What happens when tectonic plates diverge?

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. It happens at the start of a new ocean and continues at the mid-ocean ridge while the ocean is opening.

What happens to tectonic plates at a divergent boundary quizlet?

divergent boundaries are where two lithospheric plates move apart and new plate (crust) are created at the boundary. This process always produces ocean crust and thus oceanic plate.

Which of the following can be both a destructive force and a constructive force?

Common constructive and destructive forces include volcanoes erosion weathering and deposition and many others. Constructive Earth processes are changes that add to the surface of the Earth and some of them take millions of years to occur. The Hawaiian Islands are a great example of a slow constructive change.

Which of the following terms is considered a constructive force?

The processes for building new land are called constructive forces. Three of the main constructive forces are crustal deformation volcanic eruptions and deposition of sediment. Crustal deformation occurs when the shape of land (or crust) is changed or deformed.

What is a divergent tectonic plate?

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.

Do divergent plates cause earthquakes?

Shallow low-magnitude earthquakes commonly occur at divergent plate boundaries. … 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 is formed at a divergent plate 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 happens to tectonic plates at a divergent boundary recycled or formed?

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 happens at a divergent boundary quizlet?

What is a Divergent Boundary? When two plates move away from each other which causes magma to come up forming new crust (oceanic) and creates a valley for water t stream in.

Are tectonic plates constructive or destructive?

They are called constructive plates because when they move apart magma rises up in the gap- this forms volcanoes and eventually new crust. One example is the Mid-Atlantic Ridge where the gap can be found in Thingvellir Iceland. Destructive plate boundaries are when oceanic and continental plates move together.

Is faulting constructive or destructive?

Landforms are a result of a combination of constructive and destructive forces. Collection and analysis of data indicates that constructive forces include crustal deformation faulting volcanic eruption and deposition of sediment while destructive forces include weathering and erosion.

Why do most volcanoes occur along convergent and divergent margins?

Volcanoes are common along convergent and divergent plate boundaries but are also found within lithospheric plates away from plate boundaries. … Along subducting plate boundaries the crust heats up as it sinks into the mantle. Also ocean water is mixed in with the sediments lying on top of the subducting plate.

Is a delta formed by constructive or destructive?

A Delta is a constructive force. erosion takes broken sediment and deposition deposits the sediment in a new place in order to make a delta.

Is the Grand Canyon constructive or destructive?

The two mechanisms at work to construct the Colorado Plateau and the Grand Canyon are uplift (constructive) and erosion (destructive).

Is a sand dune formed by a constructive or destructive force?

A constructive force affects the earth’s surface by building it up while forming new crust and landforms like mountains islands deltas and sand dunes.

Is formed by divergence of two oceanic plates?

In the case of divergent plate boundaries two of earth’s plates move away from each other. … On the other hand if two oceanic plates diverged a mid ocean ridge would form which is also known as a spreading center. Divergent plate boundaries are commonly associated with shallow earthquakes.

What geologic feature is formed between the divergent oceanic plates?


Divergent zones in oceanic plates form a geological feature called a ridge forced upward by the pressure of the rising magma. The Mid-Atlantic Ridge is an example of an oceanic divergent boundary formation.

Where do divergent boundaries occur?

mid-ocean oceanic ridges
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 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.

Why are divergent boundary earthquakes weak?

Earthquakes at Divergent and Transform Plate Boundaries. Earthquakes along divergent and transform plate margins are shallow (usually less than 30 km deep) because below those depths rock is too hot and weak to avoid being permanently deformed by the stresses in those settings.

Is the San Andreas Fault convergent or divergent?

Tectonic setting of the San Andreas Fault (transform plate boundary) in California the subduction zone (convergent plate boundary: oceanic-continental collision) in the Pacific Northwest.

Which two formations are caused by divergent plates?

Valleys and oceanic ridges are formed at divergent plate boundaries.

What kind of landform is created at divergent?

Two landforms that are created from divergent boundaries are rift valleys and mid-oceanic ridges.

Is the lithosphere created or destroyed in divergent plate boundary?

At these divergent plate boundaries new oceanic lithosphere is created in the gaps from upwelling magma from the mantle. This upwelling magma forms mid-ocean ridges long mountain chains that mark the boundaries between diverging plates.

Do divergent plate boundaries result in construction or destruction of lithosphere?

Since the divergent plate boundaries are the regions for the construction of new crust the boundary shown in figure results in the construction of new lithospheric crust.

How does a convergent boundary differ from a divergent boundary?

A convergent boundary is where plates come together and a divergent boundary is where they move apart from each other.

What forms at a divergent boundary quizlet?

What forms at divergent plate boundaries? New oceanic lithosphere form at divergent plate boundaries. In general where do volcanoes form in subduction zones? In general volcanoes form on the overriding plate away form the convergent boundary.

What is formed at a divergent boundary in the ocean quizlet?

divergent plate boundaries lead to the formation of new lithosphere. This creation of new crustal material takes place at mid-ocean ridges where the oceanic crust is rifted open and magma wells up to fill the opening. The magma then hardens to form the igneous rocks that make up the oceanic crust.

How do earthquakes form at destructive plate boundary?

Destructive plate margins

A destructive plate margin usually involves an oceanic plate and a continental plate. The plates move towards one another and this movement can cause earthquakes. … When the plate sinks into the mantle it melts to form magma. The pressure of the magma builds up beneath the Earth’s surface.

How do volcanoes form at destructive plate boundaries?

At a destructive plate boundary (also called convergent boundaries) two plates move towards another. One plate is then pushed underneath the other. … The plate then melts due to friction to become molten rock (magma). The magma then forces its way up to the side of the plate boundary to form a volcano.

Which of the following is the major mechanism of movement in the divergent boundary?

Divergent plate boundaries are locations where plates are moving away from one another. This occurs above rising convection currents. The rising current pushes up on the bottom of the lithosphere lifting it and flowing laterally beneath it.

What fault is caused by compression?

reverse fault

Compressional stress meaning rocks pushing into each other creates a reverse fault. In this type of fault the hanging wall and footwall are pushed together and the hanging wall moves upward along the fault relative to the footwall. This is literally the ‘reverse’ of a normal fault.

What is denudation process?

Denudation is the name for the processes of erosion leaching stripping and reducing the mainland due to removal of material from higher to lower areas like valleys river valleys lakes and seas with a permanent filling of low lands.
