Galaxies are categorized into three main types: Spiral galaxies have both old and young stars and interstellar matter. Elliptical galaxies are spheroidal systems with primarily old stars and little interstellar matter. Irregular galaxies are disorganized and contain both old and young stars.
Galaxies can be broadly categorized into three types: Spiral, Elliptical, and Irregular galaxies. Spiral galaxies, like our own Milky Way, contain both old and young stars as well as interstellar matter, with masses typically in the range of 10⁹ to 10¹² Msun. They have a central bulge surrounded by spiral arms, where star formation is usually quite active.
Elliptical galaxies are spheroidal or slightly elongated systems that predominantly consist of old stars with very little interstellar matter. These galaxies can vary greatly in size, from giant ellipticals which are often more massive than any spiral galaxy, to dwarf ellipticals with masses of only about 10⁶ Msun.
Irregular galaxies, as the name implies, lack the regular, symmetric appearance of spiral or elliptical galaxies. Often lower in mass and luminosity than spiral galaxies, they have a less organized appearance and may contain a mix of old and young stars.

Volcanic eruptions linked to continental shifting generally occur at convergent and divergent boundaries of tectonic plates. These may lead to the formation of volcanic mountain ranges or rifts respectively.
Volcanic eruptions that occur as a result of continental shifting, a process also known as plate tectonics, are typically found at plate boundaries. Specifically, they are most common at convergent boundaries and divergent boundaries. At convergent boundaries, one tectonic plate is forced underneath another in a process called subduction, often leading to the creation of a volcanic mountain range.
Divergent boundaries, on the other hand, are places where tectonic plates are moving apart, creating a rift that allows magma to rise to the surface and form volcanoes.
