How is new crust continually being formed?
new crust is always being formed by magma erupting from volcanoes and then cooling into rock making new crust. -Jacob Halon
Why isn't new oceanic crust generated along volcanic island arcs?
At a volcanic island arc, an oceanic plate slides into the mantle and thus oceanic crust is destroyed. The volcanoes add material on to of the crust, but to not cause the crust to expand outward.
How can crust disappear at the edge of a boundary?
New crust is being added to the other edge of the boundary
The Earth's magnetic field is generated by the dynamo effect in the?
the crust
Why does new crust form but the earth doesn't get larger?
As new oceanic crust is being made in one area older crust is being subducted, (pushed or pulled down), in another area, so Earth stays about the same size.
Where new crust is being formed?
New oceanic crust is continually being created at the Mid-Ocean ridges.

How does the age of oceanic crust compare to the age of continental crust?
Oceanic crust is generally much younger. New ocean crust is constantly being formed.
Does seafloor spreading cause the earth's crust to expand?
New oceanic crust is being created at seafloor spreading zones, and crust is alternately being subducted and destroyed at subduction zones.

Why is rock formed at th ridges called new rock?
Since the rock just came up and cooled, it's "new oceanic rock." Because... it's new rock. It's the youngest rock. It just came out of the ground and cooled, making it rock. Or Because new crust is being formed while the old crust is being pushed away.
Is subduction zone is where new crust is being formed?
No. As crust subducts under another plate, it is destroyed (Convergent Boundary). When plates pull apart, new crust is formed (Divergent Boundary).
