Which of the following lists the periods of the Paleozoic from youngest to oldest?

Cambrian; Ordovician; Silurian; Devonian; Carboniferous; Permian
Permian; Carboniferous; Devonian; Silurian; Ordovician; Cambrian
Carboniferous; Devonian; Ordovician; Silurian; Cambrian
Devonian; Silurian; Cambrian; Ordovician; Carboniferous; Permian

The correct answer is: Permian; Carboniferous; Devonian; Silurian; Ordovician; Cambrian

The correct choice lists the periods of the Paleozoic Era in reverse chronological order, from the youngest to the oldest, which is essential for understanding the geological time scale. The Paleozoic Era is divided into six major periods: the Cambrian, Ordovician, Silurian, Devonian, Carboniferous, and Permian. By starting with the Permian, the answer highlights the most recent period before moving backward to the older periods. This is helpful for geologists and students because understanding the sequence of these periods is crucial when considering the evolution of life, major geological events, and the overall history of the Earth during the Paleozoic. The other options do not follow the correct sequence when listed from youngest to oldest, mixing periods in ways that do not accurately reflect their chronological order. This distinction is important for effectively studying paleontology, stratigraphy, and Earth's historical geology.
