Plate Tectonics Study Guide (Chapter 13 Lesson 1)
Challenge Date __________
Earth’s Interior (Movements of Earth’s Crust worksheet and Earth’s layers notes)
1. Describe the characteristics of Earth’s layers.
Layer
State of Matter
What is it made
(solid or liquid?)
of?
Distinguishing Features
Crust
Mantle
Outer Core
Inner Core
Which layer is thickest?
Thinnest?
As depth in Earth increases, what happens to each of these characteristics?
Temperature ____________; pressure ____________; density ____________.
Pangaea & Continental Drift (Movements of Earth’s Crust worksheet, Continental Drift &
Evidence notes)
2. Who proposed the idea of continental drift?
the supercontinent
He named
which means
called the surrounding ocean
and
, which means
3. Describe how each type of evidence supports the idea of continental drift.
Fit of coastlines
Matching mountains
Climate evidence (glacier deposits and coal)
Fossil evidence
Seafloor Spreading & Subduction (Ocean Floor Processes notes & lab)
4. What is seafloor spreading?
Where does new ocean crust form? Circle one: mid-ocean ridge
trench
As you get farther from a mid-ocean ridge, the age of the seafloor gets
What is subduction?
Where does subduction occur? Circle one: mid-ocean ridge
Where does oceanic crust go when it is subducted?
Be able to read a map that shows the ages of the Atlantic Ocean floor.
trench
Plate Tectonics (Plate Tectonics notes, Learning to Read Map of Tectonic Plates, Plate
Boundary notes, Identifying Plates & Plate Boundaries)
5. What is plate tectonics?
6. Describe the lithosphere and the asthenosphere.
lithosphere
asthenosphere
The Greek word “lithos” means
and “asthenos” means
7. Compare oceanic and continental crust. Which is thicker?
Which is denser?
8. Describe the different types of plate boundaries in terms of how plates move and features
that form (e.g. volcanoes, trenches, mid-ocean ridges, rift valleys, earthquakes, mountains).
Be able to recognize diagrams of each type.
Type of Boundary
Divergent
Direction of
Movement
Features that
Form
Diagram
Ocean to Continent
Convergent
Ocean to Ocean
Convergent
Continent to
Continent Convergent
Transform
9. Be able to read a map that of plates and plate boundaries. Given a location on the map,
identify the plates involved and the type of plate boundary between them. Identify the
features that form at those locations. For example:
Cascade Mountains
Japan
Iceland
San Andreas Fault
Mid-Indian Ridge
Cause of Plate Movement (Cause of Plate Movement notes and lab)
10. What causes plate movement? Why is there
convection in the asthenosphere? What is the
heat source?
