Earth's crust once formed a dense "root" supporting Colombia's northern Sierra Nevada de Santa Marta mountains, but new research suggests this prop sank into the mantle millions of years ago.

Our planet has been asteroid-smashed, melted and eroded, enough that most of its original armor has been long buried. Except ...

Scientists have discovered two mountains which reach heights of around 620 miles (1,000km), dwarfing anything else found on ...

One idea is that the mountains are parts of the lower mantle that have been superheated due to their proximity with Earth's incandescent core. While the mantle can reach 3,700C (6,692F), this is ...

For about a billion years of Earth’s history, nearly all of the planet’s mountains may have stopped growing, but exactly why remains uncertain. Robb Kendrick, Nat Geo Image Collection SCIENCE ...

Gu also noted that it requires further investigation to assess whether the discovered habitable planet truly possesses conditions suitable for Earth-like life. The research is jointly conducted by the ...

Like Venus and Mars, Earth has mountains, valleys, and volcanoes. But unlike its rocky siblings, almost 70 percent of Earth's surface is covered in oceans of liquid water that average 2.5 miles deep.

KUNMING, June 3 (Xinhua) -- For centuries, the question of whether life exists beyond Earth has intrigued humanity, and now a joint discovery by Chinese and German scientists may offer a ...

For nearly a billion years during our planet's "middle age" (1.8 billion to 0.8 billion years ago), Earth's mountains literally stopped growing, while erosion wore down existing peaks to stumps ...

About 2,000 miles below the Earth’s surface, the planet’s rocky mantle meets the molten, metallic outer core. Previously, a possible ancient ocean floor on the core-mantle boundary had only ...
