What is harder granite limestone marble?
Granite is the hardest of the three stones, primarily composed of quartz and feldspar, making it highly durable and resistant to scratching. Marble, formed from limestone under heat and pressure, is softer and can be more easily scratched and damaged. Limestone is the softest of the three, primarily composed of calcite, and is more susceptible to erosion and wear. Overall, the hardness scale ranks them as granite > marble > limestone.
What is the hardest mineral in granite?
The hardest mineral in granite is typically quartz, which has a Mohs hardness of 7. Quartz is harder than the other common minerals in granite, such as feldspar and mica. This hardness contributes to the overall durability and strength of granite as a natural stone.
What is harder granite limestone marble or diamond?
Diamond. Diamond is the only mineral on this list. Granite is an intrusive igneous rock, meaning that it formed beneath the surface of the earth. Marble is a metamorphic rock, which means that it formed from another type of rock, or "parent rock," through subjection to intense heat and/or pressure. Limestone is a sedimentary rock composed of calcium carbonate and can often be the parent rock for marble. Please note that the Mohs hardness scale does not apply to rocks. It only covers minerals.
What is the hardest rock between granite and diamond?
The harder rock is diamond
How does granite compare in hardness to diamonds?
Granite is significantly softer than diamonds. On the Mohs scale of mineral hardness, granite scores around 6 to 7, while diamonds rank at a perfect 10, making them the hardest known natural material. This means that diamonds can easily scratch granite, but granite cannot scratch diamonds.
What is the order of hardness for Granite Limestone and marble?
Using Mohs scale of hardness for minerals, you can--with a bit of detective work--find out the hardness of Granite, Limestone and Marble.But I think that we can do a bit of reasoning and figure out for ourselves the order of hardness for these stones.First off, knowing that Limestone is a sedimentary stone, Granite is a metamorphic stone and Marble is igneous stone, can give you some idea how these stones measure against each other in hardness.Alright, sedimentary stone is laid down, layer on top of layer, until it compresses enough to create a stone. Then igneous stone is created by magma being cooled and becoming a solid stone. Metamorphic stone is changed--with pressure and heat, creating a metamorphosis to another stone entirely.Thinking how each of the stones, which do you think would be the softest, the hardest, then the one left would be between the two others.I would deduct that Limestone would probably be the softest, as it is layer upon layer--not really going through much change or pressure to become Limestone. Now, to figure out which of the two left over might be the hardest. I would suggest the stone which has gone through the most heat and pressure would be the hardest. The stone which qualifies as the most changed, would be the metamorphic rock, Granite. What you have left over, is the igneous rock, Marble. To check if that truly would be the middle hardness, it was created with heat, which would be more "processing" than just layered like Limestone, but wasn't as "processed" as heat AND pressure as Granite was. So it appears that Marble would fit between Limestone as the softest, and Granite as the hardest.Now you have deduced how to determine the order of hardness between Limestone, Marble and Granite.

What is the hardest rock between granite and diamond?
The harder rock is diamond
Which is the hardest rock diamond sand stone marble granite?
Diamond
What stone is the hardest stone?
Diamonds is not a stone it's crystal actually. But the hardest stone is granite stone.
What is the average Rockwell hardness for granite?
Granite has a Rockwell hardness of 7, making it one of the hardest rocks. Talc scores a 1 on the scale, being extremely soft, whereas a diamond is rated at 10, the hardest known mineral.
What is the best type of drill bit for granite?
The best type of drill bit for granite is a diamond-tipped drill bit. Diamond is one of the hardest materials and can effectively drill through the tough surface of granite.
Is diamond harder than gypsum?
Yes, diamond is harder than granite. Diamond is the hardest mineral known. And it is several times harder than granite.
How does granite compare in hardness to diamonds?
Granite is significantly softer than diamonds. On the Mohs scale of mineral hardness, granite scores around 6 to 7, while diamonds rank at a perfect 10, making them the hardest known natural material. This means that diamonds can easily scratch granite, but granite cannot scratch diamonds.
What is the hardest rock between granite and marble?
Granite is generally considered to be harder than marble. Granite is a very hard, durable rock composed mainly of quartz, feldspar, and mica, while marble is a softer rock primarily made of calcite. This difference in composition gives granite greater resistance to scratching and other forms of wear compared to marble.
Why is granite harder than marble?
Feldspar and quartz, with a hardness of 6 and 7 on the Mohs Scale respectively, are the minerals that give granite its abrasion resistance. Its hardness is due to the interlocking crystal structure as it cools from melt, making it among the hardest of rock types.
