Kelli drew a diagram to compare the cast and imprint fossils.
vichka [17]

Answer:

When Kelly drew the diagram, the area marked Y -which includes cast and print- involves mold filling minerals and sediment (option D).

Explanation:

A fossil is the evidence found of an organism that lived many years ago, and consists of organic remains - such as bones - or impressions that remained in the soil.

The fossil record of a living being occurs when it dies and its remains, which are buried, when decomposing leave an impression. This impression - as a mold - is subsequently occupied by minerals and sediment that describe the approximate form of the organism.

In the Kelly diagram, the <u>area labeled Y shows not only the impression of the organism that was found, but also the minerals and sediments that were responsible for filling said mold</u>.

Although earthquakes often occur before a volcanic eruption, they are not the cause. The earthquakes are the result of magma (molten rock) moving underground leading up to an eruption.
