Choose the correct answer from the options given below:
Answer & explanation
Correct answer: option 4
The correct answer is Option (4) → (C), (D), (A), (B)
The geological time scale, from the oldest of these periods to the latest, runs Carboniferous → Permian → Triassic → Jurassic → Cretaceous → Tertiary → Quaternary. The question asks for the order from latest to oldest, so the list is read from the top of the book’s chart downwards.
(C) Tertiary — first (latest). It belongs to the Cenozoic era, the era of flowering plants and mammals.
(D) Jurassic — second. It is the middle period of the Mesozoic era, the age of dinosaurs.
(A) Triassic — third. It is the first period of the Mesozoic, just after the Permian.
(B) Carboniferous — fourth (oldest). It lies in the Paleozoic era, when large fern-like forests grew.
