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. :)

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 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
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 living things live near the midocean ridge?
Thermophiles, they live at the deep sea smokers and require heat to carry out their biological functions instead of sunlight.

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
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.
What living things live near the midocean ridge?
Thermophiles, they live at the deep sea smokers and require heat to carry out their biological functions instead of sunlight.
What is located in midocean ridges?
The Mid-Atlantic Ridge is found on the ocean floor in the middle of the Atlantic Ocean.
Where are the midocean ridges offset the most by faults?
At transform faults or transform zones.
