Volcanoes can also form where plates crash into each other. When one tectonic plate pushes beneath another, it's called subduction. The plate diving into Earth pulls down rocks and minerals full ...

Volcanoes are formed when magma (liquid rock) trapped underneath the Earth’s crust rises to the surface and escapes through cracks. The space for the magma to leave is very small and ...

The graphic below shows how the movement of the Earth's tectonic plates causes volcanoes to be formed, and what triggers a volcanic eruption.

The tallest volcano in Europe, Italy's Mount Etna, and the world's most active volcano, Kilauea in Hawaii, erupting again.

Video footage captured by Scott Malis during the volcano's 11th episode shows lava spewing out of Kilauea volcano and spinning into the air.

Igneous rocks form when magma cools underground or erupts at the surface as lava. The magma rises into the Earth’s crust, where it can get trapped underground or erupt from volcanoes as molten lava.

Through geochemical analyses, geoscientists at Heidelberg University have shown that the millimeter-sized sapphire grains found in the Eifel (Germany) formed in association with volcanism.

Yellowstone and Hawaiʻi. These systems a well known for producing large volumes of magma through time and leaving chains of ...
