HomeWhat type of magmatic activity is characteristic of mid oceanic ridges?
At mid-oceanic ridges, plates are pulled apart in two separate directions. This creates a gap (rift valley), allowing for warm, buoyant magma to rise to the surface and cool. As the magma cools, it creates ridges along the rift valleys. The elevation is caused by the excess amount of newly created, less dense oceanic crust. This crust occupies more volume, which causes it to be higher up than the surrounding, older crust.

Seafloor spreading. This process includes the splitting of oceanic crust, pushing it aside and building new crust in the middle by magmatic activity.
I think just a oceanic ridges
Along the mid oceanic ridges (sites of crustal generation)
No. Mid oceanic ridges are the places where new oceanic crust are forming.
Oceanic lithosphere is always formed at active mid-ocean ridges and rises.
When oceanic and oceanic plates diverge it creates mid ocean ridges!
Ridges of buoyant oceanic crust form at diverging oceanic plate boundaries.
New oceanic crust is created at the mid-oceanic ridges, a divergent plate boundary.
Generally, magmatic material rises through sea floor ridges to form new crust in the oceans. A small amount is released through volcanic activity.
In the main along the mid oceanic ridges and along oceanic trenches.
Magmatic upsurge from within the earths crust, and plumes.
At the oceanic ridges the age of igneous basalt rocks is approximately zero (as that is where they formed) and the rocks get older the farther away. The ages of sedimentary and metamorphic rocks does not correlate reliably with distance from the oceanic ridges like the ages of igneous rocks, because they can form anywhere not mainly at oceanic ridges. Igneous granite rocks are generally formed around continental volcanos not oceanic ridges.
No. New oceanic crust forms at mid ocean ridges. Oceanic crust sinks into the ocean at subduction zones, which are usually marked by ocean trenches.
The youngest oceanic crust can be found near the mid-ocean ridges.
Oceanic-oceanic plate divergence, such as that occurring at the mid-ocean ridges.
Oceanic divergent plate boundaries. Oceanic ridges and oceanic trenches. The ridges are are zones where oceanic crust is emerging to the surface and is the source of sea floor spreading, and oceanic trenches form near continental margins where the sea floor is subducted beneath the continent.
At the mid-ocean ridges.
oceanic lithosphere sinks at subduction zones but not at mid ocean ridges because at subduction zones the oceanic lithosphere is subducted, or sinks, under another plate. Oceanic Lithosphere sinks at subduction zones which are usually at convergent boundaries, but at mid-ocean ridges the plates are actually separating not coming together
If you mean "what" forms at mid-ocean ridges, the answer is new oceanic crust.
Ridges are elevated because the rocks are hot.
Matching fossils in separated continents and the growth of oceanic crust at mid-oceanic ridges and destruction of oceanic crust at trenches.
They are located at spreading centers in the middle of the ocean. As tectonic plates move apart, magma fills it in and creates ridges and rises which are essentially mountain chains.

Yes. Mid Ocean Ridges create new oceanic crust.
In oceanic ridges and continental rift zones.
