Question

Why is it difficult for scientists to find fossils from the Precambrian period?

A)There are no rocks left on Earth that exist from this period.
B)Life did not exist during this period.
C)The life that existed had soft bodies, which rarely left behind fossils.
D)Scientists cannot date rocks before the Precambrian period.

Answer 1

Answer: (C) The life that existed had soft bodies, which rarely left behind fossils.

Explanation: Fossils are formed when the organisms are pressed between layers of rocks. If the organisms are too soft, they will leave only a faint imprint on rocks. The organisms present in the Precambrian period were soft. So, fossils of these organisms are difficult to find.

Step-by-step explanation:

Fossils are formed when the organisms are pressed between layers of rocks. If the organisms are too soft, they will leave only a faint imprint in rocks. The organisms present in the Precambrian period were soft. So fossils of these organisms are difficult to find.
