Do divergent boundaries create or destroy lithosphere?
Divergent plate boundaries always create new ocean floor (that is, new mafic oceanic lithosphere, called the ophiolite suite) when magma oozes into the crack as plates separate. The implication is, ocean basins get larger at divergent plate boundaries.
What happens to the lithosphere in a divergent 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.
Do divergent boundaries cause construction or destruction?
The plates diverge and this causes the construction of new rock. It happens when two tectonic plates pull apart and rock from the mantle rises up through the opening to form new surface rock when it cools.
Which plate boundary destroys lithosphere?
Convergent boundaries exist where lithosphere is destroyed, as one plate sinks below the other (e.g., at oceanic trenches). Transform boundaries do not produce or destroy lithosphere, rather one block of the lithosphere slides horizontally past each other (Wilson, 1965).
What happens to the lithosphere at Transform plate boundaries?
What happens to the lithosphere at transform plate boundaries? Lithosphere moves down. Lithosphere is neither destroyed nor created, simply maintained or conserved.
What does divergent plate boundaries cause?
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.
Is lithosphere created or destroyed?
Lithosphere is neither created nor destroyed along transform boundaries which connect segments of spreading oceanic ridges and other plate boundaries.
How does a convergent boundary differ from a divergent boundary?
Divergent boundaries — where new crust is generated as the plates pull away from each other. Convergent boundaries — where crust is destroyed as one plate dives under another.
What happens in divergent plates?
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.
When a divergent boundary occurs beneath oceanic lithosphere?
When a divergent boundary occurs beneath oceanic lithosphere, the rising convection current below lifts the lithosphere, producing a mid-ocean ridge. Extensional forces stretch the lithosphere and produce a deep fissure. When the fissure opens, pressure is reduced on the super-heated mantle material below.
What happens at convergent and divergent plate boundaries?

How is lithosphere destroyed?
Old oceanic lithosphere is destroyed when it subducts or dives beneath adjacent plates at subduction zones. Oceanic trenches are the topographic expression of these subduction zones. Oceanic lithosphere behaves differently from continental crust, being denser.
How is molten rock formed at divergent boundaries?
This reduction in overlying pressure, or decompression, enables the mantle rock to melt and form magma. Decompression melting often occurs at divergent boundaries, where tectonic plates separate. The rifting movement causes the buoyant magma below to rise and fill the space of lower pressure.
What type of lithospheric plate boundary is found?
Divergent plate boundaries are regions where lithospheric plates are moving away, or diverging from each other under the sea. In contrast to convergent boundaries that destroy old crust by subduction, divergent boundaries create new crust through a form of volcanism.
What can happen at the lithospheric plate boundaries?
Earthquakes, volcanic activity, mountain-building, and oceanic trench formation occur along plate boundaries in zones that may be anything from a few kilometres to a few hundred kilometres wide.
What is lithosphere neither created nor destroyed?
Where tectonic plates slip horizontally past one another, lithosphere is neither created nor destroyed. Instead, blocks of crust are torn apart in a broad zone of shearing between the two plates.
What transform fault is occurs in lithosphere?
Oceanic transform faults are long-term stable features and are intrinsic elements of the spreading process (Gerya, 2010, 2012). They are also present in continental lithosphere, where they may connect segments of subduction zones or a spreading ridge and a collision zone (Gerya, 2016 and references therein).
When a divergent boundary occurs beneath oceanic lithosphere the rising convection current below lifts the lithosphere What does it produce?
Answer. Answer: When a divergent boundary occurs beneath oceanic lithosphere, the rising convection current below lifts the lithosphere, producing a mid-ocean ridge. Extensional forces stretch the lithosphere and produce a deep fissure.
How do the lithospheric plates move at a divergent margin quizlet?
The continental crust is thicker and less dense than oceanic crust. How do plates move at divergent plate boundaries? Plates move apart.
Where do divergent boundaries occur?
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 geographical structure is formed at a divergent boundary?
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 landforms are created by divergent boundaries?
At DIVERGENT boundaries the plates move apart allowing molten magma to rise and form new crust in the form of ridges, valleys and volcanoes. Landforms created by divergent plates include the Mid Atlantic Ridge and the Great African Rift Valley.
How can you distinguish a divergent boundary from a convergent boundary using features found on the Earth’s surface?
How can you distinguish a divergent boundary from a convergent boundary using features found on the Earth’s surface? A convergent boundary has volcanic activity, while a divergent boundary does not.
How does a convergent boundary differ from a divergent boundary quizlet?
A convergent boundary is where plates come together and a divergent boundary is where they move apart from each other.
Do divergent plate boundaries create volcanoes?
Volcanoes are most common in these geologically active boundaries. The two types of plate boundaries that are most likely to produce volcanic activity are divergent plate boundaries and convergent plate boundaries.
What happens at a divergent plate boundary quizlet?
What happens at a divergent boundary? – When two continental plates diverge, a valley like rift develops. This rift is a dropped zone where the plates are pulling apart. As the crust widens and thins, valleys form in and around the area, as do volcanoes, which may become increasingly active.
Which igneous rock type is associated with divergent plate boundaries?
Mafic (basaltic) and ultramafic magmas form along the divergent midoceanic ridges and are major components of new oceanic crust. More felsic magmas, such as andesites and rhyolites, are associated with the edges of continental crust at subduction zones along converging plate boundaries.
