3 How did the layers form?

4 The Earth’s layers were formed because of density.

5 How did the layers form? The Earth’s layers were formed because of density. – The heavier, more dense, materials were pulled in more by gravity.

6 How did the layers form? The Earth’s layers were formed because of density. – The heavier, more dense, materials were pulled in more by gravity. – Lighter, less dense, materials were not pulled in as much by gravity.

7 What are the layers made of?

8 Inner Core: solid iron (Fe) and Nickel (Ni).

9 What are the layers made of? Inner Core: solid iron (Fe) and Nickel (Ni). – Pressure is 48 to 52 million psi.

10 What are the layers made of? Inner Core: solid iron (Fe) and Nickel (Ni). – Pressure is 48 to 52 million psi. – Temperatures range from about 9,000 to 12,000 degrees Fahrenheit.

11 What are the layers made of? Outer core: liquid iron (Fe) and Nickel (Ni).

12 What are the layers made of? Outer core: liquid iron (Fe) and Nickel (Ni). – Temperatures range from about 4,400 to 6,100 degrees Fahrenheit.

13 What are the layers made of? Outer core: liquid iron (Fe) and Nickel (Ni). – Temperatures range from about 4,400 to 6,100 degrees Fahrenheit. – It is believed that the Earth’s magnetism is produced here.

14 What are the layers made of? Mantle:

15 What are the layers made of? Mantle: – Made of various minerals (Iron (Fe), Magnesium (Mg), Aluminum (Al), Silicon (Si), and Oxygen silicates ) that are in constant motion.

16 What are the layers made of? Mantle: – Made of various minerals (Iron (Fe), Magnesium (Mg), Aluminum (Al), Silicon (Si), and Oxygen silicates ) that are in constant motion. – Temperatures of up to 6,700 degrees Fahrenheit.

17 What are the layers made of? Crust:

18 What are the layers made of? Crust: The top layer of the Earth

19 What are the layers made of? Crust: The top layer of the Earth – The two types are continental and oceanic.

20 What are the layers made of? Crust: The top layer of the Earth – The two types are continental and oceanic. – Made of mostly Silicon (Si), Aluminum (Al), Calcium (Ca), Sodium (Na), and Potassium (K)

21 What are the layers made of? Crust: The top layer of the Earth – The two types are continental and oceanic. – Made of mostly Silicon (Si), Aluminum (Al), Calcium (Ca), Sodium (Na), and Potassium (K) – Fractures during earthquakes.

22 Where is the lithosphere?

23 The lithosphere contains:

24 Where is the lithosphere? The lithosphere contains: – The crust.

25 Where is the lithosphere? The lithosphere contains: – The crust. – A small layer of the upper mantle.

26 Where is the lithosphere? The lithosphere contains: – The crust. – A small layer of the upper mantle. Large chunks or plates that move gradually because they ride on hotter parts of the mantle.

27 Where is the lithosphere? The lithosphere contains: – The crust. – A small layer of the upper mantle. Large chunks or plates that move gradually because they ride on hotter parts of the mantle. – These “chunks” or plates make up the surface of the Earth.
