Researchers used small zircon crystals to unlock information about magmas and plate tectonic activity in early Earth. The research provides chemical evidence that plate tectonics was most likely ...

A subduction zone near Cascadia is unraveling piece by piece. The process offers a rare glimpse into how tectonic plates die ...

The diagram below shows the structure of the earth. In geography, taking a slice through a structure to see inside is called a cross section. Continental plates are usually quite thick (between 35 to ...

The first ruptures in early Earth’s skin formed because of the weakness of rock minerals merely a millimeter wide, two scientists propose. The small minerals’ behavior created boundaries defining ...

Plate tectonics is the theory used to explain the structure of the Earth’s crust and many of the associated phenomenon. The rigid lithosphere is split into 15 major plates that slowly move on top of ...

The Pacific and Australian plates collide and interact in complex ways around New Zealand. Electrical resistivity data reveal that subduction-zone fluids exert an important influence on deformation in ...

Plate tectonics might have gotten a fitful start on the early Earth. Today, the process of Earth’s crustal movement called plate tectonics dictates nearly everything about the planet’s appearance, ...

With tectonic plates bumping and grinding against each other, Earth is a pretty active planet. But when did this activity begin? A new study from Yale University claims to have found evidence that ...

Given that all of the Hawaiian Islands were created by volcanic activity, it is somewhat surprising that only one of the islands possesses any active volcanoes. Why did the volcanoes that built the ...
