It is considered to be 'constructive,' because new crust is being formed and added to the ocean floor.
What else can I help you with?
What are spreading boundaries?
Spreading boundaries are places where two plates move apart.
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.
Does two plates moving apart cause sea floor spreading?
Yes, two tectonic plates moving apart can cause sea floor spreading. As the plates separate, magma rises up to fill the gap, solidifying to form new oceanic crust. This process contributes to the expansion of the ocean basins.
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 it called when two oceanic plates move apart and new crust is formed?
This process is called seafloor spreading. As the two plates move apart, magma rises from the mantle to create new crust at the mid-ocean ridge. This process helps explain the movement of Earth's tectonic plates and the reshaping of the ocean floor.
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.
What do you call the area where two tectonic plates meet?
The area where two tectonic plates meet is called a plate boundary. At plate boundaries, interactions between the plates can result in processes like subduction, seafloor spreading, or continental collision.
What two types of plates consist two the crust?
The Earth's crust is primarily made up of two types of plates: oceanic plates, which are denser and thinner, and continental plates, which are less dense and thicker. These plates interact at plate boundaries, where tectonic forces drive movements such as subduction, spreading, and collision.
Which of these is a boundary where two tectonic plates move away from each other leaving a newly constructed ridge in between?
divergent
Where do two of the earth's plates split apart?
The Mid-Atlantic-Ridge is where two of Earth's plates split apart. The Mid-Atlantic-Ridge was formed along a divergent boundary where seafloor spreading is taking place.
Sea-floor spreading occurs in places where two plates are doing what?
Sea-floor spreading occurs in places where two tectonic plates are moving away from each other. Magma rises to the surface, creating new crust as the plates separate. This process is a key mechanism driving the movement of Earth's lithosphere.
