Question

Which is the latest era of the geological time scale?
(a). Azoic
(b). Proterozonic
(c). Cenozoic
(d). Mesozoic

Answer 1

Hint: It is the current and most recent of the three geological eras of the Phanerozoic Eon. It follows the Mesozoic and extends from 66 million years ago to this day. It is generally believed to have started on the first day of the Cretaceous–Paleogene extinction event when an asteroid hit the Earth.

Complete answer:
The Azoic era is that era without life which incorporates the origin of the world, it’s cooling down and other changes to form it suitable for all time forms. The Proterozoic period (2000 million yrs prior and traversed for 1500 million years), the time of early life, is set apart by the development of oxygenic air and the presence of the main eukaryotic cell. Mesozoic time (from 230 million years prior to 63 million yrs back) is that the time of archaic life and incorporates three periods to be specific, Cretaceous (135 million a long time), Jurassic (180 million years), and Triassic (225 million years). It is also known as the age of gymnosperms or the age of reptiles. The Cenozoic period is the time of present-day life and is otherwise called the time of well-evolved creatures and angiosperms. It started 63 million yrs back is as yet proceeding with which makes it the latest/most recent.

Additional information:
The Cenozoic is otherwise called the Age of Mammals on the grounds that the earthbound creatures that ruled the two sides of the equator were vertebrates – the Eutherians (placentals) in the northern half of the globe and the Metatherians (marsupials, now mainly restricted to Australia) within the hemisphere. The termination of the numerous gatherings permitted well-evolved creatures and fowls to extraordinarily enhance all together those huge vertebrates and winged animals ruled the world. The landmasses likewise moved into their present situations during this time.
The Earth's atmosphere had started a drying and cooling pattern, coming full circle inside the glaciations of the Pleistocene, and incompletely balanced by the Paleocene-Eocene Thermal Maximum.

So, the correct answer is ‘Cenozoic’.

Note: The basic utilization of ages during the Cenozoic assists scientists with bettering coordinates and gathering the different huge functions that happened during this nearly short time frame. Knowledge of this era is more detailed than the other era due to the relatively young, well-preserved rocks related to it.
