It is a constructive activity that takes place at
the mid-ocean ridge. The mid-ocean ridge is an
area where new crusts are created due to the
spliting apart of lithospheric plates. This process
is often known as sea-floor spreading and it
occurs at divergent boundaries of oceanic
lithospheric plates. Here the old plates spreads
apart moving away at opposite direction from
one another, as they move they give space for
new plates or crust to be created by refilling the
gaps with magmatic materials that rises from
within the asthenospheric layer of the mantle. As
this molten uptrust reaches water they cool and
solidify and become a new ocean-floor, these re-
born oceanic lithosphere are relatively denser
than the older ones.

∙ 9y agoThe tectonic process that takes place along mid-ocean ridges is called seafloor spreading. The mid-ocean ridge is formed when magma rises up to the surface at a divergent boundary. The oceanic plates on either side of the ridge are pushed apart as the magma flows in and this causes the seafloor to spread.

Where is there a divergent boundary?
Where two tectonic plates are moving farther away from each other, like at the Great Rift Valley in Africa.
Hardens to form new rock at mid-ocean ridges?
Sea- Floor Spreading molten material erupts through the valley that runs along the center of some mid-ocean ridges. This material hardens to form the rock of the ocean floor. Mid-ocean ridges an undersea mountain chain where new ocean floor is produced.
Volcanoes that form along mid-ocean ridges occur at?
mid ocean ridges form along, underwater mountain ranges that sometimes have a rift valley down their center( 6th grade answer)
Where is the rate of geothermal heat flow the greatest?
Along mid-ocean ridges.
What seafloor feature can be found along the rifts in the mid ocean ridges?
hydrothermal vents
Are mid-ocean ridges located mostly along coastlines?
No, mid-ocean ridges are not located mostly along coastlines. Mid-ocean ridges are underwater mountain ranges that form where tectonic plates are pulling apart. They are located in the middle of the ocean and can extend for thousands of kilometers.
Why are tilted blocks of rock common along mid-ocean ridges?
Plates move apart at these tectonic plate boundaries.
How do mid-ocean ridges work?
Two tectonic plates move apart, allowing for geologic activity along the boundary that slowly build a ridgeline along the bottom of the ocean.
What happens when new basalt forms along mid ocean ridges?
Magma that has bubbled up through the crack in the Earth's surface.
What are the medial ridges along the sacrum called?
The medial ridges along the sacrum are called the sacral crest. It is a series of tubercles that represent the processes of the sacral vertebrae.

What generally form ridges along the edges of glaciers?
Moraines
Elevated ridges along the flood plain are known as?
Leeves
Where do earthquakes volcanoes and mountains occur along?
Along the tectonic plate boundaries.
Earthquakes occur most often along the?
Earthquakes occur most often along the boundaries of tectonic plates.
