Grade 8 SC.7.E.6.5 BENCHMARK SC.7.E.6.5 Reporting Category Earth and Space Science Standard Big Idea 6 Benchmark SC.7.E.6.5 Explore the scientific theory of plate tectonics by describing how the movement of Earth’s crustal plates causes both slow and rapid changes in Earth’s surface, including volcanic eruptions, earthquakes, and mountain building. (Also assesses SC.7.E.6.1 and SC.7.E.6.7.) Also Assesses SC.7.E.6.1 Describe the layers of the solid Ear th, including the lithosphere, the hot convecting mantle, and the dense metallic liquid and solid cores. Earth Structures SC.7.E.6.7 Recognize that heat flow and movement of material within Earth causes earthquakes and volcanic eruptions, and creates mountains and ocean basins. Benchmark Clarifications Students will describe the scientif ic theory of plate tectonics and/or how the movement of Earth’s crustal plates and the flow of heat and material cause various geologic events to occur. Students will identify and/or describe the la yers of Earth. Content Limits Items will not assess types of v olcanoes but may assess different causes of volcano formation. Items will not assess types of ear thquake waves. Items may assess density differences between layers of Earth but will not assess density differences as they relate to plate tectonics. Items assessing the layers of Earth are limited to the cr ust, the lithosphere, the hot convecting mantle, the outer (liquid) core, and the inner (solid) core. Stimulus Attributes None specified Response Attributes None specified Prior Knowledge This benchmark grouping is foundational. These concepts have not been introduced in the NGSSS prior to this g rade-level grouping. 56 | DRAFT FCAT 2.0 Science Test Item Specifications, Grade 8 Florida Department of Education Grade 8 100000314627 Sample Item 12 SC.7.E.6.5 SC.7.E.6.1 Interactions between layers of Earth cause convection currents to move crustal plates.
