Essential Question: How does Earth's composition change the landscape Essential Question: How does Earth's composition change the landscape? Investigation Question: How are Earth's layers formed? Investigation 1 Claim: The Earth's layers are formed in the geosphere due to intense heating from radioactive decay at the core and gradual cooling of the mantle moving towards the crust, which is made of the lithosphere and the asthenosphere. Terms: Geosphere, Crust, Mantle, Core, Lithosphere, Asthenosphere, radioactive decay, seismic waves
Sequence of Terms Geosphere Seismic Waves Core Mantle Crust Lithosphere Radioactive Decay Asthenosphere
How are Earth's layers formed? Evidence: Figure 1.1 Justification How does radioactive decay cause the layers of Earth's interior? Terms: Geosphere, Crust, Mantle, Core, radioactive decay
How are Earth's layers formed? Evidence Figure 1.2 Justification How do scientists use seismic waves to investigate the Earth's interior? Terms: Geosphere, Crust, Mantle, Core, seismic waves
How are Earth's layers formed? Evidence Figure 1.3 Justification Why is the Earth layered into the Crust, Mantle and Core? Terms: Geosphere, Crust, Mantle, Core
Investigation Question: How are Earth's layers formed? Claim: The Earth's layers are formed in the geosphere due to intense heating from radioactive decay at the core and gradual cooling of the mantle moving towards the crust, which is made of the lithosphere and the asthenosphere. Justification: The Earth’s layers were formed in the geosphere because… Evidence: Use the evidence presented (1.1 – 1.3) to justify the claim stated above.
