1. oneone ES-1 Objective: To identify the layers of Earth in order to describe the structure of Earth. Earth Note: What is it like inside the Earth? Drill: 1. Get a new Activity Sheet from the SET. 2. Complete Activity 1.

2. oneone ES-1 Crust Mantle Outer Core Inner Core

3. oneone ES-1 LET’S PRETEND THAT WE ARE TAKING A TRIP…TO THE CENTER OF THE EARTH!!!!! There are two main changes that will occur as we go deeper. What do you think they are? Discuss the question with your neighbor. Come up with a consensus? 1.The temperature increases. (Generated from the core.) 2.The pressure increases. (Due to weight of the Earth above)

4. oneone ES-1 Activity 3: Journey to the Center of the Earth Use the back of your paper to diagram the features of the Earth that you encounter as you travel deep into the Earth.

5. oneone ES-1 CRUST 1.Outermost layer 2.5 – 40 kilometers thick on average) 3.Oceanic crust is thinner (5 km) 4.Oceanic crust – more dense (basalt) 5.Continental crust is thicker (up to 70km) 6.Continental crust – less dense (granite)

6. oneone ES-1 Mohorovicic Discontinuity 1.The area separating the crust from the mantle.

7. oneone ES-1 Mantle 1.Nearly 3000 kilometers thick. 2.Most complicated layer 3.Several different parts 4.Uppermost is similar to the crust. 5.Just below is a plastic-like flowing layer. 6.Lower mantle - solid

8. oneone ES-1 Lithosphere 1.Composed of the crust and top part of the mantle. 2.Contains Earth’s moving plates 3.About 75 - 100 kilometers thick

9. oneone ES-1 Athenosphere 1.Just below the lithosphere 2.Plastic-like layer of the mantle, but still solid 3.Responsible for plate movement 4.Nearly 300 kilometers thick. 5.Convection occurs here.

10. oneone ES-1 Lower Mantle 1.Most of the mantle. 2.Solid 3.Extends to the core

11. oneone ES-1 Outer Core 1.About 2300 kilometers thick. 2.Liquid iron and nickel 3.May be responsible for Earth’s magnetic field

12. oneone ES-1 Inner Core 1.About 1200 kilometers thick. 2.Solid metallic layer – probably iron plus 3.Solid due to extreme pressure

13. oneone ES-1 Homework: 1.Review information 2.Identify Questions

14. oneone ES-1 Objective: To identify the layers of Earth in order to describe the structure of Earth. Earth Note: What is it like inside the Earth? Drill: 1. Open your log book. 2. Write 2 quiz questions with answers based on yesterday’s lesson.
