Layers of the Earth quest
What are the layers of the Earth?
Inner Core, Outer Core, (Lower) Mantle, Asthenosphere, Lithosphere, and Crust.
How is density related to the earths material placement?
Iron and nickel are denser than minerals and rock so the iron and nickel goes to the center so now the Inner Core and the Outer core.
Where does the convection in the Earth happen?
It happens in the Outer core, Mantle, and the Asthenosphere.
How thick is the Inner Core?
It is 1,200 km thick.
How thick is the Asthenosphere?
It is 100 km thick.
How thick is the Lithosphere?
It is 125 km thick.
How thick is the Outer Core?
It is 2,300 km thick.
How thick is the Mantle?
It is 2,675 km thick.
How thick is the Crust?
It is 5-75 km thick.
What is the consistency of the Outer Core?
It is completely liquid.
What is the consistency of the Asthenosphere?
It is gooey, not liquid or solid.
What is the consistency of the Mantle?
It is gooey, not liquid or solid.
What is density?
It is mass per volume or how much stuff in a space.
What is convection?
It is movement within a fluid due to heat.
What is the consistincy of the Inner Core?
It is solid from pressure.
What is the consistency of the Crust?
It is solid.
What is the consistency of the Lithosphere?
It is solid.
Who came up with the theory of Continental Drift?
It was Alfred Wegener.
What is the evidence for continental drift?
There are matching fossils in places of the earth that are very far apart. The continents also look kind of like puzzle pieces as well.vd
What are the Inner and Outer core made of?
They are made of iron and nickel.
What is the Crust, the Mantle, the Asthenosphere, and the Lithosphere made of?
They are made of rock and minerals.
