The subdivision of the geologic time scale that represents the longest time span is called an epoch.

What is meant by epoch ?

A rock series is deposited over an epoch, or period of geological time. When used in a formal sense, the word is capitalized and refers to a subdivision of a geological epoch (e.g., Pleistocene Epoch).

More distinctions can be formed by adding relative time phrases like early, medium, and late. The term "epoch" is frequently only used in reference to the Paleogene, Neogene, and Quaternary period divisions.

An epoch is a period of time distinguished by specific characteristics; for instance, you could designate a number of peaceful decades as an epoch in the history of a nation.

In geologic time, an epoch is a division of a period, and an age is a division of an epoch.

Epoch can also refer to a particular and important historical period or a specific event that characterizes one. For instance, ballet has experienced epochs throughout its history.

Therefore, the correct answer is option a. epoch.

It is located in northern Argentina. D. It borders the Pacific Ocean. Please select the best answer from the choices provided A B C D

Explanation:

Atacama Desert is located in Chile, South America and not northern Argentina. Thus, statement C is false about Atacama.

What is known about Atacama?

The Atacama Desert is a desert plateau in South America that stretches for 1,600 kilometres along the Pacific coast, west of the Andes Mountains. The Atacama Desert is the world's driest nonpolar desert and the second driest overall, trailing only some very specific spots within the McMurdo Dry Valleys, as well as the only hot true desert that receives less precipitation than the polar deserts and the world's largest fog desert.

In 2010, the world's attention was drawn to the Atacama Desert. Famous for the 'Copiapo mining accident,' in which 33 miners were buried for a record 69 days in a 120-year-old copper-gold mine. On October 13, 2010, all 33 miners were safely rescued.

Therefore, Atacama Desert is not located in northern Argentina but in Chile.
