What type of plate boundary is formed when plates separate?
divergent boundaries
At divergent boundaries, plates separate, forming a narrow rift valley. Here, geysers spurt super-heated water, and magma, or molten rock, rises from the mantle and solidifies into basalt, forming new crust. Thus, at divergent boundaries, oceanic crust is created.
What is formed when plates separate?
The Mid-Ocean Ridge and rift valleys, such as the one that runs through eastern Africa, occur along boundaries where plates are spreading apart. New oceanic crust is created as the plates separate and molten rock rises up from the mantle and fills the space.
What is a separating plate boundary?
Separating plate boundaries are places where two plates pull apart or separate from each other. The Mid-Atlantic Ridge Rift is an example of a separating plate boundary. Magma rises up through the rift. When it meets the sea water, it cools rapidly to form a basaltic rock.
What causes plates to move apart?
Divergent boundaries
Divergent boundaries. Divergent boundaries occur along spreading centers where plates are moving apart and new crust is created by magma pushing up from the mantle.
What are the 4 types of plate boundaries?
Tectonic Plates and Plate Boundaries
- Convergent boundaries: where two plates are colliding. Subduction zones occur when one or both of the tectonic plates are composed of oceanic crust.
- Divergent boundaries – where two plates are moving apart.
- Transform boundaries – where plates slide passed each other.
What are the four types of plate boundaries?
The point where two or more plates meet is known as a plate boundary. There are four main types of plate boundary. These are constructive, destructive, conservative and collision margins.
What are the four plate boundaries?
Whatever drives the movement, plate tectonic activity takes place at four types of boundaries: divergent boundaries, where new crust is formed; convergent boundaries, where crust is consumed; collisional boundaries, where two land masses collide; and transform boundaries, where two plates slide against each other.
What are the names of the three plate boundaries?
There are three kinds of plate tectonic boundaries: divergent, convergent, and transform plate boundaries. This image shows the three main types of plate boundaries: divergent, convergent, and transform. Image courtesy of the U.S. Geological Survey. A.
What are the different plate boundaries?
Earth’s outer layer, the crust, is divided into a set of large moving plates. The lines where they meet are called plate boundaries. There are three main types of plate boundary: divergent, convergent and transform.
