higher number indicates a greater hardness.
What is hardness when referring to minerals?
Its ability to be scratched. That is also determined on mohs hardness scale
What other minerals can sulfur be scratched by?
Sulfur is a relatively soft mineral, with a hardness of 2 on the Mohs scale. It can be scratched by minerals with a higher hardness, such as calcite (3 on the Mohs scale) and fluorite (4 on the Mohs scale).
If a mineral is a 6 on the mohs scale what can it be scracted by?
A mineral with a hardness of 6 on the Mohs scale can be scratched by anything harder than a 6, such as minerals with a hardness of 7 or higher. It will not be scratched by minerals with a hardness of 5 or lower.
What is the hardness of anorthosite?
Anorthosite has a hardness ranging from 6 to 7 on the Mohs scale of mineral hardness. This means it is harder than most common materials but can still be scratched by harder minerals like quartz or topaz.
Will the mineral topaz scratch quartz or will quartz scratch topaz Why?
Topaz will scratch quartz because its hardness on the Mohs scale is 8, while quartz has a hardness of 7. Harder minerals can easily scratch softer minerals.
What is the classification of a rock that cannot ba scratched with a fingernail but can be scratched with a coin?
The rock would likely be classified as having a hardness of around 3.5 on the Mohs scale of mineral hardness. This would indicate that the rock is softer than minerals like quartz but harder than minerals like calcite. Examples of rocks with this hardness include gypsum and calcite.
