Volcanic glass is the amorphous (uncrystallized) product of rapidly cooling magma. Like all types of glass, it is a state of matter intermediate between the closely packed, highly ordered array of a crystal and the highly disordered array of liquid. [1] Volcanic glass may refer to the interstitial material, or matrix, in an aphanitic (fine ...

Building codes in many parts of the world restrict the use of annealed glass in areas where there is a high risk of breakage and injury , for example in bathrooms , door panels, fire exits and at low heights in ...
The extensive use of such underground facilities brought about thousands of caves and pits in the Shephelah area, turning many hills into a sort of "Swiss cheese" full of holes.

In both cases, the moist and runaway greenhouse states the loss of oceans will turn the Earth into a primarily-desert world. The only water left on the planet would be in a few evaporating ponds scattered near the poles as well as huge salt flats around what was once the ocean floor, much like the Atacama Desert in Chile or Badwater Basin in ...
