How do the mantle's convection currents move to form a mid-ocean ridge?

The mantle's convection currents move in the mantle in the form of magma which creates the mid-ocean ridge. Mid-ocean ridges are found in every ocean in the world and when the currents erupt as lava the eventually cool and create a crust.

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 are the two main causes for Harry Hess' mid ocean ridge?
it is formed from convection currents.
What are the three processes that cause tectonic plates to move?
Three processes that contribute to the motion of tectonic plates are convection currents, ridge push, and slab pull. Convection currents is when the mantle rises, cools, sinks and heats, then rises and repeats the cycle. Ridge push is a gravitational force that causes a plate to move. Slab pull is the movement of tectonic plate lithosphere due to convection currents in the asthenosphere.
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 causes the oceanic lithosphere to move away from the mid-ocean ridge?
it is caused by convection currents

Where do you find convection currents?
Convection currents occur in the asthenosphere.

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.

What are convection currents in a mantle?
The asthenosphere is the layer of the Earth directly below the brittle lithosphere, made of solid rock with a small percentage of melt, which is under tremendous pressure and temperature conditions. It performs and moves in a ductile fashion (highly viscous) even though it is considered rock, and does not break while under stress, but can move due to convection currents of heat arising from Earth's interior.
What are 3 forces that causes tectonic plates to move?
This will be in detail for your information. 3 driving forces of plate motion...one plate moves underneath the other or a continental collision (if the 2... cause the gravitational sliding of lithosphere plates away from them...
