When the plates are moving apart.
Mid-ocean ridges are divergent plate boundaries where new oceanic crust forms as tectonic plates move apart. At these boundaries, magma rises from the mantle, cooling and solidifying to create new crust.
New Earth's crust is added at divergent plate boundaries, where tectonic plates move away from each other. At these boundaries, molten rock rises from the mantle and solidifies, creating new crust. A prime example of this is the Mid-Atlantic Ridge.

Volcanoes primarily form at tectonic plate boundaries, particularly at divergent and convergent boundaries. At divergent boundaries, tectonic plates move apart, allowing magma to rise and create new crust, often seen in mid-ocean ridges. At convergent boundaries, one plate subducts beneath another, leading to melting and volcanic activity. Therefore, while volcanoes can form at various plate boundaries, they do not always form on a single type of plate.

Volcanoes can form at divergent plate boundaries, where tectonic plates move apart, allowing magma to rise and create new crust, as seen in mid-ocean ridges. They can also form at convergent plate boundaries, where one plate subducts beneath another, leading to melting of the subducted plate and the formation of magma, which can result in volcanic eruptions, as observed in the Pacific Ring of Fire.
New crust is not formed at conservative plate boundaries. Instead, these boundaries involve plates sliding past each other horizontally without any creation or destruction of crust. This movement can cause earthquakes as the plates interact.
At diverging plate boundaries, new oceanic crust forms through seafloor spreading. Magma rises to the surface and solidifies, creating mid-ocean ridges. As the plates move apart, they create new oceanic crust, which can lead to the formation of rift valleys.
Most volcanoes form at either convergent or divergent plate boundaries. Volcanoes at convergent plate boundaries form when one plate slides under another, taking seawater with it. This causes the rock in the mantle to melt as the melting point drops. This new magma can rise to form volcanoes.At divergent plate boundaries the crust is thing, which lowers pressure on the mantle, causing some material to melt.
Divergent plate boundary.
Igneous rock can form at divergent plate boundaries where tectonic plates move apart and create new oceanic crust through seafloor spreading. It can also form at convergent plate boundaries where one plate subducts beneath another, leading to melting of the subducted crust and the formation of volcanic arcs. Lastly, igneous rock can be found at hot spot locations where magma rises from deep within the mantle to create volcanic islands or seamounts.
Material is only created at divergent plate boundaries, where tectonic plates move away from each other, allowing magma from the mantle to rise and solidify to form new crust. This process is known as seafloor spreading, leading to the creation of new oceanic crust.
