Divergent plates are plates that move away from each other. They move away from each other because between them is volcanic activity. The magma seeps up through the cracks between the plates, cooling from the water. As it cools, it is pushed away from the edge by the rising magma from underneath. If you've ever watched gravy or tomato soup boil, the bubble coming from the bottom of the pan pushes the top fluid away from where the hotter liquid wants to go...which is straight up. So the ocean floor in these areas is basalt columns. (On the other side of the plates which are moving apart from each other are subduction zones.)

∙ 12y agoThe weakness of the asthenosphere allows the tectonic plates to move easily, which causes the gravitational sliding of lithosphere plates away from them.

What process causes earths plates to move?
The process of 'earth plates moving' is Alfred Wageners theory of continental drift. This theory proposes that convenction currents in the earths mantle provides a 'cushion' on which the plates can move.
Plates move apart because of?
the plates move apart because of plate boundaries !:)
What do plates move apart along on?
Plates move apart on divergent plate boundaries.
What happens when two plates move apart from each other?
what happends when to plates move apart they make volcanos
What happens as earths mantle drags on the bottom of techtonic plates?
The plates move
Do Earths Tetonic plates move apart?
Yes they do.
What causes earths plates to move continuously?
Convection in the earth's mantle.
The lithosphere is broken into pieces called what?
what causes the earths tectonic plates to move
What causes earths changes to earths landforms?
the tectonic platesthe tectonic plates can be move to be far and near to each other
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.
What is the name of the boundary were to plates of the earths crust move apart?
Constructive because new land is 'constructed'
What process causes earths plates to move?
The process of 'earth plates moving' is Alfred Wageners theory of continental drift. This theory proposes that convenction currents in the earths mantle provides a 'cushion' on which the plates can move.
What do plates move apart on?
Plates move apart on divergent plate boundaries.
Why do the Earths plates move?
because they are pushing against one another and so it causes fricton. when there is fricton the plates move and create a earth quake and or creves
How does the movement of earths plates cause earthquakes?
The plates rub together causing the rocks to move and it causes the ground to shake forming an earthquake. The more the plates move, the bigger the earthquake number.
Why do earthquakes and volcanoes occur?
because of the plates in earth shift fast and the force causes the earth to shake.
Are most volcanoes on land caused by the earths plates moving away form each other?
Sometimes it causes earthquakes, as well as when earths plates move in opposite directions. But yes, volcanoes are also formed when these plates move out of place or away from each other, for example Hawaii. That is an example of plates sliding through the ocean which causes islands.
