A mineral can be identified by breaking it and then examining the directions it broke in. This test uses the mineral characteristic called
cleavage.
All of the formulas below represent minerals. Which one contains iron?
A. PbS
B. Fe3O4
C. SiO2
D. CaF2
An important key to understanding and reading a topographic map is the
contour lines.
Earthquakes are most likely to occur where
one crustal plate moves under another.
A boundary where two tectonic plates come together, or collide, is called a
convergent boundary.
The formation of metamorphic rocks depends on
1) the composition of the
parent rocks.
2) temperature.
3) pressure.
Radiocarbon dating of a sample relies on the
half-life of chemical elements.
Which accurately describes the relationship between earthquakes and volcanoes?
Earthquakes and volcanoes often are located where tectonic plates meet.
In a sedimentary sequence, the older layers are on the bottom and the younger layers are on the top. This is known as the principle of

superposition.
Geologists often use examples of processes happening in the present to interpret evidence of things that happened in the past. This geological approach is called

uniformitarianism.
Which are the two most abundant elements dissolved in seawater?
Na and Cl
Typically, sedimentary rocks are formed
from eroded materials that settle in layers.
Which is a way to determine if rock layers in different locations in the world came from the same time periods?
Match the fossils in the rock layers being studied.
When mud and water are combined, the result is
a mixture.
Igneous rocks are classified by where they are formed. Which type of igneous rock forms underground?
intrusive
The three types of plate boundaries on Earth are divergent, convergent, and transform fault. A divergent boundary is located at which location?
Mid-Atlantic Ridge
Because layers of sedimentary rock can be uplifted or tilted, geologists need a way other than using the principle of superposition to identify the relative age of rock layers. What is the most common method of identifying the relative age of rock layers?
fossil correlation

Carbon dating is a process used to determine the age of
organic remains.
