Review Chapter 1
The Earth: A Dynamic Planet
Draw two diagrams showing the folding and fault-block mountain building process.
In your own words explain how convection currents in the mantle move the plates of the Earth.
Use the following terms to answer the questions 3-14 below.
Collision plate boundary
Transverse plate boundary
Separation plate boundary
Continental Drift Theory
The southern continent after Pangea split apart. It became the continents of Africa, Antarctica, South America and the subcontinent of India.
The plate boundary where two plates are moving apart creating new crust and making the oceans spread.
This is molten rock on the surface of the Earth.
This is the name of the supercontinent 250 million years ago.
These are pieces of the crust that "float" and move because of the mantle's convection currents.
Molten rock under the surface of the Earth is called.
The northern continent after Pangea split. It was made of the continents of North America, Europe, and Asia.
A plate boundary in which the two plates crash into each other causing mountain building, earthquakes, and volcanic activity.
The idea that the Earth's plates are moving across the surface of the Earth.
A plate boundary in which the two plates are sliding in opposite directions.
The deepest area of the oceans. They are formed at a subduction zone.
What is the main material that the crust is made of?
What two metals make up the inner and outer core?
Name three pieces of evidence for the Continental Drift theory.
17-20. Label the four layers of the Earth and tell what main material makes up that layer.
