Crust is formed at the edge of a tectonic plate by, when a volcano erupts, the lava or magma (same thing) hits the edge of a tectonic plate and cools and dries on the edge of that tectonic plate.
New crust will form at a plate boundary when two or more tectonic plates pull away for each other and a fissure forms. Runny lava -similar to that of a shield volcano- will pour out. If the fissure is formed at a oceanic plate the lava will cool against the water and form new crust. Additionally, over a 'hot spot' in a oceanic plate a volcano may form. When that volcano erupts the lava will come in contact with the water around it and for an island.
magma rising up from the mantle at a divergent boundary
A divergent/constructive plate boundary
Divergent boundary
Good Question person.
Sea floor spreading
A divergent boundary.
a-plus new crust forms as plates collide
No. New oceanic crust is formed at a divergent boundary. A convergent boundary neither creates nor destroys crust.
New crust is being added to the other edge of the boundary
Divergent Boundary, (Constructive Boundary).
No. As crust subducts under another plate, it is destroyed (Convergent Boundary). When plates pull apart, new crust is formed (Divergent Boundary).
a-plus new crust forms as plates collide
because the molten rock cools in the water and forms a oceanic crust
No. New crust is created along a divergent boundary. Crust is destroyed at a convergent boundary.
No. New oceanic crust is formed at a divergent boundary. A convergent boundary neither creates nor destroys crust.

Divergent plate boundary.
The type of boundary that forms when the crust of one plate is pushed down under another plate and turned into molten rock is referred to as a convergent boundary. Convergent boundaries form when oceanic crust slides beneath continental crust.
Divergent Boundary, (Constructive Boundary).
This would be called a Spreading center, or a divergent plate boundary.
No. As crust subducts under another plate, it is destroyed (Convergent Boundary). When plates pull apart, new crust is formed (Divergent Boundary).
