Evolution and interactions among galaxiesMost fully-formed galaxies reside in small groups and clusters, where they can interact with other galaxies. These interactions can have major effects on the characteristics of a galaxy. Use the labels to complete the descriptions of how interactions can cause galaxies to evolve over time. Match the words in the left column to the appropriate blanks in the sentences on the right. Make certain each sentence is complete before submitting your answer. a) a rapid and intense period of star formationb) a minor mergerc) a tidal stream of starsd) a major mergere) galactic cannibalism
