Position of land masses of early pennsylvania can be determined through fossil records because we know that most plants presently live on land. from this information, we can infer? a) plants are preserved as fossils b) animals are preserved as fossils c) fossils cannot be used to determine the history land position d) that rocks that contain plant fossils were also formed on land

a. plants are preserved as fossils

Explanation:

Through the passing of time, the dead bodies like plants or animals rest in soil, and the cover by different particles, with the time they can be compressed and form a soil layer. If the environment condition changes they get caught in one soil layer. If this process is repeated constantly,  so a new soil layer will be formed. So passing the time, different soil layers will have different animals or plants.  With the help of isotopes, the scientist can determine the years of each layer.

The correct answer is d

Explanation:

I know this because some plant fossils can be found underwater. Also I had to answer this question.
