The mid-ocean ridge is the Earth's longest continuous mountain range, approximately 55-65 thousand kilometers long and bilaterally divided by a valley called a rift. The mid-ocean ridge is a volcanic feature caused by the spreading apart of oceanic plates as part of plate tectonics. The sea floor at the ridges are uplifted by rising magma. The rising magma is part of a process of heat transfer from the interior of the Earth to the surface known as a convection current. As the rising magma cools, it forms new crust which becomes part of the ridge. Therefore, the ridge is composed of basalt and gabbro, and is among the most recent of geologic age crustal rock. :)
What else can I help you with?
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.
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.
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
What is the difference between a rift valley and a mid ocean ridge and what kinds of boundaries do they form at?
A rift valley is a large depression where tectonic plates are moving apart, creating a gap in the Earth's crust. This forms at divergent boundaries, where plates move away from each other. A mid-ocean ridge is an underwater mountain range formed by the divergence of tectonic plates. They also form at divergent boundaries, specifically at oceanic spreading centers.
What living things live near the midocean ridge?
Living things that can be found near the mid-ocean ridge include tube worms, deep-sea fish, octopuses, and certain types of bacteria that thrive in the extreme conditions of the deep sea. These organisms have adapted to the high pressure, darkness, and volcanic activity in this unique environment.

When was MidOcean Partners created?
MidOcean Partners was created in 2003.
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
Which two tectonic plates are separated by the midocean ridge?
The mid ocean ridge separates many plates, not just two. In the Atlantic Ocean it separates the Eurasian and African plates from the North American Plate and the African Plate from the South American Plate. In the Indian Ocean it separates the African Plate from the Antarctic, Australian, Indian Plates and the Australian Plate from the Antarctic Plate. In the Red Sea it separates the African Plate from the Arabian Plate. In the Pacific Ocean it separates the Pacific Plate from the Antarctic, Nazca, Cocos, and Juan de Fuca Plates and the Nazca Plate from the Cocos and Antarctic Plates.
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
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.
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 midocean ridges offset the most by faults?
At transform faults or transform zones.
How are ridge and slab pull related to convection in Earths mantle?
they are related because they all have to do with the oceanic lithosphere.The convection causes the lithosphere to move sideways and away from the midocean ridges.The ridge push makes the oceanic lithosphere slide downhill under the force of gravity. The slab pull:the old lithosphere is denser than asthenosphere so, the edge of the tectonic plates that contains oceanic lithosphere sinks and plls the rest of the tectonic plate.
