Introduction:
The history of earth mainly concerns with the development of the planet earth from the day it was formed to the present day. All branches of natural science have participated in the understanding of the main events, which took place in the earth’s past and are characterized by constant geological alteration and biological evolution.
Answer to Problem 1TYK
Correct answer:
Earth was formed
Explanation of Solution
Justification/explanation for the correct answer:
Option (d) is
Explanation for the incorrect answers:
Option (a) is that Earth was formed about
Option (b) is that Earth was formed
Option (c) is that earth was formed
Option (e) is that earth was formed about
Hence, options, (a), (b), (c), and (e) are incorrect.
Thus, it can be concluded that because Big Bang theory and Permian period gave the proof for the existence of earth and living cell.
