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 Spreading
Magma rises from magma chambers at the rifts in the sea floor. Cooling and hardening then occurs.
it has to touch plate boundaries to push away from each other

Plates do not cause volcanoes. Volcanoes generally form at the boundaries between plates. They form at convergent and divergent boundaries.
Underwater volcanoes and mountains can form at both convergent and divergent boundaries.

In plate tectonics, divergent boundaries occur when plates pull apart. On land, divergent boundaries form rifts or valleys. More commonly, divergent boundaries in the ocean occur and cause mid-oceanic ridges. Divergent boundaries can also form volcanoes when the plates separate enough to allow molten lava to seep out, harden, and eventually form islands.
Volcanoes can form at convergent boundaries, divergent boundaries, and at hot spots away from any plate boundary.
They are similar because they both form volcanoes and earthquakes.
