Plate Tectonics Flashcards
tectonic plates moving TOWARD each other
convergent
tectonic plate SLIDING past one another
transform
cause of plate tectonics
convection currents
two types of plates
ocean
continental
plates below the ocean
ocean plates
plates below the continents
continental plates
products of divergent boudary
earthquakes fissure volcanoes linear lakes rift valleys mid oceanic ridges new ocean floor ridges
products of convergent boundary
volcanism
earthquakes
mountains
2 oceanic plates towards each other products
volcanoes island arc earthquakes trenches tsunamis
oceanic to continental plates towards each other
trench volcanoes volcanic arc earthquakes tsunami
2 continental plates towards each other products
mountain ranges
earthquakes
transform boudary products
faults
earthquakes
example of linear lakes
lake tanganyika
lake nyasa
example of ridges
mid atlantic ocean ridge
mid atlantic ocean ridge
divergence of the south american plate and the african plate
cause of red sea
arabian peninsula broken off from the african landmass
thin summits emerge beyond the surface of ocean, series of volanoes
island arc
example of trench
marianas trench in the pacific ocean
the denser oceanic plate dives beneath the continental plate
subduction process
subduction process
rock melts, rises then erupts
example of mountain ranges
himalayas in south asia
alps in europe
appalanchians in north america
example of fault
san andreas fault in california
bounde by the north american plate and the pacific plate
mountain formed in part by igneous activity associate with subduction of oceanic lithosphere beneath a continent
continental volcanic arc
a break in a rock along which moement has occured
fault
any break in a rock in which no significant movement has taken place
fracture
a concentration of heat in the manyle capable of creating magma
hot spot
a continuous mass of land with long width and height on the ocean floor
mid ocean ridge
a theory which suggests that earth’s crust is made up of plates that interact in various ways, thus producing earthquakes, mountains, volcanoes, and other geological features
plate tectonic
an event in which a slab of rock thrusts into the mantle
subduction
a depression in the sea floor produced by subduction process
trench
a chain of volcanoes that develop parallel to a trench
volcanic island arc
tectonic plates moving AWAY from each other
divergent
