Tectonic research finds that Earth has six continents not seven
Memorizing seven continents feels settled, like learning the alphabet. A new study argues the ground rules are less tidy.
The dance of the continents has been reshaping Earth for billions of years, creating the landscapes we walk on today. Scientists are unlocking secrets about how plate tectonics forged our modern world ...
Like a moth in a cocoon, the metamorphosis of Earth's crust from molten goop to solid land is hidden from view, leaving scientists to guess at how the eons-long process unfolds. Using nearly four ...
Our planet was born around 4.5 billion years ago. To understand this mind-bendingly long history, we need to study rocks and the minerals they are made of. The oldest rocks in Australia, which are ...
Continental clues: Modern continental rocks carry chemical signatures from the very start of our planet’s history, challenging current theories about plate tectonics. Researchers have made a new ...
