The word “epoch” is pronounced with a hard “c” sound, as in the word “cat.” The “e” in the first syllable is pronounced like the “a” in “apple,” and the “o” in the second syllable is pronounced like the “o” in “go.” Therefore, the word “epoch” is pronounced as “EP-uh-k.”
Epochs are important units of geologic time. They are used to divide the Earth’s history into distinct periods, each of which is characterized by a unique set of geologic events. Epochs are typically millions of years long, and they are often used to track the evolution of life on Earth.
