Diamond is the second hardest material found in nature. It was always thought to be the hardest, but scientists have recently discovered a material called Ionsdaleite which is 58% harder than Diamond.
The complete subject is "A natural resource" and the complete predicate is "is a material found in nature that is useful or necessary to living things". The simple subject is "resource" and the simple predicate is "is".
No, the hardest material known is diamond. Edit: Actually, diamond is only the hardest material which occurs naturally in macroscopic crystalline form. While the lonsdaleite found in meteorite craters has a Mohs hardness of about 7-8 (as opposed to diamond's 10), this is due to impurities and imperfections. It has been calculated that a pure lonsdaleite crystal would be 58% harder than diamond. Similarly, a crystal of wurtzite boron nitride would also be harder than diamond, although a method of producing such crystals is still to be found.
Enamel is the hardest tissue among animal tissues. It is found on the outer layer of teeth and is made up of mostly inorganic material, specifically hydroxyapatite crystals. Enamel is designed to protect teeth from wear and tear during chewing and other activities.
Teflon is a synthetic material made from compounds like polytetrafluoroethylene (PTFE). It is not found in nature and is produced through chemical processes.
One of the hardest plants to find is the Ghost Orchid (Dendrophylax lindenii), known for its elusive nature and preference for remote, swampy habitats. It is rare and only found in specific regions like Florida, Cuba, and the Bahamas. Its intricate flowers and cryptic coloration make it particularly difficult to spot in the wild.
Hardest material ever FOUND so far is still diamond because it's produced by nature. Nano-materials are proven to be harder than any diamond but since it's man made it can not be "found". It's engineered. So the question for this nano variants should be - how hard do you need it to be ?
The hardest material known to man is currently called lonsdaleite (a carbon form), which is approx. 58 % harder than a diamond and then there is wurtzite boron nitride which is about 18% harder than diamond. Both occur in nature just like diamonds.
Water.
Kryptonite is not found anywhere at all because it's a fictional material.
Hardness is the resistance of a gem to scratching and abrasion. It is one of the key qualities of a gemstone. Diamond is the hardest gemstone. The second hardest gemstone is corundum (ruby and sapphire).
The hardest material in the world is Wurtzite, it is very much same as that of a diamond but is more complex than diamond and thus makes it stronger than diamond. Wurtzite boron nitride becomes 80% stronger after the re-orientation process, and this makes it the hardest substance found on earth.
One of the hardest substances found in nature is the diamond. One of the strongest man made materials is called graphene.

False. Plastic is a synthetic material created by humans and does not occur naturally in the environment. While plastic waste can be found in nature due to human activities, the material itself is not a natural substance.
Diamond is often considered one of the hardest naturally occurring materials in the world. However, a synthetic material called aggregated diamond nanorods has been found to be even harder, making it one of the hardest solids known to date.
No, nylon is a synthetic polymer made from petroleum products. It is not found in nature and is produced through chemical processes in laboratories or factories.
