∙ 12y agoThe ridge was formed by tectonic plate movement wich forces lava through the created cracks and when the lava cools it forms the ridge.

Where is active seafloor spreading occurring today?
At any divergent plate margin: The Mid-Atlantic Ridge The boundary between the African Plate and Arabian Plate (the Red Sea) Great Rift Valley West Antarctic Rift East Pacific Rise Pacific-Antarctic Ridge Galapagos Rise Gakkel Ridge
Where are the youngest rocks found on the seafloor?
Near fault lines, it is there that rocks are created by the rubbing or colliding of the tectonic plates. Rocks could also be made by volcanoes via the cooling of magma and lava. The closer to the fault line you are the newer the rock and the farther away you get the older the rock becomes.
What are the names of the two plates that separate to form the North Atlantic Ridge?
The North American and Eurasian plates separate to form the North Atlantic Ridge.
Is new oceanic crust formed at a mid-ocean ridge?
The answer to that question is the following:=Magma rises toward the surface and solidifies=
Location in ocean basin where new ocean floor is formed?
This sounds like the mid ocean ridge. This is where the plates are moving apart and magma wells up to form new rock.
Where do midocean ridges intersect the landmasses?
Midocean ridges are areas where continents broke apart. Midocean ridges are closest to the landmasses in younger oceans. One example where a midocean ridge intersected a landmass is the Arabian sea, which was formed by the pulling apart of the Arabian Peninsula and Africa.
What is the difference between a rift valley and a mid ocean ridge and what kinds of boundaries do they form at?
a rift valleyis a dip in the ocean floor a mid ocean ridge is a mountain chain formed on the ocean floor . Rift valley - divergent boundary MidOcean Ridge Convergent Boundary
Is the Mid-Oceanic Ridge in the middle of the Atlantic Ocean?
One of the midocean ridges is, but others are in other oceans, seas, and bays.
The movement of the ocean floor on either side of a midocean ridge is best known as?
it is known as sea floor spreading. this is when the oceanic plates diverge or move apart which causes the magma from the mantle to rise forming new sea floor.
Do Ocean sediments become younger or older away from midocean ridges?
Older, as it moves away from the mid-ocean ridge the sediment gets thicker and older
When was MidOcean Partners created?
MidOcean Partners was created in 2003.
What are the differences between ocean ridge and seamount?
The midocean ridges are the spreading centers where the plates are moving apart. The seamounts are extinct volcanos produced as the plate passed over a mantle hotspot.
What is a force that is causing the plates to move at a midocean ridge?
friction - convection currents in the mantle drag the plates away from the hot rising zone below the ridgegravity - gravity pulls down on the cold dense plate being subducted under the continent, dragging the plate away from the ridge
Where is active seafloor spreading occurring today?
At any divergent plate margin: The Mid-Atlantic Ridge The boundary between the African Plate and Arabian Plate (the Red Sea) Great Rift Valley West Antarctic Rift East Pacific Rise Pacific-Antarctic Ridge Galapagos Rise Gakkel Ridge
How does sea-floor spreading occur?
as convection currents cause more magma to rise the new magma forces apart the hardened material and like a conveyer belt continuously pushes older rocks aside
How are volcanoes created at the Mid-Atlantic ridge?
Volcanoes are created in the Mid-Atlantic ridge from plates in the ocean floor. The plates shift causing new magma to be able to be released from the earth which in return form the new volcano.
How are volcanos created at the Mid-Atlantic Ridge?
Volcanoes are created in the Mid-Atlantic ridge from plates in the ocean floor. The plates shift causing new magma to be able to be released from the earth which in return form the new volcano.
