Four students are working together to explain the process of fossilization. Their teacher asked each student to explain why most organisms do not become fossils. The student responses are listed below. Which student has the best answer?
|
|
Aubrey:Most plants and animals do not become fossils. A very specific set of conditions must occur for fossilization to occur.
|
|
|
Billy:Fossils can form easily. Dead organisms buried in soil turn into fossil rocks.
|
|
|
Either A or B
|
|
|
None of the above

Explanation:
Detailed explanation-1: -The most common method of fossilization is permineralization. After a bone, wood fragment, or shell is buried in sediment, it may be exposed to mineral-rich water that moves through the sediment. This water will deposit minerals, typically silica, into empty spaces, producing a fossil.
Detailed explanation-2: -Fossils form in five ways: preservation of original remains, permineralization, molds and casts, replacement, and compression. Rock formations with exceptional fossils are called very important for scientists to study. They allow us to see information about organisms that we may not otherwise ever know.
