That is why I believe in 1 million years that South America and Africa will be far, far apart. I know this because of plate movement. In the Geochronology map it shows that when plates spread a part which is a divergent boundary, then as magma heats and cools, new sea floor is ...
The Pangaea timeline spans hundreds of millions of years. In the early Phanerozoic eon (541 million years ago to now), almost all of the continents were in the Southern Hemisphere, with Gondwana, the largest continent, spanning from the South Pole to the equator, according to a chapter in t...
Primitive moss-like plants could have triggered the cooling of the Earth some 470 million years ago, say researchers. A study published in Nature Geoscience may help explain why temperatures gradually began to fall, culminating in a series of "mini ice ages". Until now it had been thought tha...
And 20 million years ago, the San Andreas Fault was born. => 而在二千万年前,圣安地列斯断层诞生了。 It was the moving plates that crushed different types of rock together, just as here at Mussel Rock. => 就像在这里的贻贝岩一样,移动的板块把不同类型的岩石压碎在一起。
more than 200 million people, disproportionately those already vulnerable, poor and marginalized (intragenerational injustice), could be exposed to unprecedented mean annual temperatures41, and more than 500 million could be exposed to long-term sea-level rise (Fig.2andMethods). These numbers of peop...

The mission generated scientifically valuable dataset consisting of about 3.5 million points during approximately 2-year period [168]. CINEMA mission consists of four 3U CubeSats funded by NSF and Kyung Hee University in South Korea and developed in collaboration between University of California, ...
“will not lose or gain a second in 300 million years,” says Luigi Cacciapuoti, an ESA physicist who helped build and launch the device. (In 2022, China installeda potentially stabler clock on its space station, but the Chinese government has not publicly shared the c...
Earth’s oxygenation derives from the emergence of oxygenic photosynthesis; however, the GOE likely followed the initiation of this innovation by several hundred million years16. The reason for this apparent time lag remains a topic of considerable debate. Various hypotheses rely on the notion that ...
