Is the upper mantle solid? How is magma classified? Is the oceanic crust solid or liquid? Does magma contain minerals? Is a diamond an igneous rock? Is gabbro an igneous rock? Is a caldera a composite volcano? What is a magma chamber?
Is magma a liquid? How do scientists decide how large a magma chamber is? What causes magma to form? Is magma a solid? What is a volcanic arc? What type of volcano is Askja? Where does andesitic magma form? What type of volcano is White Island?
Magma is extremely hot liquid and semi-liquid rock locatedunder Earth's surface. Earth has a layered structure that consists of the inner core, outer core, mantle, and crust. Much of the planet's mantle consists of magma. This magma can push through holes or cracks in the crust, causing ...
They were also blown away that there was no transition from granite to basalt, a boundary geologists call "Conrad discontinuity," which was reasoned to exist based on results of seismic-reflection surveys. Another discovery was liquid water far deeper than they had previously thought could exist....
The mantle is made up of solid rock that can flow very slowly over long periods of time.The core is the innermost layer of the Earth. It is divided into two parts: the outer core and the inner core. The outer core is liquid and mainly composed of iron and nickel. The inner core ...
Iron ore and coke, a carbon-rich substance from heated coal, are melted into a liquid substance in a furnace and then blasted with oxygen to create molten steel. This material is cooled into ingots, large castings of steel for storing and transporting materials, that are shaped between rollers...
The thermodynamic treatment of chemical equilibria between different liquid phases in the magma or between the magma and the solid phases have similarities with ionic exchange equilibria in fused salts and slags. Therefore the characteristics and thermodynamics of fused salts are presented here. After a...
The geology of the Earth's surface is continually being shaped by volcanic activity. This natural process begins deep beneath the crust, when superheated magma (a liquid rock material made up of minerals and gases) rises toward the surface and erupts through cracks or vents. The molten rock re...
The slow crawl of molten rock down barren volcanoes, the diamond-spray of magma as asteroids collided with a liquid slag-heap earth, the distant nuclear reactors in the stars, but nothing that could be called a flame. Fire is the bright twin of terrestrial life. It’s been here as long...
The crust, mantle and inner core of the earth are all solid rock (or iron in the case of the core). The only large portion of the earth's interior that is liquid is the outer core, andlava does not come from there(again, if it did, it would be molten iron). ...
