Workers in Building 602 made boosters through a process called melt casting, in which TNT is heated to a molten state and mixed with a more sensitive compound to increase its shock energy.

In contrast, chondrites retain primitive solar system dust as well as small molten droplets called chondrules.

Primary waves are the only kind that can travel through both solid rock and molten lava.

What drives the rumbling vibrations, called tremor, that occur when molten rock or gases travel upward through underground channels?

The discovery focuses on rare natural glass called tektites, which form when a meteorite hits Earth with enough force to melt the surface and fling molten material vast distances.
