The melting point range of a substance is the temperature range from which the first crystal starts to melt, to the temperature at which the last crystal finishes melting. Key fact An impure substance ...

Beneath the ocean, massive tectonic plates collide and grind against one another, which drives one below the other. This powerful collision, called subduction, is responsible for forming volcanic arcs ...

Hold on, hold on! We may have a new world record here. Researchers from Brown University may have found a substance with a melting point that beats out the previous record by a few hundred degrees.

A new study changes our understanding of how volcanic arc lavas are formed, and may have implications for the study of earthquakes and the risks of volcanic eruption. Beneath the ocean, massive ...
