earth history
Our planet's timeline
Earth history is the study of geological time and the physical and biological changes our planet has undergone over billions of years—continental drift, mass extinctions, ice ages, the emergence of life.
The term appears in academic and educational contexts: an earth history course, the earth history of the Grand Canyon.
Sometimes written as one word: Earth-history.
