As we know, Pangea, a supercontinent that existed 335-175 million years ago, split into two different continents, forming Laurasia and Gondwana. Later, the two split apart to form all seven continents.
But scientists believe the continents will group together again in 250-300 million years from now and will become a single supercontinent called Pangaea Ultima.
A single-celled organism caused the first mass extinction.
Massachusetts Institute of Technology scientists suggest a theory explaining the mass extinction that wiped out almost 90% of all living creatures on Earth.A bacteria named Methanosarcina suddenly bloomed in the oceans 252 million years ago, triggering the only mass extinction of insects known to science. It also gave Archosaurs a unique opportunity to evolve.
Most of our planet always lies in the dark.
As we know, the World Ocean occupies 71% of our planet’s surface. The depth of the water exposed to sunlight is no more that 200 m, so the rest of the water is permanently in the dark. Therefore, most of our planet rests in the dark at any time of the day.
Neighboring states can have a 24-hour time difference.
Despite the fact that American Samoa is only 2,000 km away from the Line Islands that form part of Kiribati, the time difference between the two neighbors is 25 hours.
