Earth Science
Unit 3 – Plate Tectonics
Unit Objectives for Chapter 17 exam
Section 17.1 Drifting Continents



Describe the evidence that suggests that Earth’s continents may have
once been joined.
Relate the evidence of continental drift to movement of the continents
Explain why continental drift was not accepted when it was first
proposed.
Section 17.2 Seafloor Spreading



Summarize the evidence that led to the discovery of seafloor spreading
Explain the significance of magnetic patterns on the seafloor.
Explain the process of seafloor spreading.
Section 17.3 Theory of Plate Tectonics


Explain the theory of plate tectonics
Compare and contrast the three types of plate boundaries and the
features associated with each combination of oceanic and continental
plates.
Section 17.4 Causes of Plate Motions



Explain the process of convection
Summarize how convection in the mantle is related to the movements of
tectonic plates.
Compare and contrast the processes of ridge push and slab pull.
