molten rock called plumes rise to form volcanoes in the planet's crust. This spot is called a hotspot, and it creates atype of volcano not associated with a plate boundary. Yellowstone has produced three calderatypes of volcanic explosions: The first happened 2.1 million years ago at Huckleberr...

Magma is hot, molten material that comes from within Earth's mantle or crust and is forced out as lava during volcanic eruptions. It typically contains silicates, suspended crystals and dissolved gases [source: Oxford Dictionary of Science]. Another common categorization, called the Volcano Explos...
Deep below the Earth's crust, molten rock rises and falls, driving the movement of tectonic plates on our planet's surface — and for some time, researchers have debated whether the moon also has a molten layer of rock sandwiched between its core and solid exterior. New evidence, based ...
ballistic boulders and molten rock, all of which occur regularly, can appear or change direction without warning. Indeed, technically everything between the volcano and the roads that run fromLa Fortunato Laguna de Arenal and El Castillo lie in a high-risk area – a guide and a young girl ...
In fact, the Earth's surface was a molten rock for perhaps the first 800 million years of the planet's existence, not exactly the best environment to call home [source: Waggoner]. After the Earth's surface cooled and solidified into continental plates, the first microorganisms appeared. ...
Molten Made by melting and casting the substance or metal of which the thing is formed; as, a molten image. Melt To change (a solid) to a liquid state especially by the application of heat. Molten Reduced to liquid form by heating; A mass of molten rock Melt To dissolve The tide melt...
