HS-ESS1-5 2014 HS-ESS1-5: Evaluate evidence of the past and current movements of continental and oceanic crust and the theory of plate tectonics to explain the ages of crustal rocks. [Clarification Statement: Emphasis is on the ability of plate tectonics to explain the ages of crustal rocks. Examples include evidence of the ages oceanic crust increasing with distance from mid-ocean ridges (a result of plate spreading) and the ages of North American continental crust increasing with distance away from a central ancient core (a result of past plate interactions).] Tectonics: The theory of plate tectonics provides a framework for understanding the dynamic processes within and on Earth. 5.4.D Essential Questions 1. How does scientific understanding build over time? 2. Why has the Earth changed over time? 3. How do changes in one part of an Earth system affect other parts of the system? 4. Why have the Earth’s tectonic plates changed over time? Enduring Understandings 1. Science builds upon itself over time. 2. As new evidence arises and we acquire new understandings, old theories are revised or replaced by new ones. 3. Earth is a complex system of interacting rock, water, air, and life that has evolved over time. 4. Composition of the soils and the atmosphere provide the interfaces for changes in the composition of the Earth’s systems. 5. Theories governing the movement of lithospheric plates were developed over time through the analysis of Earth materials.

Plates are pushed apart at spreading zones and pulled down into the crust at subduction zones. Evidence from lava flows and ocean-floor rocks shows that Earth’s magnetic field reverses (North – South) over geologic time. 21st Century Life and Careers Cumulative Progress Indicators Explain the mechanisms for plate motions using earthquake data, mathematics, and conceptual models. 5.4.12.D.1 Calculate the average rate of seafloor spreading using archived geomagnetic-reversals data. 5.4.12.D.2 Common Core Standards Connections 9.3HL.1-.6 9.3ST.1-.6 ELA/Literacy: RST.11-12.1 RST.1112.8 WHST.9-12.1 WHST.9-12.2 SL.11-12.4 Mathematics: MP.2 MP.4 HSN-Q.A.1 HSN-Q.A.2 HSN-Q.A.3 HSA-SSE.A.1 HSA-CED.A.2 HSA-CED.A.4 HSFIF.B.5 HSS-ID.B.6 HS-ESS1-5 2014 Desired Results Open Ended/ EOC Response Items: 1. The diagram above shows a cross section of the edge of a continent. In this region a section of oceanic crust is gradually moving down under a section of continental crust. Explain how the mountain range near the seacoast on this continent was probably formed. 2. Why are the magnetic bands in the eastern Pacific Ocean so far apart compared to the magnetic bands along the Mid-Atlantic Ridge?
