What is the difference between divergent plate boundaries and convergent plate boundaries?
Okay this is going to be long :X
IN GENERAL...
Divergent Plate Movement (plates move away from each other)-
Continental and continental, oceanic and oceanic
-Constructive Plate Boundary
Convergent Plate Movement (plates move towards each other)-
Continental and Oceanic, Oceanic and Oceanic, Continental and Continental
-Destructive Plate Boundary
Transform Plate Movement (plates sliding past each other)-
Continental and Continental
-Conservative Plate Boundary
DIVERGENT PLATE MOVEMENT
When plates move apart, magma wells up from Earth's mantle to form a new ocean floor with mid-oceanic ridges.
It is a constructive plate boundary because new land crust is being created.
O & O (Oceanic and Oceanic)
Oceanic Ridges and Submarine volcanoes are formed. Shallow earthquakes may occur and there may be volcanic activity.
Magma from the deeper mantle wells up into the gap formed when two oceanic plates move away from each other, and some of it melts and is erupted on the surface as lava, while others are injected near the surface to crystallize as other igneous rocks.
The seafloor may also spread, and magma rises to the floor and solidify, forming new crust. Therefore it is a constructive plate boundary as new crust is formed and added to the ocean floor. An example of the resulting landforms would be the Mid-Atlantic Ridge.
C & C (Continental and Continental)
When two continental plates move away from each other, a sea is formed. E.g. Red Sea.
CONVERGENT PLATE MOVEMENT
When plates move towards each other, they may collide.
When 2 oceanic plates collide, plate edges are bent into a deep trench called the subduction zone. It is a destructive plate boundary because the subducted plate is destroyed in the process.
O & O
Subduction takes place, and the over-riding plate (the plate above) folds and form islands, whilst the heavier plate sinks into the mantle of the Earth and is melted away by the magma. The magma rises and forms volcanoes. E.g. Japan.
C & O
When an oceanic plate collide with a continental plate, the oceanic plate sinks as it has a larger density. Lithosphere materials from the oceanic crust are subducted in the trench whilst the continental border is fractured, folded and uplifted. Magma rises and a mountain accompanied by volcanic activity are formed.
E.g. Andes Mountains.
C & C
When two continental plates collide, neither sinks because they have similar densities. The continental lithosphere buckles and is uplifted instead, forming fold mountains. Little volcanic activity occur as rocks from the lithosphere do not sink deep into the asthenosphere (upper mantle zone) Earthquakes, faulting and folding however, are common.
E.g. Himalayas.
TRANSFORM PLATE MOVEMENT
Occurs when two plates slip past each other. Tear faults form, accompanied by earthquakes due to great amount of stress built up in these areas, but there is little volcanic activity and little crustal material is destroyed.
What else can I help you with?
What are the key differences between divergent and convergent boundaries in plate tectonics?
Divergent boundaries occur when tectonic plates move away from each other, creating new crust, while convergent boundaries happen when plates collide, leading to the destruction or subduction of crust.
Breaks between plates are known as what?
Breaks between plates are known as plate boundaries. These boundaries can be divergent, convergent, or transform, and the type of boundary determines the type of interactions between the plates.
What are the four types of plate boundaries?
The four types of plate boundaries are divergent boundaries, where plates move apart; convergent boundaries, where plates collide; transform boundaries, where plates slide past each other horizontally; and plate boundary zones, which encompass areas where interactions between multiple plates occur.
Where do major interactions between tectonic plates occur?
Major interactions between tectonic plates occur along plate boundaries, including convergent boundaries where plates collide, divergent boundaries where plates move apart, and transform boundaries where plates slide past each other. These interactions result in various geological features like mountain ranges, oceanic trenches, and volcanic activity. Some well-known examples of plate interactions include the Himalayas forming at the convergent boundary between the Indian and Eurasian plates, and the Mid-Atlantic Ridge at a divergent boundary in the Atlantic Ocean.
Three types of plate boundaries?
Convergent (or destructive): Where two plates are moving toward each other. Collisions between oceanic plates results in subduction of the more dense plate. Collisions between an oceanic plate and a continental plate may result in the subduction of the oceanic plate because oceanic plates are more dense than continental plates. Collisions between two continental plates results in uplift and mountain formation where neither plate subducts.Divergent (or constructive): Where two plates are moving away from each other. Divergent plate boundaries are the site of new crust formation, particularly at the mid-ocean ridges, where spreading plates are infilled with basaltic magma from the asthenosphere.Transform (or conservative): Where two plates slide (actually 'grind') alongside each other and neither plate subducts. Earthquakes are common at transform faults due to the grinding and snapping movements of the plates as they move.
What is the similarities between convergent divergent and transform boundaries?
they both form volcanoes and earthquakes
Is Mount Vesuvius near a hot spot divergent or convergent plate boundary?
Vesuvius is associated with a convergent boundary between the African Plate and the Eurasian Plate.
What the difference between convergent and divergent?
Two paths which are convergent will come together in the distance. Two paths which are divergent will get further and further apart in the distance.
What are the key differences between divergent and convergent boundaries in plate tectonics?
Divergent boundaries occur when tectonic plates move away from each other, creating new crust, while convergent boundaries happen when plates collide, leading to the destruction or subduction of crust.
What are some similarities with convergent and divergent boundaries?
Some similarities between convergent and divergent boundaries are that both create faults that are capable of producing earthquakes; both are tectonic plates; and both are part of the lithosphere.
What kind of plates cause volcanoes?
Plates do not cause volcanoes. Volcanoes generally form at the boundaries between plates. They form at convergent and divergent boundaries.
What is the difference between convergent boundary and convergent plate boundary?
Convergent means where plates are moving together. Divergent means where plates are moving apart.
What are the differences between the three types of plate boundaries?
divergent, transform and convergent divergent plate boundaries move away from each other, convergent plate boundaries move toward each other, and transform plate bounties slide past each other.
What kind of boundaries can cause earthquakes and volcanoes?
Earthquakes can occur at any type of plate boundary, but the most powerful earthquakes tend to occur at convergent boundaries and at transform boundaries.
What is the difference between convergent and divergent and transform boundaries?
Convergent boundaries involve two tectonic plates moving towards each other, resulting in the creation of mountains, earthquakes, and volcanic activity. Divergent boundaries occur when two plates move away from each other, leading to the formation of new crust and mid-ocean ridges. Transform boundaries involve two plates sliding past each other horizontally, causing earthquakes along fault lines.
Breaks between plates are known as what?
Breaks between plates are known as plate boundaries. These boundaries can be divergent, convergent, or transform, and the type of boundary determines the type of interactions between the plates.
What is the boundary between plates?
The boundary between plates is called a plate boundary, which is where tectonic plates meet. These boundaries can be divergent, convergent, or transform faults, and are characterized by various geological activities such as earthquakes, volcanic eruptions, and mountain building. Plate boundaries are dynamic regions where the Earth's lithosphere is constantly changing.
