How and why do the textures of volcanic rocks differ from the textures of plutonic rocks?
Plutonic rocks, or intrusive igneous rocks, form within the crust. Since it takes longer to
cool, larger crystals are formed and are coarsely grained. Volcanic rock
Why are highly deformed metamorphic rocks such a common part of the continental
crust, even under the craton far from the plate margins?
Why is creep so often overlooked as a process in an area? What signs might tip you off
that it is occurring?
What is the carbonate compensation depth and how does it relate to the location of calcareous
oozes and siliceous oozes?
This is the depth in the sea at which the rate of dissolution of carbonate equals the rate of
supply. If the sea bed is above the CCD

What is the principle of uniformitarianism, and why is it important in geology?
The principle of uniformitarianism is a dynamic principle that suggests the Earths geologic
processes behave the same now as it did in the past. From this, we
