Greenhouse gas. A greenhouse gas (abbrev. GHG) is a gas in an atmosphere that absorbs and emits radiation within the thermal infrared range. This process is the fundamental cause of the greenhouse effect. The primary greenhouse gases in Earth's atmosphere are water vapor, carbon dioxide, methane, nitrous oxide, and ozone.
A musician is a person who plays a musical instrument like a guitar or a piano or a person that sings. A musician is also someone who writes music, even if they write it for other people to play. People who write music are called composers. Usually that part is left out if they also play or sing the music they write, but they are still composers because they wrote the music.
General CommentThis is a great song about a happy, healthy marriage between a man and a woman. The man is saying how great his wife is, how he can see his whole world inside his her eyes, and on her finger is a band of gold, her wedding band, that shines.
