D, DOK level 2 Constructed Response E.8.C.4 Score Rubric: Response addresses all parts of the question clearly and correctly. A. Convection is most responsible for plate movement. 3 points 2 points B. Volcanoes and earthquakes are found in similar regions or zones around Earth. There is a large concentration of these two events along the west coast of North and South America extending around the Pacific Ocean – Ring of Fire. Geologic events such as earthquakes and volcanoes are most often found near the edges of lithospheric plate boundaries, as here is where plate motion strains/stresses the rocks. C. Plate boundaries are crustal zones of weakness providing an easier path for magma from the mantle to head toward Earth’s surface. The center of lithospheric plates are more stable, and less likely to have crustal activity. Response addresses all parts of the question and includes only minor errors. Response does not address all parts of the question. 1 point Response is totally incorrect or no response provided. 0 points
