C. Trees grew first on the land. Then the sea rose and killed the trees. Lastly, lava from a volcano covered the land.

D. An ocean first covered the land. Then lava from a volcano covered the area. Lastly, trees grew on the land.

shale

Sedimentary layer

Basalt (lava)

Use the following story to answer the question:

Mineral FossilizationWhen an organism died and becomes buried in sediment, mineral fossilization may occur. Soft parts of the organism decay quickly, while hard parts, such as bones, take more time.
