Information:  - In linguistics, a suffix (also sometimes termed postfix or ending) is an affix which is placed after the stem of a word. Common examples are case endings, which indicate the grammatical case of nouns or adjectives, and verb endings, which form the conjugation of verbs.  - Ancient Greek includes the forms of Greek used in ancient Greece and the ancient world from around the 9th century BC to the 6th century AD. It is often roughly divided into the Archaic period (9th to 6th centuries BC), Classical period (5th and 4th centuries BC), and Hellenistic period (3rd century BC to the 6th century AD). It is antedated in the second millennium BC by Mycenaean Greek.  - A terrestrial planet, telluric planet, or rocky planet is a planet that is composed primarily of silicate rocks or metals. Within the Solar System, the terrestrial planets are the inner planets closest to the Sun, i.e. Mercury, Venus, Earth, and Mars. The terms "terrestrial planet" and "telluric planet" are derived from Latin words for Earth ("Terra" and "Tellus"), as these planets are, in terms of composition, "Earth-like".  - Earth, otherwise known as the world, is the third planet from the Sun and the only object in the Universe known to harbor life. It is the densest planet in the Solar System and the largest of the four terrestrial planets.  - The geology of the Moon (sometimes called selenology, although the latter term can refer more generally to "lunar science") is quite different from that of Earth. The Moon lacks a significant atmosphere, which eliminates erosion due to weather; it does not have any form of plate tectonics, it has a lower gravity, and because of its small size, it cooled more rapidly. The complex geomorphology of the lunar surface has been formed by a combination of processes, especially impact cratering and volcanism. The Moon is a differentiated body, with a crust, mantle, and core.  - Earth science or geoscience is a widely embraced term for the fields of science related to the planet Earth. Earth science can be considered to be a branch of planetary science, but with a much older history. There are both reductionist and holistic approaches to Earth sciences. The Earth sciences can include the study of geology, the lithosphere, and the large-scale structure of the Earth's interior, as well as the atmosphere, hydrosphere, and biosphere. Typically, Earth scientists use tools from geography, chronology, physics, chemistry, biology, and mathematics to build a quantitative understanding of how the Earth system works and evolves.  - Petrology ( from the Greek  , pétra , `` rock '' and  , logos , `` subject matter '' , see - logy ) is the branch of geology that studies the origin , composition , distribution and structure of rocks . Lithology was once approximately synonymous with petrography , but in current usage , lithology focuses on macroscopic hand - sample or outcrop - scale description of rocks while petrography is the speciality that deals with microscopic details . In the petroleum industry , lithology , or more specifically mud logging , is the graphic representation of geological formations being drilled through , and drawn on a log called a mud log . As the cuttings are circulated out of the borehole they are sampled , examined ( typically under a 10 × microscope ) and tested chemically when needed .  - Geology (from the Ancient Greek , "g", i.e. "earth" and -o, "-logia", i.e. "study of, discourse") is an earth science comprising the study of solid Earth, the rocks of which it is composed, and the processes by which they change. Geology can also refer generally to the study of the solid features of any terrestrial planet (such as the geology of the Moon or Mars).  - -logy is a suffix in the English language, used with words originally adapted from Ancient Greek ending in ("-logia"). The earliest English examples were anglicizations of the French "-logie", which was in turn inherited from the Latin "-logia". The suffix became productive in English from the 18th century, allowing the formation of new terms with no Latin or Greek precedent.

Answer: petrology


Information:  - The UCI ProTour was a series of road bicycle races in Europe, Australia and Canada organised by the UCI (International Cycling Union). Created by Hein Verbruggen, former president of the UCI, it comprises a number of 'ProTour' cycling teams, each of whom are required to compete in every round of the series. It was initially the basis of a season long competition for rankings points, created for 2005 to replace the UCI Road World Cup series, which ended at the end of the 2004 season (although the World Cup did not include any stage races). The ProTour was the subject of continuing disputes involving the UCI, cycling teams, and the organizers of the world's most prominent bicycle races (most notably, the Grand Tours), and in 2009 and 2010 the ranking element of the ProTour was superseded by the UCI World Ranking. For 2011, the ProTour and World Ranking were fully merged into the UCI World Tour. ProTour status for teams  relabelled UCI ProTeams  will continue as the highest level of registration, and will carry the right and obligation to participate in all World Tour races.  - Ian Stannard ( born 25 May 1987 ) is an English track and road racing cyclist for UCI ProTour team Team Sky . He is known for his stamina and is a force on flat roads .  - A cycling team is a group of cyclists who join a team or are acquired and train together to compete in bicycle races whether amateur or professional  and the supporting personnel. Cycling teams are most important in road bicycle racing, which is a team sport, but collaboration between team members is also important in track cycling and cyclo-cross.  - The UCI World Tour (20092010: "UCI World Ranking") is the premier annual male elite road cycling tour. It refers to both the tour of 28 events and an annual ranking system based upon performances in these. The World Ranking was launched in 2009, and merged fully with its predecessor the UCI ProTour in 2011.  - The UCI Road World Cup was a season-long road bicycle racing competition comprising ten one-day events. The competition was inaugurated in 1989, and replaced the Super Prestige Pernod International. In the first three years, the competition was sponsored by Perrier. The competition determined a winning individual, and a winning team    Given the paragraphs above, decide what entity has the relation 'sport' with 'track cycling'.
