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.

Scientists have taken a journey back in time to unlock the mysteries of Earth’s early history, using tiny mineral crystals called zircons to study plate tectonics billions of years ago. The research ...

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.

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 ...

For millions of years, Earth’s moving plates have sculpted continents, carved oceans, and built massive mountain ranges. Yet some of these giant structures vanished deep into the mantle, hidden from ...

The colossal movements of tectonic plates shape our world, influencing the composition of Earth’s atmosphere, the planet’s protective magnetic field and perhaps even the flourishing of life. Now ...

Far beneath the ocean's surface, where mountain belts rise and ancient oceanic crust lies hidden, a long-lost tectonic plate has been brought back into view. In one of Earth's most tectonically ...

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 ...
