Metamorphic rocks are dependent on the degree of melting, where complete melting "resets" the rock to magma and will then form igneous rocks when cooled.

Sedimentary rocks are primarily found in water and are formed by the clumping of materials, metamorphic have been literally morphed due to immense pressure and heat, and igneous rocks are volcanic ...

The volcanic rocks that the researchers collected at sites like Alaska’s Mount Shishaldin, shown in the distance, allowed them to probe the water content of the magma deep below the surface.

A fun way to learn the 3 rock types, how they're formed and how they fit into the overall rock cycle.

If the new age of these Canadian rocks is solid, they would be the first and only ones known to have survived Earth’s earliest, tumultuous time.

Scientists have worked out the consistency of the magma under the Yellowstone caldera using seismic waves — and the reservoir is filled with "mush" that doesn't pose an imminent eruption threat.

Magma-limestone interaction can trigger explosive volcanic eruptions and affect the global carbon cycle Date: August 7, 2016 Source: Uppsala Universitet Summary: New research shows what happens ...

Gather your supplies! In this episode we will use everyday materials to create a model of the rock cycle and explore the three different categories of rock.

Is Italy's 'supervolcano' filling with magma? Get the facts. Analysis of Campi Flegrei offers fresh insight into its activity cycle, but any rumors of impending doom would be greatly exaggerated.

From there, rocks "rain" back down into the 60-mile-deep magma ocean, which flows to the bright side to restart the cycle. However, this cycle is not as stable as the one on Earth, scientists said.
