Context: 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. , Subject: petrology, Relation: instance_of, Options: (A) affix (B) atmosphere (C) biology (D) branch (E) case (F) century (G) combination (H) formation (I) geography (J) geology (K) harbor (L) inner planets (M) language (N) millennium (O) physics (P) planet (Q) plate (R) science (S) suffix (T) system (U) term (V) terra (W) terrestrial planet (X) understanding (Y) verb
