Multiple choice

What is the process by which an organism's remains are replaced by minerals called?

  1. Petrification.

  2. Mummification.

  3. Carbonization.

  4. Freezing.
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Petrification is the process by which an organism's remains are replaced by minerals. This process occurs when minerals dissolved in water seep into the organism's remains and replace the organic matter. Petrified fossils are often found in sedimentary rocks.
