What a ridge push?
Ridge push is a gravitation force that causes a plate to move away from the crest of an ocean ridge, and into a subduction zone.
What is a ridge push?
Ridge push is a geological concept where the force of gravity causes oceanic lithosphere to move downhill from a mid-ocean ridge, pushing tectonic plates away from the ridge. This process contributes to plate motion along with other forces like slab pull and mantle convection.
What causes the oceanic lithosphere to move away from the mid-ocean ridge?
it is caused by convection currents
What landscape forms at a mid ocean ridge?
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.
What evntually happens to seafloor that is carried away from a mid-ocean ridge?
Seafloor continues to move away from the mid-ocean ridge and eventually comes into contact with another plate boundary. Ocean plates subduct underneath continental plates and are forced down into the lithosphere
How do magnetics stripes show the history of earths magnetics field?
as you move away from an ocean ridge the rocks get older
Why does the ocean floor spread apart at the ridge?
Because as tectonic plates move away from each other, the ocean floor spreads apart and fills the gap.
What happens to plates as they move away from the mid ocean ridge?
As plates move away from a mid-ocean ridge, new oceanic crust forms through volcanic activity. This process, known as seafloor spreading, leads to the creation of new oceanic crust and widens ocean basins. The older crust becomes cooler and denser as it moves away from the ridge.
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".
At a mid Ocean ridge how do the two tectonic plates move?
At a mid-ocean ridge, tectonic plates move apart from each other due to seafloor spreading. Magma rises up from the mantle, solidifies at the ridge, and forms new oceanic crust. This process pushes the plates away from each other, causing them to move in opposite directions.
What happens when you move roks away from the ocan ridge?
When rocks are moved away from the ocean ridge, the gap created is eventually filled by magma rising up from the mantle below. This process is known as seafloor spreading, where new oceanic crust is formed as magma solidifies and creates a new ocean floor. Over time, this continuous spreading and creation of new oceanic crust causes the ocean basin to widen.
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.
