Layers of the Earth
The only true liquid layer of the Earth
Outer Core
Although the mantle is considered a single layer of the Earth, it is broken into these three layers.
Lithosphere, Asthenosphere, and Mesosphere
The only layer in the Mantle that that is considered to have motion
Asthenosphere
Differentiation is the process where a new planet seporates in layers due to this.
Density
The least dense layer of the the Earth
The Crust
Between oceanic and continental crust, this type is thinner, denser, and primarily made of basalt
Oceanic Crust
This layer of the Earth is the largest layer and broken into 3 different layers
The Mantle
This layer of the mantle carries it's best friend the crust, on it's shoulders
Lithosphere
The Lithosphere State of matter
Solid, Brittle Rock
4.5 BYA, rock dust and meteors stick together to form the early Earth know as this theory
Mudball Earth
The chemical composition of this crust layer my be thinner, but has greater density
Oceanic crust
The inner core remains a solid state despite extreme temperatures because of this opposing physical force
Extreme Pressure
The outer most layer of the Earth
They say convection currents are the driving force of tectonic plates, so they must only occor in this layer
Asthenosphere
Your are able to find these in the only liquid layer in the Earth
Convection Currents
This is how Geologist calculate the Earths temperature through its layers
Geothermal Gradiant
Considering convection currents, when ultramafic rock is at the top of the astenosphere it does this,
Cools, becomes more dense, and sinks
Due to the liquid outer core moving around the solid inner core, this invisable force field is genorated to keep us safe from solar winds.
Eletromagnetic Field
This layer of the Earth is under so much presure not a single element of Fe or Ni can move
Inner Core
Only this layer of the mantle is considered to be in motion
Asthenosphere
The inner Core's state of matter
Solid
In early Earth's history, pressure was not the only source of heat to melt material. This thermal energy source unstable isotopes such as uranium-235
Radioactive Decay
This physical process caused heavier, dense molten metals like iron to sink toward Earth's center while lighter silicates rose to the surface.
Planetary Differentiation
These are the Earth's 6 layers in order from least dense to most dense.
Crust, Lithosphere, Asthenosphere, Mesosphere, Outer Core, Inner Core
The two types of crust that make up the crust
Oceanaic and Continental Crust
Although the Mesosphere is its official name, it is oftern refered to as one of these two names
Lower mantleand transition zone
Pressure keeps the Mesosphere in a solid state of matter even though it is this
Molten rock
During early Earth, volcanic eruptions relised this into the atmosphere
Carbon Dioxide
A geological process where one tectonic plate slides beneath another plate and sinks into the Earth's mantle at a convergent boundary
Subduction
The Earths gravitational pull is due to it's
