Sioux quartzite
The inner core is the hardest layer in the Earth, consisting mainly of solid iron and nickel. Its immense pressure keeps it in a solid state even though it reaches temperatures of up to 9,000 degrees Fahrenheit.
The softest rock is generally talc, with a Mohs hardness of 1, while the hardest rock is diamond, with a Mohs hardness of 10. Other common rocks fall in between, such as gypsum (2), calcite (3), quartz (7), and feldspar (6-7).
Well, diamond is a mineral so it isn't any type of rock.Diamond is the hardest mineral on earth and a 10 on the 1-10 MOHZ hardness scale. It is 40-50 times harder than the next hardest rock, corundum which is 9 on the scale. So no, diamond is quite the very opposite of soft, and as previously stated, it is a mineral, not a rock.No, diamond is the hardest rock.
Love is often considered the hardest thing on Earth, as it requires vulnerability, sacrifice, and understanding to truly connect with another person on a deep emotional level.
The hardest layer of the Earth is the inner core, consisting mainly of solid iron and nickel. Followed by the outer core which is liquid iron and nickel. The mantle is softer than the core but still solid, made up of hot, flowing rock. The crust is the Earth's outermost layer and the softest of the four layers.
The hardest substance that is naturally occurring is a diamond. However, there are harder substances that have been made by scientists in labs.
The diamond is the hardest rock (or mineral).
Diorite is the second hardest rock in the worl - Vellond
Diamond.

Yes, it is the hardest natural rock on earth.

The second hardest substance after diamond on earth is cubic boron nitride. It is often used as an abrasive and cutting tool material due to its exceptional hardness and thermal conductivity.
Hardest Mineral=Diamond Second would be corundum.etc. etc....but these are minerals. Rocks are a combination of at least 2 minerals. A hard "rock" would be nearly any mafic, igneous rock.
Corundum is a mineral, therefore it could not be the hardest rock.
The hardest matter on earth is Diamond.
