Nobody knew what they are, and whether they are only a temporary phenomenon, or if they have been sitting there for millions ...

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 ...

These are plate boundaries where two plates are either slipping past each other in opposite directions or at different rates in the same direction. The plates do not move past each other smoothly.

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

The new work suggests that the edge of the dichotomy was eroded back by hundreds of kilometers during the time when an ocean ...

Susan Schwartz, a professor at the University of California, Santa Cruz, will present a lecture titled "Anatomy of a Megathrust Plate Boundary Through the Earthquake Cycle" at 11 a.m. on Thursday, ...

We can have lots of bubbles of different sizes for different aspects of our lives. Importantly, upholding these boundaries is all about what you do, not what others do. You can't force someone to ...

or have a different composition, than the surrounding rocks. This finding challenges our current understanding of the Earth's plate tectonics—and presents the researchers with a major mystery.

Tectonic plates interact with each other in different ways. They can move apart (divergence), come together (convergence), or slide past each other (transformation). These interactions create ...

Part VII of our series on the history of Stoner Hill examines how the Home Owners Loan Corporation (HOLC) and the Federal Housing Administration (FHA) redlined portions of Stoner Hill ...

Volcanoes and earthquakes are both natural phenomena driven by the dynamic processes that shape Earth’s interior and surface.
