Question

Which is a factor that prevents us from finding Precambrian fossils?

O A. Rocks did not form in that era.

B. There was no life in that era.

O C. Most rocks from that era are deeply buried.

O D. Most fossils have been destroyed by meteorite impacts.

Answer 1

Most rocks from that era are deeply buried.

is the correct answer.

Answer 2

The correct answer is option C. "Most rocks from that era are deeply buried".

Step-by-step explanation:

The Precambrian is the earliest era of Earth's history, predating the emergence of life during the Cambrian Period. Even tough it is the earliest era of Earth, the Precambrian era represents 88% of all geological time, which makes evident that life is relatively new in comparison to the Earth's total geological time. Most rocks from Precambrian era are deeply buried, result of diverse phenomena in the tectonic plates along history. This make most rocks inaccessible and prevents the finding of Precambrian fossils.
