Hot material is constantly welling up from beneath the crust via convection and forming new crust as it cools. The continuous formation of new crust pushes the old crust outward from the mid-ocean ridges.

Do Plates move together or apart at mid ocean ridges?
Mid Ocean ridges separate the plates and create new seafloor. Places where plates converge and disappear into the abyss are called trenches. The Marianas Trench is the deepest trench in the world.
What is convection and how does it cause plates to move?
What is convection and how does it cause plates to move? What are the consequences of convection in the mantle?
Divergent plates move from each other This causes to form as well as mid-ocean ridges?
away, rifts
Do convection currents in the oceans cause tectonic plates to move?
No, convection currents in the upper mantle cause tectonic plates to move.
Why do oceanic rises and oceanic ridges exist?
They are located at spreading centers in the middle of the ocean. As tectonic plates move apart, magma fills it in and creates ridges and rises which are essentially mountain chains.
What is located in midocean ridges?
The Mid-Atlantic Ridge is found on the ocean floor in the middle of the Atlantic Ocean.
What happens when earth's plate move?
when the earths plates move we either have earthquakes, tsunamis, and we get ridges and trenches.

Where would two plates move apart at mid-oceanic ridges?
at a divergent plate boundary

What is convection and how does it cause plates to move? What are the consequences of convection in the mantle?
What occurs when two tectonics plates move away from each other?
mid-ocean ridges and volcanoes
What direction do plates move in relation to ridges?
Depends on the type of plate boundary, at a mid-ocean ridge the plates move away from eachother. Ridges can also occur as a result of plate collision where the top layer of lithosphere is scraped off the subducted slab, this is called an accretionary prism.
Do convection current in oceans cause tectonic plates to move?
No, convection currents in the upper mantle cause tectonic plates to move.

Why are tilted blocks of rock common along mid-ocean ridges?
Plates move apart at these tectonic plate boundaries.
Why do oceanic rises and oceanic ridges exist?
They are located at spreading centers in the middle of the ocean. As tectonic plates move apart, magma fills it in and creates ridges and rises which are essentially mountain chains.
