How well do a mineral resist scratching?
hardness.
What hard rock is used to make roads?
the rock which is having hardness above 7 like quartzite is the best for road construction depending upon load capacity..
What is the hardest mineral and what is its hardness on the Mohs scale?
Answer 1Mohs Hardness Scale is a comparative way of measuring the hardness of a rock or mineral - that is, its resistance to scratching. It is usually used with minerals because rocks tend to have a heterogeneous consistency and therefore varying degrees of hardness.The Mohs scale goes from 1 to 10, with one being the softest mineral and ten being the hardest. There are minerals that are considered "indicators" and are known to have a specific, constant hardness value. These indicator minerals, with their hardness values, are:Talc: 1 (softest)Gypsum: 2Calcite: 3Fluorite: 4Apatite: 5Feldspar: 6Quartz: 7Topaz: 8Corundum: 9Diamond: 10 (hardest)A set of common objects with known hardness values is often used to estimate the hardness of an unknown sample, by attempting to scratch it. The average human fingernail has a hardness of 2.5 and a copper penny has a hardness of 3.5. A stainless steel blade is about 6.5 and a section of average window glass is approximately 5.5._______________________________________________________Answer 2The Mohs scale of mineral hardness is based on the ability of one natural sample of matter to scratch another mineral. The samples of matter used by Mohs are all different minerals. Minerals are pure substances found in nature.1 = talcum, softest10= diamond, hardestFurther reading via 'Related links'A Mohs hardness scale is a graph. This graph shows information on the body and the hardness.
Is igneous rock harder or softer than metamorphic rock?
There are types of igneous rocks that are hard (eg granite) and others that are soft (eg volcanic ash). There are types of metamorphic rocks that are hard (eg gneiss) and others that are soft (eg marble). Thus "hardness" is not a characteristic that can be used to distinguish between the two.

What is the scale used to measure the softast mineral?
The Mohs Hardness Scale. PS: Talc is one of the softest minerals
How can you find the hardness of the rock?
The Mohs hardness scale is a commonly used hardness scale for minerals. It is on a scale from 1 to 10 (1 being the softest and 10 being the hardest). You can purchase Mohs hardness kits which has a variety of minerals with known hardnesses that you can test your rock against. What you will do is try and scratch your rock with the minerals in the kit. If the mineral in the kit removes material from your rock then your rock is softer. Continue up or down the scale until you find where your rock lies, probably in between two rocks. It will be difficult to measure if your rock is something like sandstone or has an inconsistent composition because certain parts of the rock will be harder than others and sandstone has a very loose bond. Talc (1 on the scale) is one of the softest minerals and diamond is the hardest (10 on the scale). Onyx is also very hard (9 on the scale). If you don't have a scale then you can use your fingernail which is approximately 2.5, a penny is approximately a 3.5, glass is a 5.5, and a knife is a 7.
What is moh's scale used to measure?
The Mohs scale is used to measure the relative hardness of a material. It is based on the ability of one material to scratch another.The scale start at the soft end with Talc, through to Diamond as the hardest.
What distinguishing physical feature is used in identifying Igneous rocks?
Hardness of rock (by using mohr's scale)
What is the word used to describe the relative hardness of minerals?
The Mohs Scale is what is used to measure the relative hardness, or scratch resistance, of minerals. Mohs hardness often agrees with absolute hardness, which is another way of measuring the relative hardness of minerals.
