What else can I help you with?
Why the crust is thinner than the ocean floor?
The Earth's crust is thinner than the ocean floor because the oceanic crust is formed at mid-ocean ridges where heat from the mantle creates new crust through volcanic activity. This process creates younger, hotter, and thinner crust in the ocean compared to the older and thicker continental crust.
What does oceanic crust make when it melts?
it creates a volcanoe
Is ocean crust formed at a mid ocean ridge?
Yes, the process that creates oceanic crust on a mid-ocean ridge is called "seafloor spreading". seafloor spreading creates a new oceanic crust that forms on the mid-ocean ridge.
What happens when continental crust push together?
It creates a mountain
Is new oceanic crust formed at mid-ocean ridges?
Yes, the process that creates oceanic crust on a mid-ocean ridge is called "seafloor spreading". seafloor spreading creates a new oceanic crust that forms on the mid-ocean ridge.
Is a new oceanic crust formed at a transform fault boundary?
No. New oceanic crust is formed at a divergent boundary. A convergent boundary neither creates nor destroys crust.
What boundary creates a crust?
The Divergent Boundaries.
What creates new crust as plates move away from each other?
Magma rises up from the earth's mantle and cools to create new crust.
What is the mechanism that creates a volcano?
The molten core of the planet releasing energy through the crust.
What type of boundary neither creates nor destroys oceanic crust?
Transform boundary.
What created divergent boundary?
creates new crust and allows magma to come through.
Subduction of oceanic crust at a continental margin creates .?
Ocean trenches and Island arcs.
