FAQ
Frequently Asked Questions
For the environmental/construction material, it is standardly written as two words: 'tar ball'. The computing archive file is written as one word: 'tarball'.
Yes, they can be. They contain toxic chemicals from crude oil, can harm wildlife that ingests them, and are a skin irritant for humans. They also indicate significant marine pollution.
An oil slick is a thin, continuous layer of oil floating on the water's surface. A tar ball is a discrete, semi-solid lump that forms as the slick breaks up and weathers, often washing ashore.
In technical environmental contexts, the process is sometimes described using 'tar-ball' as a phrasal verb (e.g., 'the oil tar-balls'). However, it is not a standard everyday verb and is considered jargon.
