Explain Landscape Changes Over Time Practice Test

In Frost Creek Canyon, the oldest layer has fossil palm leaves and warm-climate insects in shale. Above it, younger layers contain pine needles and deer fossils in siltstone. The layers are stacked with older below younger. What changes occurred in this landscape? Use evidence from rocks and fossils.

At Blue Ridge Cliffs, rock layers are stacked with limestone at the bottom and sandstone on top. The limestone layer has many shell and coral fossils, and the sandstone layer has very few fossils. The oldest layers are at the bottom, and the youngest are at the top. Using the rock and fossil evidence, explain how this landscape changed over time.
