Plate tectonics had arranged the world's continents into a single massive landmasses: Pangaea. Today I attempt to use my knowledge of geography to create a basic map of what this land might have ...

Plate tectonics give rise to Earth's mountain ranges, earthquakes and the long-term movement of continents, and may even have provided the right conditions for life on Earth. But as far as we know ...

The ocean plate was once the seafloor of Neotethys — an ocean that formed when the supercontinent Pangaea broke up into a ...

However, such an event is billions of years in our future. And before that could happen, Earth will likely be obliterated as our sun expands into a red giant and swallows the inner planets of the ...

Research on hidden structures deep within Earth’s mantle challenges theories about our planet’s middle layer and could ...

Though measuring animal intelligence is tricky, some animals show remarkable cognitive abilities that may rival our own.

Potential patches of Earth's ancient crust, sometimes called "sunken worlds," may have just been discovered deep within the mantle, thanks to a new way of mapping the inside of our planet.

Scientists have captured magnetic signatures from Earth's ocean tides in the finest detail yet. These faint signals, which certain satellites can detect when flying at very low orbits, may hold ...

Feb. 10, 2025 — Earth's inner core is undergoing structural transformation. Located 3,000 miles below the Earth's surface, the inner core is anchored by gravity within the molten liquid outer core.

Scientists have detected organic compounds and minerals necessary for life in the samples collected by the OSIRIS-REx mission from a near-Earth asteroid named Bennu.

Still, the nickname stuck. From Sept. 29 to Nov. 25, the object orbited on a horseshoe trajectory that brought it close to Earth before it receded away. During the object's visit, Teddy Kareta ...
