Which rock is the hardest granite or chalk?
Chalk is a sedimentary rock composed primarily of Calcium Carbonate. Calcium carbonate is also the number one mineral at the Marble spec. Hardness of Chalk is around 3 Mohs. Granite stay at the number 7 at the Mohs scale and Granite is harder than Marble. Granite is mostly composed by feldspat (christal).
What are obelisks made of?
usally rock, such as marble or granite
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.
Would you expect acid rain to be greater problem in an area with marble bedrock or granite bedrock?
Marble as it is a carbonate rock which is soluble in acids.
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 type of rock is granite pumiceand marble?
Granite is an intrusive igneous rock. Pumice is an extrusive igneous rock. while, Marble is a (non-folliated) metamorphic rock.

What is the most durable igneous rock?
granite.granite
Is marble a volcanic rock?
No, it is a metamorphic rock. (metamorphosed limestone)

What isDifference between garnet and marble counter tops?
Marble is a metamorphic rock that was originally limestone, a sedimentary rock, and is composed primarily of the mineral calcite. Granite is an intrusive igneous rock composed mainly of feldspar, mica, and quartz. Marble is softer than granite because of these mineral composition differences and it will also react with weak acids such as vinegar. These properties make marble a good choice for a sculptor, but a bad choice for a kitchen countertop.
What kind of rock is the colosseum made of?
