Durability is a broadly defined term. Durability against stress, shock, temperature, radiation, small children and so on.
Taking just one form - durability in a corrosive environment, AKA seawater; consider high nickel alloy metals, stainless steel in a generic form, will last a log time.
Consider clothing - engineered fibers like Kevlar can last in use, over a wide temperature range, in abrasive environments. Not particularly comfortable but durable.
The task then is to first define Durable in what sense!
Lonsdaleite is a mineral made from carbon atoms similar to a diamond but arranged in a different shape. It is also called hexagonal diamond. Lonsdalite is 58 percent stronger than diamond, making it the hardest physical material on the Earth.
GEOLOGY
our planet; its people
The hardest substance that is naturally occurring is a diamond. However, there are harder substances that have been made by scientists in labs.
Primordial means it is the earlier form of its kind or dates from the start of a planet or universe. Primordial material is sometimes found on meteorites that fall to Earth.
There is not fifth planet on Earth, since Earth is a planet...
Diamond ( an allotrope of carbon) is the hardest material known.
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.
Diamond. a very hard material that is the hardest substance ever, or at least discover to be the hardest substance on EARTH THAT IS
No,it is certainly not, although it is one of the main contenders for "most dense substance on earth".
No, Obsidian is the sharpest material on earth. Diamond however, is the hardest.
Diamond is not a metal, it is a mineral: the hardest material on earth.
They are used to cut other material because diamonds are the hardest thing on Earth.
The earth is of the physical planet, the world is of the affairs of man
GEOLOGY
The Aztecs were a diverse group of people in terms of physical features. However, common characteristics included brown skin, dark hair, and in some cases, a medium to short stature. Some individuals may have had features indicative of their Mesoamerican ancestry, such as almond-shaped eyes and broad noses.
The Earth's layers contribute to the planet's physical characteristics by the types of rocks these layers produce. The rock formation of the Earth's surface define the physical characteristics of the planet.
It is here a great confusion ! The rhenium diboride (ReB2) is supposed to be the hardest material today - but this assumption also is not generally accepted/confirmed.
