Which era includes the Triassic, Jurassic, and Cretaceous periods?

• A. Mesozoic Era
• B. Precambrian Era
• C. Paleozoic Era
• D. Cenozoic Era

Answer: (A)

The main idea is identifying which era contains the three periods Triassic, Jurassic, and Cretaceous. These periods are all part of the Mesozoic Era, the middle slice of Earth's geologic history. The Mesozoic sits between the older Paleozoic and the younger Cenozoic and is well known for the age of dinosaurs. The Precambrian represents a time long before complex life and does not include these periods. The Paleozoic comes earlier and ends before the Mesozoic begins, while the Cenozoic follows after the Mesozoic. So, the era that includes Triassic, Jurassic, and Cretaceous is the Mesozoic.
