The highest level on the Mohs hardness scale is a level ten. Diamonds are at a level ten and are also intrusive rocks.
However Intrusive rocks can be at almost any level of hardness based on the minerals the rock contains.
Flint rocks have a hardness of around 7 on the Mohs scale, which makes them relatively hard and durable. This hardness is due to the presence of silica in the composition of flint rocks. These properties make flint rocks suitable for various uses, including as tools and for sparking fires.
Diatomite has a hardness of around 5.5 on the Mohs scale of hardness.
This scale is correctly called the Mohs scale. Scientists use this scale to measure a rock's hardness or softness. They can discover how hard a mineral or rocks is and drill in to it and find out more about it.
On the hardness scale it is 6.5-7.
On the Mohs Scale of Hardness, chert has a hardness of 7.
It is about 2.5 in the Mohs Hardness Scale.
The hardness of the mineral pyrite, or Fool's Gold, is about 6 on the Mohs hardness scale. That's a little harder than a steel knife blade, but not as hard as the mineral quartz
Answer A natural of cultured pearl's hardness ranges from 3.5 to 4.5 on Mohs' scale.
Rocks that are harder than a nail, which typically has a hardness of around 5 on the Mohs scale, include quartz, topaz, and diamond. Quartz, with a hardness of 7, is commonly found in various types of rocks. Topaz ranks at 8, while diamond is the hardest known natural material, scoring a 10 on the Mohs scale. Other hard rocks include corundum and garnet, which also exceed the hardness of a nail.
Quartz has a hardness of 7 on the Mohs scale, making it relatively hard and durable.
like a 7.
The hardness of uranium is 6 on the Mohs scale; not so hard.
