Terms in this set (26)
What are the three MAJOR layers of the earth?
Crust, Mantle and Core
What are the two parts of the core called?
Inner Core and Outer Core
the inner layer of Earth's core believed to be made of solid iron and nickel.
the outer layer of Earth's core made of melted, liquid metal
What elements make up the composition of the Core?
Iron and Nickel
Why is the earth's inner core solid but outer core liquid?
Even though both layers are extremely hot (and the core is the very hottest) the massive amounts of pressure on the inner core makes it solidify
the zone of earth beneath the crust and above the core. It is divided into the upper mantle and the lower mantle.
What elements form the composition of the Mantle?
Silicon, Oxygen, Iron, Magnesium
the rigid outer layer of Earth, made of the crust and the solid, uppermost part of the mantle
a region of Earth's interior immediately below the lithosphere where mantle rocks are hot enough and under enough pressure
to deform, change shape, and flow.
Which layer floats on which other layer?
Lithosphere on Asthenosphere
the outermost layer of Earth, composed of rock.
What happens to pressure as you go from crust towards the core?
What happens to temperature as you go from the core to the crust?
Which of earth's layers is the hottest?
Which of earth's layers is the coolest?
What state of matter is the earth's inner core in?
List the layers from least dense to most dense
Core, Mantle, Crust
List the layers from hottest to coolest
inner core, outer core, mantle, crust
List the layers from thickest to thinnest
mantle, outer core, inner core, crust
Where is the lithosphere?
The crust and the upper-most mantle
What are the two types of crust?
continental and oceanic
in the mantle-- hot mantle rises cool mantel sinks creating a circular motion
layers of the crust
plates, lithosphere, athstinosphere
thicker, less dense ( lighter ) made of granite
thinner, more dense ( heavier ) made of basalt
