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 ...

Emerging evidence suggests that plate tectonics, or the recycling of Earth's crust, may have begun much earlier than ...

A subduction zone near Cascadia is unraveling piece by piece. The process offers a rare glimpse into how tectonic plates die and form new geological boundaries. With unprecedented clarity, researchers ...

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 ...

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 ...

NORFOLK, Va. — Fault lines are fractures or breaks in the Earth's crust where tectonic plates move past each other, often resulting in earthquakes. These geological features are classified into three ...
