How does magma form ay divergent boundaries?
Hot mantle rock rises to fill rift zones. When rock rises, a decrease in pressure causes hot mantle rock to melt and form magma.
How does magma form at convergent and divergent boundaries?
At divergent boundaries, two plates move apart from each other and the space that this creates is filled with new crustal material sourced from molten magma that forms below.
How do volcanoes form at divergent boundaries?
As the plates move away from each other at divergent boundaries, the lithosphere becomes thinner. A set of deep cracks form in the rift zone. The convection currents of the mantle can form a weak spot, and the heated, less dense magma rises up to fill the gap.Seafloor SpreadingMagma rises from magma chambers at the rifts in the sea floor. Cooling and hardening then occurs.
Do divergent plate boundaries produce volcanoes?

At divergent plate boundaries in the ocean magma rises and melts because of?
Because of a decrease in pressure.
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.

Why does melting occur at divergent plate boundaries?
Hot mantle rock rises where the plates are moving apart. This releases pressure on the mantle, which lowers its melting temperature. Lava erupts through long cracks in the ground, or fissures

At divergent plate boundaries in the ocean magma rises and melts because of?
Because of a decrease in pressure.
At a divergent boundary land is gained or lost?
At a divergent boundary, land is gained. Ocean ridges are prominent at divergent plate boundaries. Ocean ridges are areas of seafloor spreading. Seafloor spreading occurs as upwelling magma rises to the surface. This upwelling magma hardens and forms new seafloor.
When does convection occurs?
When a warm fluid rises and a cool fluid sinks.
Where is a volcano most likely to form?
Volcanoes are most likely to form along tectonic plate boundaries, such as convergent and divergent plate boundaries. Convergent boundaries occur when two plates collide, causing one plate to subduct beneath the other, creating volcanic activity. Divergent boundaries occur when two plates move apart, creating gaps where magma rises to the surface and forms volcanoes. Additionally, volcanoes can also form within hotspots, where a plume of hot magma rises through the Earth's mantle.
