If one tectonic plate starts to move away from another as they float on the asthenosphere, the movement can lead to a gap in the earth's crust, where magma bubbles up from below. This usually happens in the oceanic lithosphere (the bits of the lithosphere that are under the oceans).

WebMagma is created at mid-ocean ridges via decompression melting. Strong convection currents cause the solid asthenosphere to slowly flow beneath the lithosphere. The upper part of the lithosphere (crust) is a poor heat conductor, so the temperature remains about the same throughout the underlying mantle material.
