Question

Which one of the following represents the correct chronological order of geological periods (from oldest to most recent)?

• A. Devonian $\to$ Jurassic $\to$ Cambrian $\to$ Neogene
• B. Devonian $\to$ Cambrian $\to$ Neogene $\to$ Jurassic
• C. Cambrian $\to$ Devonian $\to$ Jurassic $\to$ Neogene
• D. Cambrian $\to$ Neogene $\to$ Devonian $\to$ Jurassic

Hint:

Geological periods are divided by major changes in Earth's biodiversity, with earlier periods characterized by simpler life forms and later periods by more complex organisms.

Answer 1

The Correct Option is C

The correct chronological order of geological periods, from oldest to most recent, is:
[4pt] - Cambrian: This period is one of the oldest, occurring around 541 million years ago. It marks the start of the Paleozoic era and is known for the Cambrian explosion, where many major groups of animals first appeared.
[4pt] - Devonian: Following the Cambrian, the Devonian period (419–359 million years ago) saw the evolution of fish, amphibians, and the first forests.
[4pt] - Jurassic: The Jurassic period (201–145 million years ago) follows the Devonian and is known for the dominance of dinosaurs and the first birds.
[4pt] - Neogene: The most recent period listed, the Neogene (23–2.6 million years ago), saw the development of mammals and modern plant life.
[6pt] Thus, the correct order is (C): Cambrian $\to$ Devonian $\to$ Jurassic $\to$ Neogene.
