The Earth's outer layer is made up of a series of moving, interacting plates whose motion at the surface generates earthquakes, creates volcanoes and builds mountains. Geoscientists have long sought ...
A geologist has revealed intriguing insights into the volcanic activity on Mars. He proposes that Mars has significantly more diverse volcanism than previously realized, driven by an early form of ...
Why is Christian Science in our name? Our name is about honesty. The Monitor is owned by The Christian Science Church, and we’ve always been transparent about that. The Church publishes the Monitor ...
The Earth's mantle might not always move along in lockstep with the overlying tectonic crust—as set out in science textbooks for decades—but may instead behave differently. This is the conclusion of ...
Meghan Bartels is a science journalist based in New York City who covers the science happening on the surface of Earth. She can be reached via email. Let's get one thing out of the way: The ...
At subduction zones, the force of gravity drags dense tectonic plates beneath other, more buoyant plates. As the plates slide past one another, stress builds and is eventually released in the largest ...
It is all thanks to subduction, the process of recycling that sends old oceanic crust back into the mantle. For the Cascades, this is subduction of three very small tectonic plates: the Juan de Fuca, ...
Geography textbooks describe the Earth's mantle beneath its plates as a well-mixed viscous rock that moves along with those plates like a conveyor belt. But that idea, first set out some 100 years ago ...
The theory of plate tectonics is strikingly recent in scientific history, which was widely accepted in the early 1960's. Now, scientists have discovered an alternative style to plate tectonics and ...
