What forms when 2 oceanic plates move apart?
Some move away from each other and create massive trenches normally in the sea bed, for example the Mariana Trench - 10,998 m.
What happens when 2 plates move away from one another?
A rift is created in the Earth's crust. An outstanding example of this is the Great Rift Valley in Africa.
Does the tectonic plates move about?
yes the plates can move slowly
Describe the process of subduction at a deep ocean trench?
Where one plate is pushed downward beneath another plate into the underlying mantle when plates move towards each other..=)
Where do convergent plates move?
Convergent plates move toward one another
What happens when two oceanic plates move?
When the plates separate water fills in the cracks, this leaves trenches ie. (Mariana Trench) the deepest part of the ocean approx. 7mil below sea level.

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.

Why did the Volcanic Marianas Islands form west of the Marianas Trench?
The Volcanic Marianas Islands form west of the Marianas trench because plates are formed by underwater volcanoes which will move gently to the west.
What happens at a covergent boundary?
two plates move togetheran ocean trench forms ;0 apex the first one is wrong
What is it called when the site where plates move towards each other collide with the denser plate plunging beneath the other forming a deep trench?
Subduction zone.
Why are Oceanic trenches found only in association with subduction zones?
The trenches are evidence that one of the colliding plates is moving beneath the other. As the two plates move together, one gets pushed below the other. The place where this sinking/bucking occurs creates a deep trench. The deepest of which is Marianas trench about 7 miles deep.
The type of plate boundary where plates move apart resulting in upwelling of material from the mantle to create new sea-floor is known as what plate boundary?
Mid-Atlantic Trench

Why do mountains move?
Mountains move by the plates under the earth moving. When plates move, often tsunamis and earthquakes happen. Mountains move 1 cm per year when the plates move!
