The plate tectonics that determine the shape of our continents may have originated from a huge impact billions of years ago. This huge collision with the Earth, thought to have occurred around 4.5 ...

The Earth's plates jostle about in fits and starts that are punctuated with earthquakes and volcanic eruptions. 4 min read There are a few handfuls of major plates and dozens of smaller, or minor, ...

We often affiliate plate tectonics with earthquakes, as we are all taught in school that the shifting of plates leads to big shakes. But plate tectonics serve a far more important job to the planet ...

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 ...

Map of the Earth showing tectonic plates. Early Earth likely had no plate tectonics, but a solid outer crust with no tectonic activity covered the entire planet. After being broken up by convection ...

Earth is special in that it has two things that other terrestrial planets don’t: an abundance of internal heat, from when our planet was molten rock, and liquid water. To understand why our planet is ...

Earth’s crust may have gone on the move roughly 3.8 billion years ago. “Earth is actually quite distinct to other planets, in that it has plate tectonics,” says study coauthor Nadja Drabon, a ...

A map of gravity variations on the Earth's seafloor, which mostly correspond to underwater ridges and the edges of Earth's tectonic plates. NASA Earth Observatory Plate tectonics may not be a ...

It is common knowledge that the Earth's rigid upper layer called lithosphere is composed of moving plates. But just what mechanism first set plate tectonics into motion still remains a mystery.

One of Earth’s defining features is its plate tectonics, a phenomenon that shapes the planet’s surface and creates some of its most catastrophic events, like earthquakes, tsunamis, and volcanic ...

Stephen has degrees in science (Physics major) and arts (English Literature and the History and Philosophy of Science), as well as a Graduate Diploma in Science Communication. Stephen has degrees in ...
