1) c)small mineral crystals
quickly cooling the molten material will result in rocks with small mineral grains. rocks that form as the result of different cooling rates will have both large and small mineral grains.
2) c)both of these
the crystals that are formed in intrusive rocks are visible to our naked eye which gives them a coarse grain compared to extrusive rocks.extrusive rocks have a fine-grained texture because the mineral crystals present within the rock are very small.granite is the intrusive rock that contains the high concentration of silica in the form of its quartz crystals. rhyolite is the extrusive counterpart of granite due to its high silica.
3) b)earth surface
the large crystals are the evidence to cool from molten rock that occurs at the earth surface.
4) a)partial melting
magma is produced by partial melting of subducted oceanic crust.
