Units in this chapter
- Unit 2.1 · Earth's Internal Structure
I can describe Earth's layers by composition — crust, mantle, outer core, and inner core.
- Unit 2.2 · Plate Boundaries
I can identify divergent, convergent, and transform plate boundaries from a description or diagram.
- Unit 2.3 · Earthquakes & Volcanoes
I can distinguish the focus (hypocenter) of an earthquake from its epicenter.
- Unit 2.4 · Evidence for Continental Drift
I can describe Alfred Wegener's continental drift hypothesis and the supercontinent Pangaea.
- Unit 2.5 · Earthquake Evidence & Hazard Risk
I can use seismic observations to constrain an earthquake’s location.
