How did the layers form?

How did the layers form? The Earth’s layers were formed because of density.

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.

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.

What are the layers made of?

What are the layers made of? Inner Core: solid iron (Fe) and Nickel (Ni).

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

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.

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

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.

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.

What are the layers made of? Mantle:

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.

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.

What are the layers made of? Crust:

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

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

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)

Where is the lithosphere?

Where is the lithosphere? The lithosphere contains:

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

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

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.
