Why is water vapor the most important greenhouse gas? Why is dichloromethane a good solvent? Why does evaporation lower the temperature of a liquid? Why do superposition eyes occur? Why is the size of particulate matter important? Why is rubber an amorphous solid? What is the reason why hydro...
While welded tubes are forced together through methods such as heating and cooling and used for heavier, more rigid applications such as plumbing and gas transportation, seamless tubes are created through stretching and hollowing for more lightweight and thinner purposes such as bicycles and liquid tr...
It forms during explosive eruptions of gas-charged magma. It is ejected from the volcano in a sudden blast and cools so quickly that bubbles of gas are trapped within the amorphous glass.Tektites are pieces of black glass formed by an impact somewhere between Australia and Southeast Asia about...
this would be the case if the melt inclusions were trapped at ~ 800 bars, the depth of magma storage of Reunion picritic magmas (Famin et al. 2009), since this is higher than the 330 bars at which, according to D-COMPRESS, a model undegassed Reunion liquid begins to degas sign...
The location beneath the vent of a volcano where molten rock (magma) is stored prior to eruption. Also known as a magma storage zone or magma reservoir.
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 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...
Two-phase flow isa flow in which two different aggregate states of a substance or of two different substances are simultaneously present. The possible combinations include gaseous/liquid (see Gas content of fluid handled), gaseous/solid and liquid/solid (see Solids transport). ...
Muong Nong-type (MN) tektites are a layered type of tektite associated to the Australasian strewn field, the youngest (790 kyr) and largest on Earth. In some MN tektites, coesite is observed in association with relict quartz and silica glass within inclu
