Crust
What is the definition of crust?
The outermost, solid, rigid layer we live on.
Where is the Upper Mantle located?
Below the crust
What is the lower mantle
The massive, deep part of the mantle.
What is the outer core
A swirling layer of molten metal.
What is the inner core?
The incredibly dense, super-hot ball at the very center.
True or False: The crust is broken up into pieces
True
The Upper Mantle is divided into two parts called the...
Lithosphere and the Asthenosphere
True or False: the lower mantle is solid
true
True or false: The outer core is solid
False
What state of matter is the inner core in?
solid
What are the broken pieces of crusts called?
Tectonic plates
What is the Lithosphere made of?
Crust and very top part of the upper mantle
What type of rock makes up the lower mantle?
Solid silicate rock
What elements is the outer core primarily composed of?
iron and nickel
What elements make up the inner core?
Iron and Nickel
Which is thicker: Oceanic or Continental crust?
Continental crust
What is the texture of the Asthenosphere?
solid, but plastic and capable of flowing very slowly over millions of years
Which elements can also be found in the outer core (other than iron and nickel)
Oxygen and Sulfur
How big is the inner core compared to the moon?
Which is denser: Oceanic or Continental crust?
Oceanic
What type of rock is the upper mantle made of?
Solid rock, but richer in iron and magnesium than the crust.
How thick is the outer core
From 2,900 km to ~5,150 km deep.
Why is the inner core solid?
immense pressure forces the atoms into a solid state.
