Fossils provide information about the layers of rock in which they are found. For example, the fish fossil indicates that the sediments in the surrounding rock were deposited in or near a body of water.
What information does the fish fossil provide about the age of the rock layer surrounding it?
The rock is younger than the fossil.
The rock is older than the fossil.
The rock and fossil are the same age.
The age of the rock is unrelated to the age of the fossil.
Fossils are the preserved remains of organisms that lived long ago. According to the law of superposition, the rock layers that contain fossils should be far below Earth’s surface. Which answer best explains why fossils are sometimes found at or near the surface?
Fossils are less dense than rock, so they rise to the surface.
Fossils are moved to the surface by other organisms.
Sedimentary rock layers are relatively soft, and new fossils sink through upper layers into older, deeper layers.
Some rock layers with fossils have been exposed because of different processes, such as faulting, folding, and weathering.
Many features of rocks offer clues to their ages. Which feature does NOT provide information about the age of a rock?
the position of the rock relative to other rock layers.
the size of the crystals that make up the rock
the radioactive elements within the rock
the fossils found within the rock
Scientists find a fossil of a fish on top of a mountain. What kind of evidence does the fossil provide scientists about the way this area might have changed over time?

It shows that oceans can change quickly and become land.
It shows that the animals found on the mountain today evolved from fish.
It shows that the mountain may have once been under water and raised up by natural processes.
The picture below shows a river flowing through a canyon.
What can you infer about how the canyon looked a thousand years ago?
The canyon was just as deep but had no water.
The canyon was not as deep as it is today.
The canyon was much deeper than it is today.
The canyon looked exactly like it does today.
