What is the weakest rock?
Sedimentary rocksSedimentary rocks tend to be the ‘weakest’ of the three, as Igneous and Metamorphic rocks both undergo extreme pressures to form..
What are some fun facts about metamorphic rocks?
The word metamorphic literally means “changed form”. Slate, a metamorphic rock, can form from shale, clay or mudstone. The Taj Mahal in India is made entirely of different types of marble, a metamorphic rock. Serpentine is a type of metamorphic rock that originates as the igneous rock periodite.

What stone is the hardest?
DiamondDiamond is the hardest natural material in the world. However, it’s also brittle. Scientifically speaking, hardness measures the ability to resist scratching, nothing more. A gemstone’s overall wearability grade takes hardness into account.
Which rock is the strongest?
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’s harder than diamond?
boron nitrideThe structure of boron nitride in its wurtzite configuration is stronger than diamonds. Boron nitride can also be used to construct nanotubes, aerogels, and a wide variety of other fascinating applications.
How do you become a metamorphic rock?
Metamorphic rocks form when rocks are subjected to high heat, high pressure, hot mineral-rich fluids or, more commonly, some combination of these factors. Conditions like these are found deep within the Earth or where tectonic plates meet.

What was the first rock on Earth?
In 1999, the oldest known rock on Earth was dated to 4.031 ±0.003 billion years, and is part of the Acasta Gneiss of the Slave craton in northwestern Canada.
What is the rarest gem on earth?
MusgraviteMusgravite was discovered in 1967 and is arguably the rarest gemstone in the world. It was first discovered in Musgrave Ranges, Australia, and later found in Madagascar and Greenland. The first sizable gem-quality specimen was discovered in 1993.
What stone is better than a diamond?
White Sapphire is the clear winner in terms of a natural diamond alternative. Those choosing White Sapphire should expect white sparkle only as compared with the white and colored sparkle diamond offers.
Can you smash a diamond with a regular hammer?
To say something is “hard” is not the same as saying it is “strong”. As an example, you can scratch steel with a diamond, but you can easily shatter a diamond with a hammer. The diamond is hard, the hammer is strong. … This makes the diamond incredibly hard and is why it is able to scratch any other material.
Is Bedrock harder than diamond?
In our universe, diamond has a hardness of 10 on the Mohs scale. … Bedrock can be made from many different substances, with a hardness anywhere from 1 to 9. So even the hardest bedrock is still not as hard as diamond.
What happens if you melt a diamond?
At ~700 degrees Fahrenheit the diamond will start burning. This will produce Carbon Dioxide and change the structure so that it is no longer a diamond. As diamond is made of Carbon, it would revert back to that form while losing its mass to the production of CO2. This is due to the presence of Oxygen.
Which rock do you think would be the hardest and why?
Metamorphic rocks tend to be the hardest of the three types of rock, which are igneous, metamorphic, and sedimentary rocks.
Why metamorphic rocks are 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 rock is the softest?
talcThe name for talc, a sheer white mineral, is derived from the Greek word talq, which means “pure.” It is the softest rock on earth.
What can cut diamond?
Diamond manufacturers cut a groove in the diamond with a laser or saw, and then split the diamond with a steel blade. Sawing is the use of a diamond saw or laser to cut the diamond rough into separate pieces. Unlike cleaving, this step does not involve cleavage planes. This step gives diamonds their initial shape.
What is the strongest thing in the universe?
Summary: A team of scientists has calculated the strength of the material deep inside the crust of neutron stars and found it to be the strongest known material in the universe.
