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
