Past sea level has varied by somewhat more than a hundred metres. This is primarily due to the growth and decay of ice sheets (mostly in the northern hemisphere) with water evaporated from the sea. The Mediterranean Basin's gradual growth as the Neotethys basin, begun in the Jurassic, did not suddenly affect ocean levels. While the Mediterranean was forming during the past 100 million years, the average ocean level was generally 200 metres above current levels. However, the largest known example of marine flooding was when the Atlantic breached the Strait of Gibraltar at the end of the Messinian Salinity Crisis about 5.2
Pseudoscientific metrology 40 and 10 are not only fundamental to the Earth, the Moon and the Sun, but also to the human body and water. In the water-based Celsius temperature measurement system, which is directly linked to base-10 numeration, the average human body temperature is 36.6 degrees (according to Russian medicine), whereas the maximal density of water, Tristan says, is 4.0 degrees (whereas it is in fact 3.98 degrees ). More recently Butler and Knight claimed that, on a scale where the absolute zero is defined as being minus 1,000 degrees, water boils at the temperature of 366 degrees, an "utterly remarkable"
