-ology, -logy, -ologist, -logist
(Greek: a suffix meaning: to talk, to speak; a branch of knowledge; any science or academic field that ends in -ology which is a variant of -logy; a person who speaks in a certain manner; someone who deals with certain topics or subjects)
The word -ology is a back-formation from the names of certain disciplines. The -logy element basically means "the study of ____". Such words are formed from Greek or Latin roots with the terminal -logy derived from the Greek suffix -λογια (-logia), speaking, from λεγειν (legein), "to speak".
The suffix -ology is considered to be misleading sometimes as when the "o" is actually part of the word stem that receives the -logy ending; such as, bio + logy.
Through the years -ology and -logy have come to mean, "study of" or "science of" and either of these suffixes often utilize the form of -ologist, "one who (whatever the preceding element refers to)".
The examples shown in this unit represent just a small fraction of the many words that exist in various dictionaries.
2. The study of light pollution at night as it directly impacts biological existence which is usually specifically affected by darkness.
Plants and animals are programmed to function in a certain pattern of daylight and darkness. Alter those patterns and unhealthy things often happen.
It applies equally to organisms that are active at night and those, including humans, whose bodies require regular periods with the lights out.
Some people believe that as with all types of pollution, light pollution contaminates the natural environment and produces side effects that should be mitigated or avoided, if possible, to create a balance between necessary urban light levels and a healthy environment.
Sedimentology is also influenced by movements caused by gravity or motions caused by erosion; such as, when sediment rolls or goes downhill in a landslide or when it is carried away by water, wind, or moving ice in glaciers.
