What sedimentary rock goes through metamorphism to marble?
Limestone
How is marble metamorphic rock formed?
Marble is a metamorphic rock that forms when limestone is subjected to the heat and pressure of metamorphism. Under the conditions of metamorphism, the calcite in the limestone recrystallizes to form a rock that is a mass of interlocking calcite crystals.
How does a metamorphic rock melt?
The process of metamorphism does not melt the rocks, but instead transforms them into denser, more compact rocks. New minerals are created either by rearrangement of mineral components or by reactions with fluids that enter the rocks.
What are the potential parent rocks for marble?
Marble is a metamorphic rock form composed of coarse crystals from parent limestone or dolostone rocks. Pure marble is white and composed of the mineral calcite.
Is marble a hard or soft rock?
While marble is often known as a soft stone (relatively soft – it’s still rock hard!), granite is one of the hardest substances we know of. As it forms, atoms are forced into a regular structure which is very hard to break.
Which of the following rocks is transformed into marble?
Limestone is transformed into marble. When limestone is subjected to the heat and pressure of metamorphism, marble, a metamorphic rock, is formed.
What are the two types of metamorphic rocks?
There are two main types of metamorphic rocks: those that are foliated because they have formed in an environment with either directed pressure or shear stress, and those that are not foliated because they have formed in an environment without directed pressure or relatively near the surface with very little pressure …
Why are metamorphic rocks the hardest?
Answer: Metamorphic rocks are almost always harder than sedimentary because they have gone many processe . They are generally as hard and sometimes harder than igneous rocks. They form the roots of many mountain chains and are exposed to the surface after the softer outer layers of rocks are eroded away.
What is the strongest rock on Earth?
The strongest rock in the world is diabase, followed closely by other fine-grained igneous rocks and quartzite. Diabase is strongest in compression, tension, and shear stress. If mineral hardness is the determining factor of strength then diamond is technically the strongest rock in the world.
What rock is the softest?
talc
What is the hardest rock to break?
Igneous rocks are formed from molten rock called magma. They are mostly crystalline (made up of interlocking crystals) and usually very hard to break.
Are rocks harder than minerals?
It was created in 1812 by the German mineralogist Friedrich Mohs and is one of several definitions of hardness in materials science. Mohs based the scale on ten minerals that are all readily available. As the hardest known naturally occurring substance, diamond is at the top of the scale….Identifying Rocks and Minerals/Hardness.

What is the strongest mineral on Earth?
Diamond is the hardest known mineral, Mohs’ 10.
What is the hardest thing on earth?

What is the hardest material in the universe?
