How thick is a single pane glass window typically? I recently broke the window in my dorm. I was resting my foot on the window, and it just broke underneath. I measured the thickness of the broken window, and found it only to be an eighth inch. I feel almost like I should be the one complaining...

By Andrew Alden. Metamorphic rocks are the third great class of rocks. These are what happens when sedimentary and igneous rocks become changed, or metamorphosed (changed in form), by conditions underground. The four main agents that metamorphose rocks are heat, pressure, fluids and strain.
What kind of rock is formed when existing rocks are changed by pressure or heat? Changes in the structure, texture, or mineralogy of existing rocks will create a metamorphic rock. Metamorphism can result from the effects of heat and/or pressure, or from â¦ the addition of ions from heated fluids.
