Taxonomy is the science of classifying organisms. The system currently used by taxonomists is called the Linnaean taxonomic system, in honor of Swedish biologist Carolus Linnaeus (1707 â 1778). The Linnaean system breaks down organisms into seven major divisions, called taxa (singular: taxon).
Generally speaking, the wall measures about 23 to 26 feet tall. The fracture surface of the wall is ladder type with the base measuring about 7.1 yards wide and the top measuring 6.3 yards wide on average, which makes it firm and very unlikely to collapse.
So I will give you the official length. The Great Wall of China is much longer than what has been commonly accepted as fact. The length of the wall was previously thought to be 8850 kilometers or 5500 miles. The actual length, however, is 21,196.18 kilometers. How many miles long is the Great Wall of China? An unbelievable 13,170 miles.
