Make a model of Earth Using paper, make a pie-shaped piece to resemble the Earth. On the front, label the following: Inner core Outer core Mantle Crust Lithosphere
crust lithosphere asthenosphere Mantle Outer core Inner core
Open up your segment of the Earth and… • Mark the layers. • Label the state of matter of each layer. • What elements make up the core? • Label the thickness of each layer. • Label the temperature of each layer • using the numbers below. 12,000 F 9,000 F 4,500 F 100 F 6. Lightly color your model.
What is the center layer called?What state of matter is it?What is it made of? INNER CORE SOLID IRON AND NICKEL
Inner core Solid Nickel and iron 1,200 km 12,000 F
The next layer of the Earth after theinner core would be the……What state of matter is the outer core?What elements are in the outer core? OUTER CORE LIQUID Iron and Nickel
Outer core Liquid Nickel and iron 2,250 km 9,000 F
Why do you think the inner core is solid and the outer core is liquid? The core of our Earth is tremendously hot. It is believed to have a temperature of 7,000 degrees Celsius. Pressure keeps the inner core a solid, but allows the outer core to be a melted, liquid state.
Mantle solid and plastic 2,900 km 4,500 F
The mantle is a layer that is kind of like tar on a hot day. It flows, but very, very slowly. .
Asthenosphere plastic
The asthenosphere is just below the lithosphere. It is part of the mantle. The asthenosphere is solid rock that flows slowly, like hot asphalt or peanut butter.
The lithosphere includes the crust of the Earth and the upper mantle. . It is solid.
The outermost layer of our Earth is called the crust.
Lithosphere, which includes the crust solid 120 km 100 F
As the liquid iron and nickel in the core circulate, it creates a magnetic field.
What is this layer? State of matter? Inner core Solid
What is this layer? State of matter? Lithosphere Solid
What is this layer? State of matter? Mantle Plastic
What is this layer? State of matter? Outer core Liquid
