Layers of the Earth Brittany Vargo Kelly Swindler Kara Eckes

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

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

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

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

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

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

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.

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.

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.

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.

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