Plate Tectonics

Question 1

Plate boundaries

Answer 1

• Divergent (boundary between two plates that are moving apart or rifting)
• Convergent (boundaries between two plates that are colliding, one plate will generally subduct under another)
• Transform (boundary between two plates that are sliding past each other)

Question 2

Evidence for the theory of plate tectonics

Answer 2

• Theory that explains how major landforms are created as a result of Earth’s subterranean movements
• evidence includes fossils, glaciers, and complementary coastlines

Question 3

Relate the major earthquake and volcanic regions to plate tectonics

Answer 3

• Earthquakes occur along fault lines (cracks in Earth’s crust where tectonic plates meet)
• Most volcanoes form at the boundaries of Earth’s tectonic plates

Question 4

GPS positioning

Answer 4

GPS measures the size of an earthquake by examining the final amount that a station has been displaced in an event.
