SIOUX CITY (KTIV) - Gather your supplies! In this episode we will use everyday materials to learn about the formation of volcanoes. Volcanoes are openings where lava, small rocks, and gas erupt from ...

A large formation of granite discovered below the lunar surface likely was formed from the cooling of molten lava that fed a volcano or volcanoes that erupted early in the Moon's history -- as long as ...

Mars may have released sulfur gases that trapped heat, shaped the climate, and created conditions for ancient life.

Some scientists think we can better understand volcanoes by learning how the gaseous vortexes emerge. By Carolyn Wilke Some volcanoes perform a rather subtle trick: blowing rings of vapor that waft ...

"Tidal heating plays an important role in the heating and orbital evolution of celestial bodies," said Alex Hayes, professor of astronomy. "It provides the warmth necessary to form and sustain ...

Volcanoes in India are a fascinating yet rare geological phenomenon. These natural formations result from the movement of molten rock beneath the Earth's crust. While some volcanoes in India remain ...

The magma that erupts from basaltic volcanoes in the middle of tectonic plates originates from within Earth's mantle — rather than from the outer crust — and is propelled upward by CO2, not water.

While volcanoes have brought profound changes to landscapes here on Earth, volcanic activity on other planets and moons has followed a different path. It's easy to imagine space volcanoes as even more ...

Each mineral in a volcanic deposit is like a microscopic thermometer that records magma chamber temperature over time.

The Cascade Volcanic Arc stretches from Northern California to southern British Columbia and contains more than a dozen volcanoes. The U.S. Geological Survey classifies 11 of them, including Mount ...
