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.
In order to form magma, what must happen to sedimentary, metamorphic or igneous rocks? For weathering & erosion to occur, what process will the rock usually go through first or at the same time? Can sedimentary rock form directly from metamorphic rock? Explain your answer. All rocks follow the same pathway through the rock cycle is a false statement. Why? How does granite (igneous) change into sandstone (sedimentary)? Define igneous rocks.
