It's so big that all of the world's continents could fit into the Pacific basin. 42. Trees breathe in oxygen (Image credit: Getty Images) When we think about big life, whales and elephants come to mind. But try on this tree for size: The General Sherman giant sequoia is the largest...
As continents shift and clash, volcanoes erupt, and glaciers grow and recede, the Earth's crust is carved in numerous and fascinating ways, leaving a trail of geological mysteries behind. => 随着大陆的移动和冲突,火山爆发,冰川逐渐退缩,地壳以许多迷人的方式雕刻,留下了一些地质奥秘。 In this episo...
Nonetheless, the effects of the Moon's arrival, while never completely pulling the atmosphere away, caused huge tidal waves to sweep over its continents, volcanoes to erupt, earthquakes bringing mountains down and cyclones to rage across the planet. Millions of humanity's ape ancestors drowned or...
2). These initially include tectonic degassing of CO2, exposure of the continents and possible biotic enhancement of weathering from the Paleozoic-present due to plant colonisation (Fig. 2a–c). Most studies propose a decline in degassing rates over Earth’s history due to mantle cooling21. We...

Oscillating human population growth in all continents from 9000 to 3000 years ago is identified. These population cycles reveal synchronicity with cycles in climate stability, which in turn were possibly driven by variations in solar activity.
(motion) energy of Earth’s rotation. The Moon’s gravitational pull lifts a tidal bulge in the ocean; as Earth spins on its axis, this bulge remains essentially stationary. As Earth rotates, the tidal bulge runs into the coastlines of continents and islands, causing high tides. The force ...
During the past two billion years, for example, the total size of the continents has doubled. As the surface continually reshaped itself, over hundreds of millions of years, continents formed and broke up. The continents migrated across the surface, occasionally combining to fo 15、rm a ...

Despite, or rather because of, this simplicity, cratonic lithosphere provides a mean to gauge the interaction between continents and the ever changing mantle dynamics because regardless of the tectonic environment, it must remain undeformed to satisfy its stable definition. Here, we take advantage of...
