The Earth’s Crust Doesn’t Stop – Scientists Discover Old and New Continents
Scientists have discovered an unexpected new continent hiding beneath Greenland. Zealandia, thought to be a candidate for Earth’s eighth continent, has been almost completely submerged by the sea. The new ocean could split Africa into two continents. Doggerland: Before it was inundated by a tsunami 8,000 years ago, this landmass connected Britain and continental Europe. Archaeologists and citizen scientists have discovered a number of artifacts from Doggerland over the years, including a deer bone with an arrowhead and a fragment of a human skull.
Global warming leads to a change in the speed of rotation of the Earth and a change in the length of the day
The melting of polar ice leads to a change in the planet’s rotation speed, which in turn affects the global calculation of time, a study from the University of California showed, reports the scientific journal Nature. Geophysicists from the University of California have found evidence that the slowing rotation of the Earth’s core, combined with the melting of the Antarctic and Greenland glaciers, will lead to the fact that in 2029, humanity will have to shorten, rather than increase, the length of the day for the first time.
