bob.
in one or two sentences, explain how the cooling rate of magma affects the texture of the igneous rock that is formed....
longer the magma cools the longer the mineral crystals grow. the less time the, the crystals will be smaller.

d. cross-bedding
chemical sedimentary rock forms when
a.magma cools and solidifies
b.minerals are twisted into a new arrangement
c.minerals crystallize from a solution
d.sand grains are cemented together
c.minerals crystallize from a solution
which of the following is a foliated metamorphic rock?
a.sandstone
b.gneiss
c.shale
d.basalt
b.gneiss
in no more than three sentences, explain the rock cycle.
magma, when it cools and solififies becomes igneous rock. igneous rock is sometimes expose at the earth's surface and become weathered. tiny fragments can be carried away and be desported in layers that eventually become sedimentary rock. this rock can be exposed to heat and pressure that can change it in different ways to turn into a metamorphic rock.
granite turns into _____ with heat and pressure... and which is igneous and metamorphic
gneiss-metamorphic
granite-igneous
limestone turns into _____ with heat and pressure... which is sedimentary and which is metamorpic?...limestone or _____
marble-metamorphic
limestone-sedimentary
