Igneous rock composition C) mafic (basaltic)
however is dictated by the
amount of silica present in
the rock. Low silica
content results in a
_________________________ or dark
composition.
A) light
B) felsic (granitic)
C) mafic (basaltic)
D) intermediate (andesitic)
The intrusive and B) diorite and andesite
extrusive, intermediate
composition igneous are:
A) gabbro and basalt
B) diorite and andesite
C) granite and rhyolite
D) quartz and feldspar
,Igneous rock composition B) felsic
however is dictated by the
amount of silica present in
the rock. High silica
content will result in a
__________________________
composition.
A) dark
B) felsic
C) mafic
D) intermediate
The 3 major components D) A liquid, a solid, and a gaseous component
of magma include:
A) An intrusive, an
extrusive, and volatile
component
B) A mafic, a felsic, and an
intermediate component
C) An earth, a water, and a
wind component
D) A liquid , a solid, and a
gaseous component
The intrusive and C) granite and rhyolite
extrusive, felsic igneous
rocks are:
A) gabbro and basalt
B) diorite and andesite
C) granite and rhyolite
D) quartz and feldspar
,When magma solidifies B) intrusive, extrusive
(cools) it hardens to form
an igneous rock. Igneous
rocks like all other rocks
can be classified in terms
of their texture and
composition. Texture for
igneous rocks can be
classified as either
________________________ or
_________________________. Each of
these textures is
determined by how fast or
slow the magma cooled.
A) hot, cold
B) intrusive, extrusive
C) mafic, felsic
D) coarse-grained,
phaneritic
(T/F) Sills are igneous True
intrusive bodies that form
parallel to bedding.
True
False
The intrusive and A) gabbro and basalt
extrusive, mafic igneous
rocks are:
A) gabbro and basalt
B) diorite and andesite
C) granite and rhyolite
D) quartz and feldspar
, (T/F) Igneous rocks can True
have special textures. For
example, a porphyritic
texture has two different
minerals sizes which is
indicates two different
cooling rates.
True
False
____________________ involves the A) magma mixing
mixing of more and less
mafic magmas to produce
one of intermediate
composition
A) magma mixing
B) differentiation
C) assimilation
D) partial melting
