It is considered to be 'constructive,' because new crust is being formed and added to the ocean floor.

What are spreading boundaries?
Spreading boundaries are places where two plates move apart.
Does two plates moving apart cause sea floor spreading?
yes it does, floor spreading caused by shifting techtonic plates in active ocean
What happens to spreading boundaries?
SPREADING ZONES Spreading zone occurs in the border of two tectonic plates. This happens when the plates generally move away from each other creating an opening for the magma to force through the surface.
The Mid-Atlantic Ridge is an example of?
A spreading ridge, where two plates diverge.
What is spreading in regards to geology?
Spreading is generally thought of when speaking of sea-floor spreading. Sea-floor spreading takes place at the mid-ocean ridge where two oceanic plates are spreading/pulling apart from one another.
What is it called when two oceanic plates move apart and new crust is formed?
Seafloor Spreading
What is it called when two ocean plates move apart and new crust is formed?
Seafloor spreading
What is the Great Rift Valley of East Africa an excellent example of?
The spreading of plates from a divergent boundary that divides an existing landmass into two separate plates.
What Is the mechanism responsible for producing the new seafloor between two diverging plates?
Sea Floor spreading
What to plates cause the volcano arenal?
what plates are causing the arenal volcano to from
Place where seafloor spreading occurs?
Seafloor spreading occurs at the boundary between two tectonic plates. As the plates divide, magma comes up through the crack and cools to form new sea floor. The farther away the floor is from the boundary, the older it is.
How are the plates moving at the mid ocean ridge?
Because diverging plate boundaries occur at mid-ocean ridges, this means the two lithospheric plates are spreading apart.
