A divergent plate boundary often forms a mountain chain known as a ridge. This feature forms as magma escapes into the space between the spreading tectonic plates.
What are the 3 divergent plate boundaries?
2.4: Divergent Boundaries
Continental Rifting.Mid-Ocean Ridges.
Where are divergent plates?
Divergent boundaries are spreading boundaries, where new oceanic crust is created to fill in the space as the plates move apart. Most divergent boundaries are located along mid-ocean oceanic ridges (although some are on land).
What are 2 examples of divergent plates movement?
Examples of Divergent Boundaries
There it forms characteristics of a continental divergence, and a rift is forming on the island. Eventually, Iceland will break into two separate islands, with sea in between. The East African Rift is a continental divergent boundary in East Africa.
What do divergent boundaries create on land?
Plate Divergence on Land
A divergent plate boundary on land rips apart continents (Figure below). When plate divergence occurs on land, the continental crust rifts, or splits. This effectively creates a new ocean basin as the pieces of the continent move apart.
How is divergent boundary formed?
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 is divergent boundary class 9?
Complete answer: Divergent boundary is a linear feature in the theory of plate tectonics that takes place between two tectonic plates when they pull away from each other. This occurs due to the rise in convection currents.
What are the 4 types of plate boundaries?
There are four types of boundaries between tectonic plates that are defined by the movement of the plates: divergent and convergent boundaries, transform fault boundaries, and plate boundary zones.
What are the 4 types of tectonic plate movement?
What are the major plate tectonic boundaries?
Divergent: extensional; the plates move apart. Spreading ridges, basin-range.Convergent: compressional; plates move toward each other. Includes: Subduction zones and mountain building.Transform: shearing; plates slide past each other. Strike-slip motion.
What causes divergent plates to move?
Divergent boundaries occur along spreading centers where plates are moving apart and new crust is created by magma pushing up from the mantle. Picture two giant conveyor belts, facing each other but slowly moving in opposite directions as they transport newly formed oceanic crust away from the ridge crest.
What two interacting plates from the divergent plate boundary give at least 2 examples?
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 topographic feature is formed in divergent?
Most divergent plate boundaries are underwater and form submarine mountain ranges called oceanic spreading ridges.
What is a divergent movement?
Divergent (Spreading):This is where two plates move away from each other. Molten rock from the mantle erupts along the opening, forming new crust. The earthquakes that occur along these zones, called spreading centers, are relatively small.
What is a real world example of divergent boundary?
An example of an oceanic and oceanic divergent boundary is the mid-ocean ridge. The mid-ocean ridge runs around the world including going right through Ice land. A famous example of a continental and continental divergent boundary is the African rift valley.
Which of the following is an example of divergent boundary?
An example of a divergent boundary is the mid Atlantic Ridge (there are mid ocean ridges in the Indian, and Pacific Oceans as well). The Mid Atlantic Ridge creates volcanos where the hot magma erupts from the underlining mantle.
