Which plate boundaries are divergent?
A divergent boundary occurs when two tectonic plates move away from each other. Along these boundaries, earthquakes are common and magma (molten rock) rises from the Earth’s mantle to the surface, solidifying to create new oceanic crust. The Mid-Atlantic Ridge is an example of divergent plate boundaries.
What are 3 pairs of plates with divergent boundaries?
Divergent boundaries
- The East African Rift (Great Rift Valley) in eastern Africa.
- The Mid-Atlantic Ridge system separates the North American Plate and South American Plate in the west from the Eurasian Plate and African Plate in the east.
- The Gakkel Ridge is a slow spreading ridge located in the Arctic Ocean.
What are the 2 types of divergent boundaries?
There are two types of divergent boundaries, categorized by where they occur: continental rift zones and mid-ocean ridges. Continental rift zones occur in weak spots in the continental lithospheric plate.
What occurs at a divergent boundary?
At divergent boundaries, two plates move away from each other and the space that this creates is filled with new crustal material sourced from molten magma that forms below. The origin of new divergent boundaries at triple junctions is sometimes thought to be associated with the phenomenon known as hotspots.
What landforms are made at a divergent boundary?
Answer and Explanation: Two landforms that are created from divergent boundaries are rift valleys and mid-oceanic ridges.
What occurs at a convergent boundary?
If two tectonic plates collide, they form a convergent plate boundary. Usually, one of the converging plates will move beneath the other, a process known as subduction. Deep trenches are features often formed where tectonic plates are being subducted and earthquakes are common.
What is a divergent landform?
A divergent boundary is where two tectonic plates are moving away from each other, leaving a gap between them that can be filled with magma.
What plate boundaries are convergent?
When two tectonic plates move toward each other and collide, they form a convergent plate boundary. There are three types of convergent plate boundaries: oceanic-oceanic boundaries, oceanic-continental boundaries, and continental-continental boundaries. Each one is unique because of the density of the plates involved.
What are the 3 different types of plate boundaries?
Three types of convergent plate boundaries
What are the five plate boundaries?
Divergent: extensional; the plates move apart. Spreading ridges,basin-range.
What happens at a divergent plate boundary?
When two plates are moving away from each other, we call this a divergent plate boundary. Along these boundaries, magma rises from deep within the Earth and erupts to form new crust on the lithosphere. Most divergent plate boundaries are underwater and form submarine mountain ranges called oceanic spreading ridges.
What are the three types of plate movement?
– 3 TYPES OF PLATE BOUNDARIES. convergent. – CONVERGENT PLATE BOUNDARY. 2 plates collide (come together) – DIVERGENT PLATE BOUNDARY. 2 plates separate (pull apart) – TRANSFORM PLATE BOUNDARY. 2 plates slide past each other. – MID-ATLANTIC RIDGE. – HIMALAYAN MOUNTAINS. – AFRICAN RIFT VALLEY. – JAPAN TRENCH.
