Plates of the earth's crust are moving away from each other, forming an extensive system of fractures and faults.

What type of boundary occurs most at mid ocean ridge?
The mid-ocean ridge is formed along a divergent or constructive plate boundary between two plates of oceanic crust. A classic example is the Mid-Atlantic Ridge where the Eurasian and African Plates are moving away from the North and South American Plates.
Is the moving portion of earth's crust and upper mantle called a ridge?
Not quite. These are known as tectonic plates. A (mid ocean) ridge is a type of boundary between differing tectonic plates which are diverging or moving away from each other..
What type of boundary is found at a mid ocean ridge and what type of boundary is found at a trench?
Divergent - where two plates are moving away from one another. (Mid-ocean Ridge)Convergent - where two plates are moving towards one another. (Ocean Trench) found at both O/O converge and O/C converge.
What happens when you move roks away from the ocan ridge?
They increase in age and density, and decrease in temperature.
Does the fact that ocean crust is older the farther away it is from an ocean ridge support the theory of plate tectonics?
Yes. New ocean crust is being formed at the mid ocean ridges (MORs) resulting in the older crust being pushed farther away, moving the plates towards a subduction zone. MORs divide 2 plates.
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

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 happens to the old crust when new crust is made?
This question can be answered by looking at the Mid Ocean Ridge. Being a mostly divergent boundary, the oceanic plates are pulling away due to tensional stress. One would assume this would leave a deep ocean trench as the plates pull away. This is not the case. As the plates pull away, igneous material (usually basalt) is produced upwards and immediately fills the void left by the separating plates. This new magma is at the very center of the Mid Ocean Ridge. The older magma that had been produced in this same method are on either side of this new material. As the plates pull apart, the old material is pulled with it. Gravity also pulls these older materials downward and away from the higher Mid Ocean Ridge.
What happens at mid ocean ridges?
A mid-ocean ridge is a a long, seismically active submarine ridge system situated in the middle of an ocean basin and marking the site of the upwelling of magma associated with seafloor spreading.
What eventually happens to seafloor that is carried away from the mid ocean ridge?
its deposited somewhere else
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 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".
What type of boundary is found at a mid ocean ridge and what type of boundary is found at a trench?
Divergent - where two plates are moving away from one another. (Mid-ocean Ridge)Convergent - where two plates are moving towards one another. (Ocean Trench) found at both O/O converge and O/C converge.
