Official names for these features have only been announced very recently, as Titan's surface was virtually unknown before the arrival of the Cassini probe.
Albedo features on Titan are named after sacred or enchanted places in world mythologies and literature.
Because the exact nature of many surface features remain mysterious, a number of features have not yet received formal names and are known by nicknames.

 Cassini-Huygens: News-Features-the Story of Saturn
Titan is of great interest to scientists because it is the only moon in the solar system known to have clouds and a mysterious, thick, planet-like atmosphere.
Because of the extremely cold temperatures typical of celestial bodies that are that far away from the sun, the structure of Titan's chemical atmosphere is in a state of deep freeze.
Titan's thick cloudy atmosphere is mostly nitrogen, like Earth's, but may contain much higher percentages of "smog-like" chemicals such as methane and ethane.

 Volcano - Biocrawler   (Site not responding. Last check: 2007-10-30)
A volcano is a geological landform (usually a mountain) where magma (rock of the earth's interior made molten or liquid by high pressure and temperature) erupts through the surface of the planet.
See the list of geological features on Io for a list of named volcanoes on the moon.
Volcanic cones are usually smaller features composed of loose ash and cinder, with occasional masses of stone which have been tossed violently into the air by the eruptive forces (and are thus called ejecta).

 CHAPTER 5: PLANETARY GEOLOGY: Manual of Remote Sensing
Geologic histories of planetary surfaces are often documented in the form of geologic maps (compiled at various scales dependent on the available data and detail to be illustrated) which portray the three-dimensional surface units that comprise a planetary surface and indicate their relative stratigraphic positions.
Geologic information was difficult to extract from drawings and photographs having spatial resolutions on the order of hundreds of kilometers, and observations by Schiaparelli, Lowell, Antoniadi, and others demonstrated that the interpretation of features observed on Mars was controversial and often highly subjective (Sheehan, 1988).
Geologic study of Mars over the past decade has concentrated on the continued refinement and analysis of the Viking imaging data in preparation for the next wave of spacecraft exploration to be carried out by the Mars Global Surveyor orbiter and Mars Pathfinder lander missions in 1997-1999.

Although geological activity is a promising sign for a planet when being considered as a site for life [and you should be able to explain why this is], Io's extreme volcanic activity precludes life there.

"Titan is perhaps the most Earth-like place in the Solar System other than Earth, in terms of the balance of processes," says Jonathan Lunine, of the University of Arizona, who is an interdisciplinary scientist for Cassini-Huygens.
Evidence also suggests Titan is constantly being resurfaced by a fluid mixture of water and ammonia spewed out by volcanoes and hot springs, explaining why Titan is not littered with impact craters like its neighbours A surface feature called Ganesa Macula may show just such a flow emanating from a volcanic crater.

Titan synchronous orbit trajectories will allow about 35 flybys of Titan and targeted flybys of Iapetus, Dione and Enceladus.
One of the most intriguing aspects of Titan is the possibility that its surface may be covered in part with lakes of liquid hydrocarbons that result from photochemical processes in its upper atmosphere.
The integrated lander payload includes a surface stereo imager with Mars Pathfinder heritage; a meteorology package; an instrumented robotic arm for sample acquisition, soil manipulation and closeup imaging of the surface and subsurface; and the thermal and evolved gas analysis experiment for determining the nature and abundance of volatile material in the Martian soil.

 Dione (moon)
Dione is composed primarily of water ice, but as the densest of Saturn's moons (aside from Titan, whose density is increased by gravitational compression) it must have a considerable fraction of denser material like silicate rock in its interior.
One theory was that shortly after its formation Dione was geologically active, and some process such as ice volcanism resurfaced much of its surface, with the streaks forming from eruptions along cracks in Dione's surface that fell back to the surface as snow or ash.
Like Callisto, Dione's craters lack the high relief features seen on the Moon and Mercury; this is probably due to slumping of the weak icy crust over geologic time.

It ranges from a persistent drizzle that keeps the surface of Saturn's largest moon -- which has geological features similar to Earth -- damp to fierce storms that could produce huge droplets.
Information from the probe showed Titan, which is larger than the planet Mercury, is cold and windy with a dense atmosphere of methane and nitrogen.
In a separate report in the journal researchers from Spain did a modeling study of Titan's atmosphere which suggested clouds over the south pole would produce fierce storms that would pound the surface and could help explain the formation of its river valleys.
