1. Some rocks that already exist can be changed by high changefossilshighigneousmarblemetamorphicpressuresandstonesedimentaryshaleslatetemperature and pressure into changefossilshighigneousmarblemetamorphicpressuresandstonesedimentaryshaleslatetemperature rocks.

2. The high changefossilshighigneousmarblemetamorphicpressuresandstonesedimentaryshaleslatetemperature is caused by the weight of all the rock layers above.

3. The word metamorphic means changefossilshighigneousmarblemetamorphicpressuresandstonesedimentaryshaleslatetemperature in form and these rocks can be formed either soft changefossilshighigneousmarblemetamorphicpressuresandstonesedimentaryshaleslatetemperature rocks or from the usually harder changefossilshighigneousmarblemetamorphicpressuresandstonesedimentaryshaleslatetemperature rocks.

4. Some examples of metamorphic rocks are:
(a) the sedimentary rocks limestone and chalk can be changed into the very hard rock changefossilshighigneousmarblemetamorphicpressuresandstonesedimentaryshaleslatetemperature,
(b) the sedimentary rock changefossilshighigneousmarblemetamorphicpressuresandstonesedimentaryshaleslatetemperature is changed into the highly layered changefossilshighigneousmarblemetamorphicpressuresandstonesedimentaryshaleslatetemperature used for roofing,
(c) the sedimentary rock changefossilshighigneousmarblemetamorphicpressuresandstonesedimentaryshaleslatetemperature is changed into white 'sugary looking' quartzite.

5a. You do not usually find changefossilshighigneousmarblemetamorphicpressuresandstonesedimentaryshaleslatetemperature in metamorphic rock even they were in the original sedimentary rock because the changefossilshighigneousmarblemetamorphicpressuresandstonesedimentaryshaleslatetemperature temperature and pressure will destroy them.
