Solid layer
of metal
inner core
Largest layer,
made up of hot, dense
rock
mantle
Thinnest layer,
made up of continental and
oceanic crust
crust
gasses and dust of
cloud was attracted by
gravitational energy
process of accretion
it created Earth’s molten core, which traps heat.
process of accretion
isotope
= same number _____
diff number ________
proton
neutron
A geological process that was formed, originated, and located below the surface of the Earth “Tectonic movements, Metamorphism, Magmatism”
endogenic processes
how is magma formed
partial melting
Usual temperature but the pressure is reduced
decompression melting
Happens when the rock is being moved toward the
surface, either at a “Mantle Plume”, or at a “Mantle
Convection Cell”
decompression melting
Rock is close to its melting point and coolant is
added to the rock, the melting temperature is
reduced and partial melting starts.
flux melting
As the magma moves upwards, it interacts
with the surrounding rock, initiating partial
melting onto other rocks.
flux melting
a magma that moves
up into a volcano without erupting
intrusion
an eruptions of magmatic
material that cause land formation on the
surface of the Earth
extrusion
Refers to all sorts of igneous geological activities taking place below the Earth’s surface
plutonism
