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.
