Layers of the Earth

1. Layers of the Earth Brittany Vargo Kelly Swindler Kara Eckes

2. There are four layers of the earth: The crust The mantle The outer core The inner core

3. The Crust Outermost solid shell of planet Thinnest Layer 0-22 miles thick 0 degrees Celsius made up of rocks: igneous, metamorphic, sedimentary, basalt, diabase, and gabbro

4. The Mantle Second layer of the Earth Thickest layer 22-1790 miles thick 1000 degrees Celsius made up of plastic, magnesium, Iron, Aluminum, Silicon, and Oxygen

5. The Outer Core Third layer of the Earth 1790-3160 miles thick 3700 degrees Celsius made of liquid metals: Iron, Nickel and contains Sulfur

6. The Inner Core Innermost layer of Earth 3160- 3954 miles thick 4300 degrees Celsius made of solid Iron

7. Activity The point of the activity is to build an example of the layers of the Earth. Items needed: - Plastic bottle - Ruler - Marker - Candy

8. Step #1 In step one, we will build the inner core of the Earth. The inner core is equal to 1 inch. Measure from the bottom of the plastic bottle up and then mark at 1 inch. Fill the bottle with the candy up to the mark.

9. Step # 2 In step 2, we will build the outer core of the Earth. The outer core is equal to 1¾ inch. Measure from the top of the inner core layer up and then mark 1¾ inch. Fill the bottle with the candy up to the mark.

10. Step #3 In step 3, we will build the mantle layer of the Earth. The mantle is equal to 3 inches. Measure from the top of the outer core and then mark 3 inches. Fill the bottle with the candy up to the mark.

11. Step #4 In step 4, we will build the crust of the Earth. The crust is equal to ¼ inch. Measure from the top of the mantle layer and then mark ¼ inch. Fill the bottle with the candy up to the mark.

12. Activity Layers: Inner core= 1 inch Outer core= 1¾ inch Mantle= 3 inches Crust= ¼ inch
