However in my opinion some of the hardest and strongest rocks in the world are the quartzites found in the Witwatersrand in South Africa, Quartzite is a sandstone which has metamorphosed-that is it has been subject to high pressures and temperatures which have modified its structure.
The strongest living land creatures on Earth, measured by their power to weight ratio. 1. The strongest land creature on Earth (measured by power-to-weight ratio) is the oribatid mite, a group of tiny soil-dwelling things which can be found in their hundreds of thousands in your average square metre of dirt. It can resist a pull of 1,180 times its own weight - which is similar to a human pulling 82 tons.
