diamond is harder than rock and so are many minerals like silver and nickel rock is actually known as a silicate minerals silica and oxygen quartz is one of the hardest on of the silicate minerals and the most stable
Diamond.
Am existing rock can be made harder by recrystallization or additional cementation.
Granite is more expensive as it is made under the earth (metamorphic rock) and harder to extract than sandstone which is a sedimentary rock
geniss is stronger than granate because during metamorphic the granate change into geniss
You would normally think that an igneous rock would be harder to break. However, it completely depends on which igneous rock is being compared to which sedimentary rock, as their resistance to breakage is so varied. There are some igneous rocks (obsidian and pumice, for example) that would break much easier than some sedimentary rocks, such as chert or flint.
What is it called when softer rock weathers away and leaves harder rocks behind
Coal is considered to be a rock.
I am very sure that granite is much stronger and harder than sandstone.
Intrusive rocks are under pressure so they are usually harder.
Harder..One of the hardest things in the natural world.
The rocks are underground so intrusive rocks are under pressure so its harder.
Pedestal rocks are usually formed in desert, when wind erosion wears away softer rock under-laying a harder rock. The harder rock is eroded at a slower rate than the softer rock.
Impossible to say, not knowing the definition of plain regular rock. There are some rocks harder than obsidian, while many are softer.
it was harder than any rock he saw
Am existing rock can be made harder by recrystallization or additional cementation.
It's "You" by Chris Young.
That depends on WHAT rock or mineral we're talking about. Often, rocks are harder, though.
Since rock is harder than human flesh, it has the potential of pressing into us in uncomfortable ways if we lie on it - although a very smooth rock surface would not necessarily be uncomfortable.
