Mountain range: A mountain range or hill range is a series of mountains or hills ranged in a line and connected by high ground.  A mountain system or mountain belt is a group of mountain ranges with similarity in form, structure and alignment that have arisen from the same cause, usually an orogeny.  Mountain ranges are formed by a variety of geological processes, but most of the significant ones on Earth are the result of plate tectonics.  Mountain ranges are also found on many planetary mass objects in the Solar System and are likely a feature of most terrestrial planets.

Undersea mountain range: Undersea mountain ranges are mountain ranges that are mostly or entirely underwater, and specifically under the surface of an ocean.  If originated from current tectonic forces, they are often referred to as a "mid-ocean ridge".  In contrast, if formed by past above-water volcanism, they are known as a "seamount chain".  The largest and best known undersea mountain range is a mid-ocean ridge, the Mid-Atlantic Ridge.  It has been observed that, "similar to those on land, the undersea mountain ranges are the loci of frequent volcanic and earthquake activity".
