Lithosphere
the solid, outer layer of the earth that consists of the crust and the rigid upper part of the mantle
Asthenosphere
The solid, plastic layer of the mantle beneath the lithosphere; made of mantle rock that flows very slowly, which allows tectonic plates to move on top of it
Crust
the outer layer of the Earth
Mantle
the layer of the earth between the crust and the core
Outer Core
a layer of molten iron and nickel that surrounds the inner core of Earth
Inner Core
solid, dense center of the Earth. Made of iron.
Convection Current
the movement of a fluid, caused by differences in temperature, that transfers heat from one part of the fluid to another
Seismic Waves
Waves produced by earthquakes that help us study the inner layers of Earth.
Continental Crust
Thicker, less dense crust
Oceanic Crust
thin, more dense than continental crust, subducting crust
Shape of Earth's Magnetic Field
One magnetic pole to the other
Elements in Crust
alluminum, silicon, oxygen
Density and Convection Currents
Less dense(warm) liquid rises; More dense(cold) liquid sinks
Elements in Mantle
magnesium, silicon
Elements in Outer Core
nickel, iron, sulfur
Element in Inner Core
iron
State of Matter of Crust and Lithosphere

State of Matter of Asthenosphere
liquidy solid
State of Matter of Outer Core

State of matter of Inner Core

What Part of Earth Creates the Magnetic Field?
Inner core
What creates Earth's Magnetic Field?
It's formed by the opposite spinning of the Inner and Outer core
How does Earth's Magnetic Field influence us?
It protects us from harmful radiation
Besides the magnetic field, what does the inner core create?
gravity
Why is the Inner Core solid when it's so hot?
There is so much pressure, that it can't become a liquid.
