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 else can I help you with?
What occurs when two tectonics plates move away from each other?
mid-ocean ridges and volcanoes
What direction do plates move in relation to ridges?
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 do plates do at divergent plate boundaries?
At divergent plate boundaries, plates move away from each other due to the upwelling of magma from the mantle. This process creates new oceanic crust as the plates separate. As the plates move apart, they create features such as mid-ocean ridges and rift valleys.
What type of plate movement causes mid ocean ridges and sea floor spreading?
Divergent plate boundary movement causes mid-ocean ridges and sea-floor spreading. This occurs when two tectonic plates move away from each other, creating new oceanic crust at the boundary. Magma rises to the surface, solidifies, and forms undersea mountain ranges known as mid-ocean ridges.
What happens the age of rock with distance from the mid ocean ridges?
The age of rock increases with distance from mid-ocean ridges. At the ridges, new oceanic crust is formed through volcanic activity, which is young. As the crust moves away from the ridges, it cools and becomes older. This process is known as seafloor spreading.
What occurs when two tectonics plates move away from each other?
mid-ocean ridges and volcanoes
Boundaries are often found at ocean ridges.?
Yes, ocean ridges are divergent plate boundaries where tectonic plates move away from each other. As the plates separate, molten rock rises from the mantle and solidifies to form new oceanic crust, creating the underwater mountain range characteristic of ocean ridges.
What direction do plates move in relation to ridges?
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.
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.
How do earths magnetic pole reversals provide evidence for plate tectonics?
Magnetic stripes can be seen as you move away from ocean ridges.
What type of boundry is mid ocean ridge?
The main boundary associated with mid-ocean ridges are divergent boundaries, because the plates move away from eachother, or "diverge".
Which type of boundary do mid-ocean ridges occur?
divergent
What forms at a mid ocean ridges?
A mid-ocean ridge is formed when two tectonic plates move away from each other and the opening left by them separating fills in with magma.
When two plates move away from each other it is called what boundary?
When two plates move away from each other it makes a falt line or a riffed. -bekahcboo

What type of plate movement causes mid ocean ridges and sea floor spreading?
Divergent plate boundary movement causes mid-ocean ridges and sea-floor spreading. This occurs when two tectonic plates move away from each other, creating new oceanic crust at the boundary. Magma rises to the surface, solidifies, and forms undersea mountain ranges known as mid-ocean ridges.
