Boulders the size of footballs could help scientists predict the West Antarctic Ice Sheet’s (WAIS) contribution to sea-level rise according to new research published this week in Geology. Scientists…

Volcanoes are notoriously hard to study. All the action takes place deep inside, at enormous temperatures. So geophysicists make models, using what they know to develop theories about what they don’t…

FACT: The inner core of the earth is a sphere with a radius of about 1,200 km, made mostly of iron, which has different mechanical and magnetic properties based on temperature. MYSTERY: Elastic…

Using the genetic equivalent of an ancient thermometer, a team of scientists has determined that the Earth endured a massive cooling period between 500 million and 3.5 billion years ago. Reporting…

Africa and Europe get about 4 mm closer every year in a northeast convergence direction. The exact position and geometry of the boundary between the African and Eurasian plates is unknown, but it is…

The Rocky Mountains have warmed by 2 degrees Fahrenheit. The snowpack in the Sierras has dwindled by 20 percent and the temperatures there have heated up by 1.7 degrees Fahrenheit. All could lead to…

Most of the Earth’s listed active volcanoes are located at the borders between two tectonic plates, where upsurge of magma from the mantle is facilitated. When these magmatic uprisings occur at a…

Earthquakes occurring at the edges of tectonic plates can trigger events at a distance and much later in time, according to a team of researchers reporting in Nature. These doublet earthquakes may…

Since we can’t sample the deepest regions of the Earth, scientists watch the velocity of seismic waves as they travel through the planet to determine the composition and density of that material. A…

People love to find things on Mars. Sometimes it's a face, and sometimes it's a really happy face. Other times it's pyramids or even DNA. This time, it's Bigfoot. The Mars exploration rover, Spirit…
