the slower wave; that does not travel through liquids
how was the magnetic field formed
The inner core and outer core spinning creates a charge
the dense, metallic center of the Earth
Core
Solid; most dense
Inner core
earths frozen waters
cryosphere
what is on characteristic of a p-wave
faster waves ; that travel through liquids
Gravity & nebula
thick middle layer of Earth

what is another characteristic of an s-wave?
cannot travel through liquids; slowest wave
what is the importance of the magnetic field
It protects earth from some sun radiation and solar winds
the rigid outermost layer of Earth: includes the uppermost layer of Earth
Lithosphere
what is the densest layer
Core
The gases surrounding earth
atmosphere
what is another characteristic of a p- wave
faster; does not travel through liquids
Earths strength of gravity depends on what and what
mass and volume
the layer of melted, plastic rock in the upper mantle
Asthenosphere
HOW DID THE LAYERS FORM?
Gravity pulled the densest materials to the center
Earth's solid body, including rocks, soil, sediments
Geosphere
how do the waves help you understand the Structure of Earth.
They help us know the substances of the different layers because only p-waves travel through liquid
