1. Tuesday 5/17/11  The Earth has Layers Date Activity Page 5/17 Earth Has Layers 3 Song 5/17 Layers of Earth Assign.

2. Content Objective 1. We will identify several layers of Earth and learn a few characteristics of each.

3. Language Objectives 1. We will learn about Earth’s layers through a slide show, a song and a reading assignment.

4. Earth’s Layers Three main layers make Earth’s interior: the crust, the mantle, and core. Each layer has its own conditions and materials.

5. The Crust Under the Continents- Continental Under the Ocean- Oceanic

6. Oceanic Crust Three main layers make Earth’s interior: the crust, the mantle, and core. Each layer has its own conditions and materials. Made of basalt- heavy dense rock It is the crust under the oceans 5 km (3 mi) to 10 km (6 mi) thick

7. Three main layers make Earth’s interior: the crust, the mantle, and core. Each layer has its own conditions and materials. Continental Crust Granite is lighter and less dense Granite continents sit on top of basaltic crust

8. Three main layers make Earth’s interior: the crust, the mantle, and core. Each layer has its own conditions and materials. Mantle 5-40 kilometers below the surface Asthenosphere is the “soft” layer under the lithosphere Lithosphere is crust + uppermost mantle

9. Three main layers make Earth’s interior: the crust, the mantle, and core. Each layer has its own conditions and materials. Core Inner CoreOuter Core Solid only because of intense pressure Liquid, rotating around solid inner core

10. Three main layers make Earth’s interior: the crust, the mantle, and core. Each layer has its own conditions and materials.
