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

No, subduction is not common at divergent plate boundaries. Divergent plate boundaries are characterized by plates moving away from each other, which creates new oceanic crust. Subduction occurs at convergent plate boundaries where plates collide and one descends beneath the other.
Melting of the mantle at divergent plate boundaries is primarily caused by the decrease in pressure as the tectonic plates move apart. This reduction in pressure lowers the melting point of the mantle rock, allowing it to melt and form magma that can rise to the surface and create new crust. Magmatic activity at divergent boundaries is a key driver of seafloor spreading and plate tectonics.
Earthquakes can, and do, occur at divergent, convergent, and transform plate boundaries.
No, divergent plate boundaries can occur both on the ocean floor and on land. When they occur on the ocean floor, they create mid-ocean ridges, while on land they can create rift valleys.
Convergent, divergent, and, although not a plate boundary, they also occur from hotspots.
Volcanoes at divergent plate boundaries often occur along mid-ocean ridges, where tectonic plates are moving apart. As the plates separate, magma rises to the surface, creating underwater volcanic activity. These volcanic eruptions contribute to the formation of new oceanic crust.
The three main types of plate boundaries are divergent, convergent, and transform. Divergent boundaries occur where plates move apart, creating new crust. Convergent boundaries occur where plates collide and can result in subduction zones or mountain formation. Transform boundaries occur where plates slide past each other horizontally.
