1. Big Idea 1.0- Processes within the Earth’s crust cause natural events

3. Inside the Earth  Which model do you think best describes the Earth??

4. Diagram of the Earth

5. Layers  1. Atmosphere- is found above the earth’s surface, where most human activity is  2. Crust- all of Earth’s features that we can see (mountains, valleys, plains, etc.) occur in this layer.  At the bottom of the ocean is where the crust is the thinnest- only 6 km thick!

6.  3. Mantle- upper part of the mantle is solid and similar to the crust (this and the crust form the lithosphere).  As you go deeper into the mantle the temperatures increase and rock starts to melt  4. Outer Core- temperature here are so high that the rock is completely liquid and is referred to as molten

7.  5. Inner Core- this layer is still very hot but it remains solid.  The weight of the upper layers press this core into an extremely hard ball. In fact it is sooo hard that it is impossible to drill through- sorry no digging your way to China 

8. The Crust  This is the layer that we interact with. This is where we get resources such as oil, iron, diamonds, uranium, coal, potash, etc from  It is made up of solid rock but (as you know) this rock can look very different depending on where you are

10. Assignment- for tomorrow  Draw the earth’s layers  You will need to research the following:  The depth of each layer (inner and outer core, mantle, asthenosphere, lithosphere, and crust)  The density, compostion and temperature of each layer

11.  Look around the room? How many things can you see that are made from natural resources?  Glass is made from sand  Steel from iron and other minerals  Concrete from sand and gravel  Bricks are made from clay

12.  Now you are going to go outside and with a partner(s) make a sketch and see how many things in that sketch are produced from earth materials  Are there any flower beds or grass? What do the plants grow in?  Is the outside of the school covered with material made from the Earth?  Is there pavement (made from sand, gravel and oil?)
