Depends on the type of plate boundary, at a mid-ocean ridge the plates move away from eachother. Ridges can also occur as a result of plate collision where the top layer of lithosphere is scraped off the subducted slab, this is called an accretionary prism.

What happens when earth's plate move?

when the earths plates move we either have earthquakes, tsunamis, and we get ridges and trenches.


How do tectonic plates move at a transform boundary?

At transform boundaries, the plates move horizontal in relation to each other.


Where would two plates move apart at mid-oceanic ridges?

at a divergent plate boundary


How fast do the plates move in the relation to each other year?

The earth's plates move slowly because how big the earthquake is he bigger the amount the plates will move and the slower the earthquake is the less it moves.


Boundary between two plates that are moving apart?

Convergent: plates move into one another.Divergent: plates move apart.Transform: plates move sideways in relation to each other.

Do Plates move together or apart at mid ocean ridges?

Mid Ocean ridges separate the plates and create new seafloor. Places where plates converge and disappear into the abyss are called trenches. The Marianas Trench is the deepest trench in the world.


Mid ocean ridges form where tectonic plates do what?

Mid-ocean ridges form where tectonic plates diverge, or move apart. This process allows magma from the mantle to rise to the surface, creating new oceanic crust as it cools and solidifies. The continuous movement of the plates at these ridges contributes to seafloor spreading and the dynamic nature of the Earth's lithosphere.


Why do plates move away from the mid ocean ridges?

Plates move away from mid-ocean ridges due to the process of seafloor spreading, which occurs as magma rises from the mantle at the ridge, creating new oceanic crust. As this new crust forms, it pushes the older crust away from the ridge, causing tectonic plates to diverge. This movement is driven by convection currents in the mantle, which create forces that pull the plates apart. Additionally, the cooling and sinking of the oceanic lithosphere further contribute to the movement of plates away from the ridges.


What causes oceanic ridges?

Oceanic ridges are caused by the divergent movement of tectonic plates. As the plates move apart, magma rises from the Earth's mantle to fill the gap, creating new oceanic crust. This process is known as seafloor spreading.
