Exam # 1
The continental drift, plate boundary and
volcano worksheets are important guides to questions asked on the exam.
Students are expected to diagram all plate boundaries and locate an example of
each plate boundary on a world map.
Also, the USGS website:
http://pubs.usgs.gov/publications/text/dynamic.html
should be helpful with vocabulary and graphics.
The format of
the exam will include multiple choice, diagrams, perhaps a world map (to
identify plate boundaries) and 2 essay questions.
Exam #1:
origin of the Earth, plate boundaries, volcanic rocks, landforms, eruptive
styles
Chapter 1 (Introduction):
Questions: 1-10
All
figures
Chapter 2 (plate tectonics):
-
Structure of the Earth
-
Definition and explanation of the hypothesis of continental
drift
-
Evidence used to support this hypothesis
-
Definition and explanation of seafloor spreading
-
Evidence to support this hypothesis
-
Definition and explanation of the term plate tectonics
-
Evidence used to support this theory
-
The three types of plate boundaries in terms of types of
lithosphere involved, direction of plate movement and associated features (Be
able to draw a diagram of divergent and convergent plate boundaries)
-
Mechanisms thought to drive the tectonic plates
-
A general understanding of the Earth’s magnetic field in terms
of: how iron-rich minerals act as compasses; what did polar wandering explain
and how does the pattern produced on the seafloor help support seafloor
spreading.
-
Features, age and formation of the oceanic crust.
Questions: 1-10
Figures
help explain above statements
Chapter 6, Volcanoes:
-
How a volcano erupts
-
Why magma melts
-
Classification of lavas and volcanic rocks
-
Simplified Bowen’s Reaction series
-
Volcanic materials: lava, pyroclastic debris (ash to bombs)
-
Temperature, gas content, viscosity
-
Landforms
-
Eruptive styles
-
Caldera formation
Questions 1-14
Figures: 6.2; 6.4; 6.5;6.6; 6.8; 6.13; 6.14;
6.16; 6.16; 6.22;
6.25; 6.27; 6.28; 6.29; 6.30;6.34-5
Table 6.4; 6.5 (general not detail); 6.6
Chapter 7, volcanoes:
-
Understand
how lava type can be influenced by the type of setting but variations in
lava are common on continental crust
-
Give an
example of each tectonic setting (South America and the Nazca plate;
Yellowstone; Hawaii, etc.)
-
Name, describe and understand where
each volcanic hazard occurs
Questions: 1, 24,6,7, 8, 9,11
Figures: 7.1; 7.3; 7.4; 7.5; 7.6; 7.7; 7.8;
7.9-13; 7.14-23;7.25-29.
