Sedimentary Rock Environments

The diagram shows some fossils embedded in layers of underground rock. Based on the diagram, which statement best describes how the area has changed over time?

• The area was always land, but it was home to different life-forms.

• The area was underwater, and then it became land.

• The area started as land, then was underwater, then finally became land again.

• The area started under water, then was land, and finally was underwater again.

A scientist discovers fossils of thousands of fish in the desert. Most likely, this is evidence that

• large dinosaurs once lived in the area.

• a trash dump was located at this spot.

• prehistoric fish could live without water.

• an ocean may once have covered the area.

• The Antarctic will be covered in ice for millions of years.

• The Antarctic has daylight only six months of the year.

• These plants have adapted to live in the Antarctic.

• The climate in the Antarctic was very different in the past.
