One of the properties that is used to describe minerals is Mohs hardness scale which ranges
from values of 1-10. On that scale, which of the following is the hardest?
Quartz
All of the silicate minerals are based on the silicon-oxygen tetrahedran. These silicon-oxygen
tetrahedrons are arranged into how many different groups?
6
Which of the following are rocks that are formed from molten rock that cooled slowly under
ground?
intrusive igneous rock
A foliated rock is a sign that the rock was formed by
regional metamorphism
Plate tectonics do not really affect the rock cycle.
F
Which of the following occurs when lava heats up a rock and changes it?
contact metamorphism
Which of the following is the correct sequence of rock changes in the rock cycle?
none of the answers are correct
Sedimentary rocks can be produced from other sedimentary rocks.
T
Which of the following is not one of the three major types of rocks?
mafic
Different minerals crystallize at different temperatures even if they are composed of the same
compounds.
True
Which type of rock is created by sediment that is carried by river to the ocean or beach where it
is layered and produces a rock?
Sedimentary
Before the industrial revolution, rain water was not acidic.
F
Which types of rocks are fossils most likely to be found?
Chert
The breaking down of rock by wind, rain or ice is called _
(blank)
_ and is part of the process of
creating _
(blank)
_ rocks.
weathering, sedimentary
Which of the following types of metamorphism are caused by large scale pressure and heat?
regional metamorphism
Which of the following are NOT examples of extrusive igneous rocks?
Granite
Which of the following types of rock are least likely to have crystals that can seen or even form
at all?
Obsidian
The type of igneous rock produced depends on the composition of the magma that it is
produced from. If the magma were composed of 50% mafic materials and 50% felsic materials,
then the igneous rock produced is called
Diorite
What type of rock is most likely to form at subduction zones?
andesite
Muscovite and biotite are both minerals that are mica but differ in which property?
Color
CHAPTER 2
As hot mantle rock rises, it expands. As it expands it
cools and becomes more dense so it sinks. This contributes to the heat flow convection process.
Wegner correctly hypothesized that the continental plates pushed through the oceanic plates as
Pangea separated into the continents that we see today.
False
Two continental plates that are pulling apart such as the Rift Valley of Africa, are called
divergent boundry
The upper mantle has two different regions, the
asthenosphere (lower zone of the upper mantle) and part of the lithosphere (the top zone of the
upper mantle).
Which of the following is the Earth’s core composed of?
an iron-nickel alloy.

Continental plates are for the most part, made of
granite rock
The formation of the Aleutian Islands off the coast of Alaska, were caused by
two oceanic plates colliding with one another causing volcanism.
The Himalayan mountains are caused by
Two continental plates crashing into one another.
