10 1st MQA Flashcards
Tectonic plates collide or move together
–> <–
Convergent plate
They seperate and move away of another <– –>
Divergent plate
Where two slide past horizontally
> /
/ <
Transform plate
Mostly found along the plate margins
Volcano Distribution
A geolist an navy submarine commander and part of his mission is to study the deepest part of the ocean floor
Harry Hess
Mountains that formed due to the movement place either apart or move each other
Mountain Ranges
Father of plate tectonics theory / Modern version of the continental drift theory
Alfred Wegener
Is the driving mechanism of plate movement
Convection Current
Solid Layer of earth
Lithosphere
Collision between oceanic and continental crust / In Three Types of Convergent Plate Boundaries
Oceanic Continental Converge
A ductile layer under the solid lithosphere
Asthenosphere
Both oceanic crust have the same density
Oceanic - Oceanic Convergence
Two continental crust move toward one another / Formation of mountains
Continental - Continental Convergence
The plates slide past horizontally to each other without destroying the lithospheric plate
Transform Plate Boundary
The origin where the earthquake occurs
Hypocenter / Focus
The point directly above the focus on earth
EpiCenter
Sweep the surface in a side to side
Love waves (L Waves)
Occurs on the lithosphere / Either love wave or rayliegh wave
Surface Waves
Shakes the ground in a up and down motion
Rayliegh waves (R waves)
An instrument that detects measure seismic waves
Seismograph
Quantative measure of an earthquake
Magnitude
Most Common Scale on an earthquake
Richter Scale
Massive rigid of rocks that form earth’s continents / Composed of granite
Continental Plates
