Question and Answer
Samples and Techniques
The Three major types of rocks are
Igneous, Sedimentary and Extrusive.
Metamorphic
Cementation often occurs directly after
Earth materials are _____________ ?
This process forms what type of rock?
Which of the following would NOT be a major
process in the formation of sedimentary rock.
erosion
deposition
melting
compaction
Ripple marks likely indicate that the rock
formed……..
Metamorphic rocks that have a banded
appearance due to the alignment of
minerals are called foliated rocks.
Which rock is made up of the smallest
sediments?
Shale
Breccia
Sandstone
Conglomerate
A fine grained igneous rock forms…..
Deep within the Earth
From magma
As the result of slow cooling
As the result of quick cooling
The formation of igneous rock is powered
by?
If a rock has a porhyrtic texture, what can
we conclude about the rock?
Minerals that crystallize from magma do
not form at the same rate or same
time. These rocks usually have larger
crystals surrounded by much smaller
crystals.
How could you easily distinguish a black
and white gneiss from a similar colored
granite?
Foliated = bands or layers
Marble is an example of a
foliated metamorphic rock
nonfoliated sedimentary rock
nonfoliated metamorphic rock
intrusive igneous rock
Which of the following is a fine-grained,
light-colored extrusive igneous rock?
Rhyolite
Granite
Limestone
Schist
Igneous rocks are classified by
composition and age.
composition and texture.
texture and size.
texture and presence of fossils.
What are the main agents of metamorphism?
compaction, cementation, and heat
heat, pressure, and hydrothermal solutions
heat, pressure, and erosion
heat, weathering, and erosion
Which of the following is NOT an example
of an igneous rock?
granite
basalt
rhyolite
sandstone
A(n) __________is any solid mass of mineral or
mineral-like matter that occurs naturally as
part of Earth.
Most rocks, such as granite, occur as a solid
mixture of _____________?
This produces low-grade metamorphism?
This occurs during mountain building?
Much of the upper mantle is thought to be
made of granite.
Ultramafic
