No, mid-oceanic ridges are not collisional; they are divergent boundaries where tectonic plates are moving apart. At these ridges, magma rises from the mantle to create new oceanic crust as the plates separate. This process is responsible for the formation of new ocean floor and is characterized by volcanic activity and seismic events. In contrast, collisional boundaries occur where plates converge, leading to features like mountain ranges and subduction zones.

Does granitic crust form at the mid oceanic ridge?
Granitic crust does not form at the mid-oceanic ridge. Rather another type of igneous rock Basalt is formed at the Mid-Oceanic ridge. Both are silicate rocks and have a high oxygen and silica content. The difference is that Granite is formed intrusively, that is within the Earth's crust. Basalt is extrusive, that is it is formed above the Earth's surface, such as at the bottom of the ocean at the Mid-Oceanic ridge.
What does the mid oceanic ridge do in the movement of the plates?
The mid-oceanic ridge is a divergent tectonic plate boundary where new oceanic crust is formed as magma rises from the mantle. As tectonic plates move apart, the ridge facilitates the continuous creation of new material, pushing older crust away from the ridge. This process drives seafloor spreading, contributing to the movement of tectonic plates and influencing geological activities like earthquakes and volcanic eruptions. Overall, the mid-oceanic ridge plays a crucial role in the dynamic cycling of Earth's lithosphere.
What type of volcanism occurs underwater along the mid-oceanic ridge?
Rift volcanism.
Is the mid ocean ridge the location of the oldest ocean floor?
No, the mid-ocean ridge is actually where new oceanic crust is formed through volcanic activity. As the crust moves away from the ridge, it becomes older. The oldest oceanic crust is found near the edges of the ocean basins.
Does subduction occur at the mid ocean ridge?
No, the Mid Atlantic Ridge is where the two plates are diverging, which creates more oceanic floor.
Are the plates at both sides of Mid-Atlantic Ridge continental or oceanic?
Plates on either side of the Mid-Atlantic Ridge are oceanic plates.
What is a chain of mountains under the water called?
Mid-ocean ridge or mid-oceanic ridge
Is oceanic crust near the mid-ocean ridge older thean oceanic crust farther away from the ridge?
Its oceanic crust
Where are the youngest rock on the ocean floor found?
Near the mid-Atlantic ridge.
Where is oceanic and continental plates?
at the mid-ocean ridge
Why does the Earth's size remains the same despite of what is happening at the mid-oceanic ridge?
An equal amount of oceanic crust is being subducted at the convergent plate boundaries as is being created at the mid-oceanic ridge.
Is the oceanic crust near a mid-ocean ridge thicker or thinner than the oceanic crust away from the mid-ocean ridge?
The Oceanic Crust close to the Mid Ocean Ridge is thinner than that Oceanic Crust far away from the ridge. This is due to tensional forces, as a result of crustal expansion and rock fracturing during the formation of the ridge.the oceanic crust is thinner
Is ocean crust formed at a mid ocean ridge?
Yes, the process that creates oceanic crust on a mid-ocean ridge is called "seafloor spreading". seafloor spreading creates a new oceanic crust that forms on the mid-ocean ridge.
Is new oceanic crust formed at mid-ocean ridges?
Yes, the process that creates oceanic crust on a mid-ocean ridge is called "seafloor spreading". seafloor spreading creates a new oceanic crust that forms on the mid-ocean ridge.
Oceanic crust near the mid ocean ridge is younger than oceanic crust farther away from the ridge?
hit the books!!
What might you find at the mid ocean ridge?

What is created at a mid ocean ridge?
New oceanic crust.