What plate boundary is gabbro formed?
Divergent boundary: In the oceanic crust, basalt forms near the surface at a divergent boundary, but gabbro forms at depth from slow crystallization.
How do divergent plate boundaries cause earthquakes?
Earthquakes at divergent plate boundaries occur as new crust is created and other crust is pushed apart. This causes the crust to crack and form faults where earthquakes occur. Most earthquakes at divergent plate boundaries occur at mid-ocean ridges where two pieces of oceanic crust are moving away from each other.
What happens at a divergent boundary apex?
At a divergent boundary the plates move apart from each other as fresh magma rises to the surface to create new crustal material.
What happens at divergent plate boundaries resulting in the melting of rocks?
At divergent plate boundaries hot mantle rock rises into the space where the plates are moving apart. As the hot mantle rock moves upwards, less material is pushing down on it and the pressure decreases. The rock is under lower pressure; this lowers the melting temperature of the rock and so it melts.
How do plates move relative to each other at a divergent plate boundary?
At divergent boundaries, plates move apart from each other. When this happens, new plate material forms. Two plates pushed together create a convergent fault. If one plate is oceanic and the other continental, the edge of the oceanic plate will be pushed down.
What happened to the oceanic lithosphere or plate Why?
Seafloor Processes
Oceanic lithosphere forms at midocean ridges, where hot magma upwells, and then cools to form plates as the material moves away from the spreading center. As the plate cools, heat flow decreases and the seafloor deepens (Fig. 3).
Which type of plate boundary exists when there is no destruction or formation of new lithosphere?
Transform boundaries exist where one plate slides past another without production or destruction of crustal material.
What do you know about the lithosphere plates?
A tectonic plate (also called lithospheric plate) is a massive, irregularly shaped slab of solid rock, generally composed of both continental and oceanic lithosphere. Plate size can vary greatly, from a few hundred to thousands of kilometers across; the Pacific and Antarctic Plates are among the largest.
Why does oceanic lithosphere almost always sink beneath continental lithosphere at convergent zones?
Near which type of lithospheric plate boundary are andesite stratovolcanoes most common? Why does oceanic lithosphere almost always sink beneath continental lithosphere at convergent plate boundaries? A. Oceanic lithosphere moves so slowly that it can only sink.
Is lithosphere destroyed at convergent boundaries?
At convergent boundaries oceanic lithosphere is always destroyed by descending into a subduction zone. This is because oceanic rock is mafic, and heavy compared to the continents, and sinks easily.
What plate boundary destroys lithosphere?
Convergent boundaries exist where lithosphere is destroyed, as one plate sinks below the other (e.g., at oceanic trenches). Transform boundaries do not produce or destroy lithosphere, rather one block of the lithosphere slides horizontally past each other (Wilson, 1965).
What makes up the lithosphere?
The lithosphere is the rocky outer part of the Earth. It is made up of the brittle crust and the top part of the upper mantle. The lithosphere is the coolest and most rigid part of the Earth.
Where is lithosphere destroyed?
At what location is the most lithosphere destroyed? The lithosphere is created in the mid ocean ridge. It is destroyed in the earth’s interior.
What happens to the lithosphere at Transform plate boundaries?
What happens to the lithosphere at transform plate boundaries? Lithosphere moves down. Lithosphere is neither destroyed nor created, simply maintained or conserved.
What happens to the lithosphere at convergent plate boundaries?
As oceanic lithosphere cools, it becomes denser, and the further away from the plate boundary it moves, the thicker it becomes. At a convergent plate boundary the oceanic lithosphere sinks beneath the adjacent plate in a process known as ‘subduction’.
What geologic event’s is are most likely to happen at transform fault boundary?
earthquake is the right answer.
What movement is observed between the Philippine plate and the Eurasian Plate?
Philippine Sea Plate is an oceanic plate surrounded by subduction zones. The plate is moving northwest at a rate of 6 – 8 cm/year towards the Eurasian Plate.
What is the motion of divergent boundary?
At divergent boundaries, plates move away from each other. At convergent boundaries, plates move towards each other. At transform boundaries, plates move alongside each other.
How do the lithospheric plates move at a divergent margin?
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.
Which plate boundaries do lithospheric plates quizlet?
Lithospheric plates move toward each other along convergent boundaries. This can either result in new mountain ranges or subduction zones.
What makes lithospheric plates move?
Plate Tectonics
The lithosphere is divided into huge slabs called tectonic plates. The heat from the mantle makes the rocks at the bottom of lithosphere slightly soft. This causes the plates to move.
Where is a divergent boundary most likely to be found quizlet?
Most are in the ocean (Mid Atlantic Ridge). The Great Rift Valley in Africa is an example of a divergent plate boundary on land.
Where do most divergent boundaries originate quizlet?
-Most divergent plate boundaries are located along the crests of ocean ridges.

When a divergent boundary occurs beneath oceanic?
Answer: When a divergent boundary occurs beneath oceanic lithosphere, the rising convection current below lifts the lithosphere, producing a mid-ocean ridge. Extensional forces stretch the lithosphere and produce a deep fissure. When the fissure opens, pressure is reduced on the super-heated mantle material below.
