Igneous (pp. 215, 218) (a) rocks are formed when molten rock cools and hardens.
The term (a) (p. 220) describes rocks that have crystals so small that you can’t see them with your eyes, and sometimes not even with a microscope.
Clasts (p. 223) (a) are fragments of rocks that fuse together to form a larger rock.
Sedimentary (pp. 223–26) (a) rocks form from bonded rock fragments or fossils that have been transported by water or wind or from the precipitation of minerals from supersaturated water solutions.
Deposits of halite that penetrate vertically through rock strata are called salt (a) (p. 225).
Foliated (p. 230) (a) metamorphic rocks contain crystals in bands or parallel layers.
When limestone has undergone metamorphosis, it turns into (a) marble (p. 231).
In what ways do grains help scientists to identify rocks?
To what geologic event does the widespread existence of sedimentary rock testify?
Why are nonclastic sedimentary rocks also properly called chemical sedimentary rocks?
What three conditions are thought to cause metamorphism in rocks?
The law of conservation of matter implies that the earth’s matter can change in form but not in mass.
True
False
Most rocks are a mixture of two or more minerals.
True
False
Fossils are commonly found in granite.
True
False
Large crystals are always formed deep underground from molten rock that has cooled slowly.
True
False
Old-earth geologists believe that it took millions of years for layers of sedimentary rocks to form.
True
False
Some limestones are considered to be inorganic nonclastic sedimentary rocks while others are organic nonclastic or clastic sedimentary rocks.
True

Chalk is an organic sedimentary rock; that is, it formed from the remains of living organisms.
True
False
Cement and concrete are composed mainly of igneous rocks.
True
False
Some metamorphic rocks can be changed into other metamorphic rocks through metamorphism.
