SOL 7
The student will investigate and understand geologic processes including plate
tectonics. Key concepts include: A. geologic processes and their resulting
features; and B. tectonic processes.
Objectives: 6.a.2 Differentiate between continental crust and oceanic crust according to
topography, density, and thickness.
6.a.3 Outline the evidence for the Plate Tectonics Theory to include continental drift and sea-floor
spreading (seafloor age, magnetic reversals, seismic profiles, laser-measured motion studies, fossil
evidence, rock types associated with particular tectonic environments).
6.a.4 Explain how the lithosphere is divided into plates that are in motion with respect to one
another (compression, tension, and shearing) because of convection currents in the mantle.
6.a.5 Describe and identify the features of the three plate boundaries: divergent (sea floor
spreading, mid-ocean ridges, rift valleys, fissure volcanoes and flood lavas), convergent (subduction
and continental collision, folded and thrust-faulted mountains, volcanoes, trenches and island arc
formation), and transform (strike-slip faults). Include information about Hot Spot activity.
6.a.9 Interpret a map to determine that large scale, high energy events of geologic activity
(earthquakes, volcanoes and mountain building) occur as a result of motion along plate boundaries.
6.a.10 Interpret the tectonic history of an area based on the range and type of rocks as shown on a
map paying special attention to the east and west coast of North America.
6.a.
Compare and contrast different types of current and ancient plate boundaries (i.e. Japan,
California, the Appalachian system, Iceland, Tonga and New Madrid, Missouri.)
