Earthquake and Faults Flashcards
(32 cards)
the outer most layer of the earth
Crust
this can be (35 - 70 km) thick
Continental crust (crust)
is thinner with thickness of about (5 to 10 km)
Oceanic crust (crust)
this is what the crust and the uppermost part of mantle form that is solid rocky sphere
lithosphere
this is what lithosphere thats brocken into segments callled
Lithosphere plates / tectonic plates
This theory is that these plates are moved by the hot plastic mantle beneath the lithosphere
Plate tectonics
2nd layer, its is the dense layer of hot semi solid and solit rock and mostly made up of ferromagnesium. (2900 km)
Mantle
3rd layer of the earth and the hottest part
Core
is a liquid layer about (2200 km) in thickness and made up of “dense iron”
outer core
is a solid layer 1250 km thickness and it is made of “iron and nickel”
inner core
is a path along the Pacific Ocean characterized by active volcanoes and frequent earthquakes.
Pacific ring of fire
a fracture or zone of fractures between two blocks of rock that moves with respect to another
Faults
3 types of Faults
Dip-slip fault/normal fault - Reverse fault - Transform fault
Origin of the earthquake
Focus/hypocenter
The point on earths surface, about the focus
Epicenter
pertains to the size and strength of the earthquake
Magnitude
is the observed effects of an earthquake
Intensity
numerals used to scale
1. Magnitude
2. Intensity
- Hindu-arabic numerals (1-9)
- roman numerals (I-X)
an insturement used to detect and record eathquakes and seismic waves
Seismograph
what is PHILVOLCS
Phillipine Institute of Volcanology and seismology
series of huge waves caused by an earthquake
tsunami
