What happened at divergent boundaries?
divergent boundaries happen when 2 plates move apart or divide
When plates pull apart what often fills the void?
LavaAt divergent boundaries when plates pull apart magma rises up and fills the void. Convection cells in the mantle provide the magma which rises up at the divergent boundaries.
How are oceanic ridges form?
divergent boundaries
Name types of plate boundarys found when two plates separate?
These are called divergent plate boundaries marked by ridges, caused by the uplift of crust by rising magma, on either side of a rift valley, where the magma fills in the gap left by the spreading ridges.
What forms when magma forces itself across rock layers?
Magma fills the gap between plates at DIVERGENT boundaries.
How are convergent boundaries different from divergent boundries?
convergent boundaries collide but divergent boundaries move away from each other.
How do valcanoes form at divergent plate boundaries?
Beneath the Earth's crust is a lot of magma. Thus as the plates pull apart, it leaves a gap through which the magma can travel and erupt as lava. For example at the Mid Atlantic Ridge, there are divergent plate boundaries. The 'gap' between the divorcing plates allows magma to boil through, building up the ridge in the process.
What is a mountain chain at a divergent boundaries called?
mountain chains at divergent boundaries are called
Ocean ridges are formed by what boundaries?
Divergent boundaries form ocean ridges.
Is subduction common at divergent plate boundaries?
Subduction doesnt occur at divergent boundaries, but rather they are found at convergent boundaries.
What are plate boundaries that move away form each other?
divergent
What happens divergent boundaries?
divergent boundaries happen when 2 plates move apart or divide
