1. The Land
1. Describe and model the structure of the Earth including the terms lithosphere, asthenosphere, crust, mantle, outer/inner core.
2. Outline the plate tectonic model.
3. List and evaluate the evidences for the plate tectonic theory.
4. Describe the three types of plate boundaries.
5. Identify the type of plate boundary when looking at plate movement maps and images of natural disasters or landforms.
6. Explain how plate boundaries relate to seismic and volcanic activity.
7. Describe the impacts of earthquakes and volcanic eruptions on the Earth’s spheres.
Optional PBL Outcomes
P1. How important is evidence when considering the validity of a model?
P2. How has technology, like seismometers, have helped scientists understand geological activity?

1.1 Describe and model the structure of the Earth including the terms lithosphere, asthenosphere, crust, mantle, outer/inner core.
TASK 1.1
Complete the model of the structure of the Earth by researching the thickness and composition of each layer and adding to the flip book.
To the mantle layer, add the asthenosphere, the highly viscous, mechanically weak region of the upper mantle of the Earth. It lies below the lithosphere, at varying depths up to 700 km below the surface.
To the crust (below) and the mantle (above) layers, add the lithosphere, the solid, outer part of the Earth. The lithosphere includes the brittle upper portion of the mantle and also the crust.

3. List and evaluate the evidences for the plate tectonic theory.
