At what stage and in what eon did the earth develop seasons?

a. early phanerozoic eon
b. late precambrian eon
c. late phanerozoic eon
d. early precambrian eon

C. Late Precambrian era

Explanation:

Eon refers to two or more geological eras forms an eon. Eon is mainly divided into four eon namely Hadean, Archean, Proterozoic and Phanerozoic. Phanerozoic includes Palaeozoic, Mesozoic and Cenozoic era. Cambrian falls under the Palaeozoic era which was the major turning point the evolution period of geological time scale. The sudden increase in many diversity of animal phyla was evolved during this period. Also, the first land plant was appeared in this period which gave a promising fact that plants will grow on the apt seasonal conditions.

Option B, Late Precambrian eon

Explanation:

The history of geology of Earth has started somewhere around 4.6 billions ago.

Basically , it can be divided into two periods

a) the Precambrian supereon and

b) the Phanerozoic eon.

The Precambrian supereon   has 90 percent of geologic time . It has 3 eons and begins some 4.6 billion years ago and extends up to the start of Cambrian Period.

a) Hadean Eon - it is the era before the formation of rocks.

b) Archean Eon - During this eon, Archean rocks metamorphized  deep-water sediments

c) Proterozoic Eon - Rocks found in this eon revealed massive, rapid continental accretion  supercontinent cycles, and  orogenic activity

Hence, option B is correct

hi~~

i would say that hybridization occurs frequently in nature, because there are many types of hybrids that have occurred naturally, such as the mule (male donkey + female horse)

a physical change is being made.
