Endogenic processes Flashcards
Formed or occurring beneath the surface of
the Earth
Endogenic
Endo comes from the greek word
“Endon”
THE TWO FORCES BEHIND ENDOGENIC MOVEMENTS
Thermal and gravitational energy
Endo comes from the greek word “Endon” which means?
Within
Caused by radioactive decay and primoirdial heat
Thermal energy
2 types of diastrophism
Orogenic and epeirogenic
also known as the process of “mountain building”
orogenic
2 types of sudden movement?
Volcanoes and earthquakes
caused by the balance
between the frictional heating the Earth’s own mass and its angular momentum.
Gravitational energy
It refers to the deformation of the Earth’s crust
Diastrophism
also known as the process of “continental building”
Epeirogenic
A conical hill or mountain that has a
crater or vent through which the lava and other fragments are being erupted from the Earth’s crust
Volcanoes
temperature stays the same but the pressure decreases.
Decompression melting
volatiles comes into contact with hot-solid rock
Flux melting
Sites of flux melting?
Subduction zones
Sites of decompression melting?
Mid ocean ridges, volcanic hotpots, and rift valley
It is the ground shaking caused by the sudden movement of one block
of rock along the faults.
Earthquake
when a rock begins to melt, only certain minerals are melted
Partial melting
Site of partial melting
Mid ocean ridges, volcanic hotspots, rift valleys
