What else can I help you with?
When two oceanic plates collide it creates?
when two oceanic plates collide they create a deep-ocean trench, at deep-ocean trenches subduction occurs.
Where two plates collide and force down the ocean floor?
That is called subduction.
When two of earths ocean plates collide they can form a deep valley called?
When two of Earth's oceanic plates collide, they can form a deep valley called a trench. Trenches are often found in subduction zones where one plate is forced beneath the other, creating a deep depression in the ocean floor.
When ocean plates collide with continental plates what does the denser plate do?
sinks
When ocean plates collide with continental plates the denser oceanic plate?
sinks
When oceans plates collide with continental plates the denser ocean plate does what?
sinks
What happens when sea-floor speading occurs?
the process by which new material is added to the ocean floor along the boundary between diverging plates.
Old ocean floor is destroyed and absorbed by the Earth and remelted beneath what?
Old ocean floor is destroyed and absorbed by the Earth at subduction zones, where tectonic plates collide and one plate is forced beneath the other. The remelting occurs beneath volcanic arcs, where the subducted crust melts and rises to the surface as magma, leading to the formation of new crust.
What is things rest upon crustal plates?
The continents and the ocean floor rest upon the plates.
Are formed when two ocean plates collide?
volcanoes in an island arc
Is it true or false that when sea floor spreading occurs new crust is added to the ocean floor?
True. Sea floor spreading occurs at mid-ocean ridges, where tectonic plates diverge and magma rises from the mantle to create new oceanic crust. As this new crust forms, it pushes the older crust away from the ridge, contributing to the expansion of the ocean floor.
What are the differences between oceanic crust and continental crust in age terms?
Overall their materials are of the same age, but the continental plates simply break or collide whereas the ocean-floor plates are in constant cycles of construction and destruction.
