Problem 1
Briefly describe Alfred Wegener's theory of continental drift. What evidence supported his ideas? How does Wegener's theory differ from the modern theory of plate tectonics?
Problem 2
Briefly describe the sea-floor spreading hypothesis and the evidence used to develop the hypothesis. How does this idea differ from Wegener's theory and the theory of plate tectonics?
Problem 3
Draw a cross-sectional view of Earth. List all the major layers and the thickness of each.
Problem 5
Describe and explain the important differences between the lithosphere and the asthenosphere.
Problem 6
What properties of the asthenosphere allow the lithospheric plates to glide over it?
Problem 7
Describe some important differences between the crust and the mantle.
Problem 8
Describe some important differences between oceanic crust and continental crust.
Problem 9
Explain how sea-floor spreading supports the modern theory of plate tectonics.
Problem 10
How is it possible for the solid rock of the mantle to flow and convert?
Problem 11
Summarize the important aspects of the plate tectonics theory.
