Continental Drift: The groundbreaking theory of moving continents

By Becky Oskin published

Continental drift was Alfred Wegener's theory proposing continents move position on the Earth's surface.

Earth has a 'pulse' of 27.5 million years

By Yasemin Saplakoglu published

Most major geological events in Earth's recent history have clustered in 27.5-million-year intervals — a pattern that scientists are now calling the "pulse of the Earth."

Plate tectonics is the means through which mountains are formed. Image shows rippled gray mountains, mostly treeless, beneath a cloud-studded blue sky. The Baird Mountains in Alaska’s Kobuk Valley National Park formed when two tectonic plates along a convergent boundary collided, causing solid rock to buckle and fold.

What is plate tectonics?

By Tiffany Means published

Blame plate tectonics for Earth’s mountains, earthquakes, volcanoes, and why its continents fit together like pieces of a giant jigsaw puzzle.

A microscopic view of a thin piece of polished rock from Jack hills. A gypsum plate on the microscope allowed scientists to see a rainbow spectrum of quartz. Rocks from Jack Hills are 99% quartz, and the remaining 1% includes precious zircons.

Iceland's Reykjanes peninsula has been shaken by more than 20,000 earthquakes this week. Scientists expect an imminent volcanic eruption.

Swarm of 20,000 earthquakes could make Iceland's volcanoes erupt

By Brandon Specktor published

A swarm of more than 20,000 earthquakes has rattled southern Iceland this week, and geologists suspect a volcanic eruption is on the way.

The supercontinent of Nuna-Rodinia broke up at the end of the Proterozoic era, ending a billion years of no new mountain formation, a new study says.

Earth's mountains disappeared for a billion years, and then life stopped evolving

By Brandon Specktor published

For a billion years Earth's mountains stopped growing, and may have starved the sea of nutrients, new research finds.
