Learning goals
- Explain how thermal convection in the asthenosphere drives lithospheric plate movement
- Distinguish between convergent, divergent, and transform tectonic plate boundaries
- Identify major geological formations produced at plate boundaries including trenches, mid-ocean ridges, and volcanic arcs
Before you begin
Distinguish crust, mantle and core and recognize a simple layer model.

Teaching and response guide
- Model the target skill: explain how thermal convection in the asthenosphere drives lithospheric plate movement. Use the first task as a guided example before asking for an independent response.
- Check readiness first: Distinguish crust, mantle and core and recognize a simple layer model.
- Discuss an incorrect response using this distinction: Tectonic plates include crust and uppermost mantle; the mantle is mostly solid rock that deforms over time, not an ocean of liquid magma.
Watch for: Tectonic plates include crust and uppermost mantle; the mantle is mostly solid rock that deforms over time, not an ocean of liquid magma.
Check the answer criteria for each task. A supported explanation may have more than one acceptable response. These activities offer evidence to discuss; completing a sheet alone does not establish mastery.
