divergent boundary
what does the lava do once the seafloor spreads?
lava cools according to magnetic poles.
can oceanic crust collide with continental crust?
yes
what causes a transform boundary to occur?
when 2 plates slip past each other moving in opposite directions.
what are the 3 type of the tectonic boundaries?
divergent, convergent, transform
what is the process of subduction?
when the ocean floor sinks beneath a deep-ocean trench and back into the mantle.
what causes seafloor spreading?
convection currents
can oceanic crust collide with another oceanic crust?
yes
how do earthquakes occur in relation to transform boundary?
when fault lines break along earths crust.
what geological features are commonly associated with each boundary?
mid-ocean ridge, volcanoes/mountains, earthquakes
what plate tectonic boundaries cause subduction?
convergent plate bouderies
what is a characteristic of divergent boundary?
seafloor spreading
how does a convergent boundary occur?
its occurs when 2 plates come together or converge.
in relation to transform boundary what is the closest fault line to Kentucky?
New Madrid fault.
how do transform boundaries, like the San Andreas fault cause earthquakes?
when friction between the sliding tectonic plates prevents them from moving smoothly.
what geological features are created in subduction?
ocean trenches, volcanoes, and mountains
how does divergent boundary occur?
when 2 plates move apart or diverge.
what forms when there is a convent boundary?
volcanoes and deep sea trenches
in relation to transform boundary what is the most famous fault line in California?
San Andreas fault
how do plate tectonics influence the formation of mountains such as the Himalayas?
through a continental collision where the Indian plate continues to move northward and collide with eurasian plate.
how do subduction zones lead to the formation of volcanic arcs?
when a denser oceanic plate is forced beneath a lighter plate, descending into the hot mantle.
what do you call seafloor spreading at a divergent boundary?
mid-ocean ridge
what is it called when the plates are hitting together in convergent boundary?
collision
how do we know where the edges of plates are located?
how does convection in the mantle contribute to the movement of tectonic plates?
through slow circulating, density- driven currents of hot flowing rock within the Earths mantle.
what types of natural hazards are commonly associated with subduction zones?
earthquakes, tsunamis, vocanic eruptions, and landslides
