(Clarification statement: Include the role of radioactive decay as a source of heat energy driving the process of convection, as well as the physical processes of slab pull and ridge push.) - **SG4.b**: Construct an explanation based on evidence that describes the mechanisms that create melt in the lithosphere in relationship to plate tectonics. (Clarification statement: The role of pressure release, added heat, and added water content should be studied relative to the plate tectonic locations where this melting occurs.) - **SG4.c**: Use models to predict and differentiate between the various types of folds and faults. (Clarification statement: Show the relationship between stress and strain relative to nature and type of deformation.) - **SG4.d**: Use models to communicate the differences between folded, fault-block, dome, plateau, and volcanic mountains to investigate their relationship to tectonic setting. - **SG4.e**: Analyze and interpret data to classify volcanoes using their interior/exterior features, magma composition, lithology, and plate tectonic setting - **SG4.f**: Analyze and interpret seismic data and assess risk of volcanic eruptions and earthquakes in Georgia and other areas in the United States. (Clarification statement: Include sources of seismic risk in Georgia from historic tectonic events (stored energy at “dormant” fault zones).) ## Georgia Milestones coverage No Georgia Milestones blueprint cites this standard.
