Constructive Plate Boundaries make Volcanoes. The Oceanic Plate (Sea) is in between two Continental Plates (Land). Both Constructive Plates are being pulled in their respective directions and the Oceanic Plate is stuck in the middle. It forms a crack in the centre and this then allows the magma from under the Earths Crust to rise up through the crust to form a cone shaped structure of magma. The magma cools and is left as rock, therefore having a volcano.

Was Brasstown Bald formed by a constructive or destructive force?

Constructive because two tectonic plates pushed together and pushed it up.


What convergent plates?

when the land is pushed farther apart to form more land


What is the name of the boundary were to plates of the earths crust move apart?

Constructive because new land is 'constructed'


How was the mount meakan volcano formed?

Plates pushed together makes mountains therefore plates pulled apart makes volcanos


Which plates are constructive?

Divergent plates.


What are divergent boundaries also called?

They are called constructive boundaries. New crust is constructed as the plates move apart and magma erupts.


When do tectonic plates separate one another?

The plates which are constantly moving move apart at divergent boundaries. These are also called constructive boundaries because of the fact that new magma rises here and heals the diverging plates.


What is a boundary between plates that are moving away from each oher?

A boundary where the plates are moving apart is called a divergent boundary. It is also called a constructive boundary because new crust is made there.


Why is the spreading apart of plates considered constructive?

The spreading apart of plates is considered constructive because it results in the creation of new crust along divergent boundaries. As the plates move apart, magma from below the Earth's surface rises to fill the gap, solidifies, and forms new crust. This process leads to the growth of the Earth's surface and contributes to the renewal of oceanic basins.


How are the pushed together and pulled apart?

Both continental and oceanic plates float on the top surface of the mantle, which is divided into convection cells. The movement of these convection cells drag the plates along: where convection causes the mantle material to fall the plates are pushed together and where convection causes the mantle material to rise the plates are pulled apart.


What are constructive plates?

Constructive plate margins are when two plates move away from each other, creating more ocean floor.


What causes magma to rise to earths surface?

The magma is in the mantle, the layer under the crust. There is a convection current caused by radioactivity in the inner core which causes the plates to move. Therefore the constructive plates move apart which means magma can rise up. It'll then solidify and this is what makes volcanoes. Hence CONSTRUCTive.
