Essential Question: How does Earth's composition change the landscape Essential Question: How does Earth's composition change the landscape? Investigation Question: How do convection currents cause the movements within the lithosphere? Investigation 2 Claim: The uneven heating of Earth's layers causes the movement of tectonic plates through convection such as convergent (subduction) and divergent (seafloor spreading) boundaries that is either created or destroyed at a fault. Terms: Tectonic Plates, Divergent Boundaries, Convergent Boundaries, Seafloor Spreading, Subduction, Convection currents, faults

How do convection currents cause the movements within the lithosphere? Evidence: Figure 2.1 Justification How are convection currents formed? Terms: Convection currents

How do convection currents cause the movements within the lithosphere? Evidence Figure 2.2 Justification How do convection currents cause the creation of new lithosphere? Terms: Tectonic Plates, Divergent Boundaries, Seafloor Spreading, Convection currents, faults

How do convection currents cause the movements within the lithosphere? Evidence Figure 2.3 Justification How do convection currents cause the destruction of older lithosphere? Terms: Tectonic Plates, Convergent Boundaries, Subduction, Convection currents, faults

Investigation Question: How do convection currents cause the movements within the lithosphere? Claim: The uneven heating of Earth's layers causes the movement of tectonic plates through convection such as convergent (subduction) and divergent (seafloor spreading) boundaries that is either created or destroyed at a fault. Justification: The uneven heating of the Earth’s layers causes movement of tectonic plates because… Evidence: Use the evidence presented (2.1 – 2.3) to justify the claim stated above.
