Seen from space, our planet has often been called a "blue marble." It's not, however, just the swirly white clouds that give Earth its marbled appearance. The continents: They are what complete the ...

EVER since Wegener published in 1915 his remarkable theory of the drift of the continents and the movement of the poles, most of us have viewed a map of the world with entirely different eyes, and it ...

The geological staying power of continents comes partly from their losing battle with the Earth's oceans over magnesium. Continents lose more than 20 percent of their initial mass to chemical ...

The continents may have first risen high above the oceans of the world about 3 billion years ago, researchers say. That's about a billion years earlier than geoscientists had suspected for the ...

Ever wanted to know what people think of Earth? Google Maps lets you leave reviews for pretty much anything you can search for — including whole continents and oceans. Credit: Google Maps The denizens ...

Geoscientists have solved an age-old mystery of oceanic volcanism and plate tectonics, explaining why some islands contain so much continental material despite their distance from continental plates.

Massive terrestrial planets, called “super-Earths,” are known to be common in Earth’s galaxy, the Milky Way. Now a Northwestern University astrophysicist and a University of Chicago geophysicist ...

THE wide appeal of Prof. Wegener's theory of the arrangement of ocean and continent is shown by, the issue of a third greatly revised edition and of this excellent English translation. His theory is ...

We have both continents and oceans on Earth — but it didn't have to be this way. And on most planets, it probably isn't, says astrophysicist... Seen from space, our planet has often been called a ...

Earth is estimated to be around 4.5 billion years old, with life first appearing around 3 billion years ago. To unravel this incredible history, scientists use a range of different techniques to ...
