1st QT Flashcards
What are the components of the earth
Atmosphere
Hydrosphere
Lithosphere
Biosphere
the gaseous layer
Atmosphere
the liquid layer
Hydrosphere
the solid outer layer (the foundation)
Lithosphere
the life layer (all three layers combined)
Biosphere
Branch of geophysics which is concerned with the study of earthquakes
Seismology
device that measures earthquakes
seismograph
Vibrations generated by earthquakes
Seismic waves
Two types of seismic waves
Body waves
Surface waves
Two types of body waves
P wave (fast, weak) S wave (slower stronger)
Two types of Surface waves
Love wave (vertical and horizontal) Rayleigh wave (side to side)
measures shaking in a certain location
Intensity
measures the energy released at the source of the earthquake
Magnitude
what are the two types of plates?
Oceanic
Continental
Oceanic x Continental converge =
oceanic trench
Oceanic x Oceanic converge =
volcanic islands (like the ph)
what are the types of plate boundaries?
Convergent
Divergent
convergent plates go…
toward each other
divergent plates go…
away from each other
Oceanic x Oceanic diverge =
Volcano
continental x continental diverge =
rift valleys + new seas
What are the layers of the earth
Crust
Mantle
Inner core
Outer core
