Scientists discovered plate anomalies in Earth's mantle using seismic wave analysis. These mysterious structures challenge ...

SIOUX CITY (KTIV) - Gather your supplies! In this episode we will use everyday materials to learn about tectonic plates and fault lines. A subduction fault is when two plates have different densities.

Minerals suggest large blocks of Earth’s crust moved around as early as 3.2 billion years ago Modern plate tectonics may have gotten under way as early as 3.2 billion years ago, about 400 million ...

Researchers analyzing ancient deposits in Australia found evidence that Earth's layers started to get mixed up — a fingerprint of plate tectonics — about 1.3 billion years after the planet formed.

An enduring question in geology is when Earth's tectonic plates began pushing and pulling in a process that helped the planet evolve and shaped its continents into the ones that exist today. Some ...

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 ...

New finding contradicts previous assumptions about the role of mobile plate tectonics in the development of life on Earth. Moreover, the data suggests that 'when we're looking for exoplanets that ...

Earth's surface is a turbulent place. Mountains rise, continents merge and split, and earthquakes shake the ground. All of these processes result from plate tectonics, the movement of enormous chunks ...

Plate tectonics is the theory that Earth's outer layer is made up of plates, which have moved throughout Earth's history. The theory explains the how and why behind mountains, volcanoes, and ...

Occasionally, planet Earth will grab the headlines: Underwater volcanic eruptions send ash into the air, or earthquakes generate massive waves that send people running for safety as the rest of us ...
