You are an archeologist who just found a fossil of a shell. As you keep digging, you discover a prehistoric fish. What can you conclude about the age of the shell in relation to the fish fossil by comparing which layer you found them in.
The Shell is older than the fish fossil because it was not as deep as fish fossil
The fish fossil is older than the shell because it was in a deeper layer
They are both the same age
The Andes Mountains in South America contain dozens of fossils of marine animals. How might you have described the landscape of the Andes mountain area long ago? What type of environment was it long ago.
Marine animals lived on land.
The Andes Mountains once were under water.
The Andes Mountains were formed by an earthquake.
The fossils of clams, which live at the seashore, were found in a rock layer directly below a rock layer that contained tree fossils. This evidence can be used to support the idea that -
fossils form more quickly at the seashore than other places.
clams and trees are always found in the same area.
the area where the fossils were found changed over time.
the layer containing the trees is older than the clam layer.
Several layers of rock are illustrated in their unchanged positions. Which of the following conclusions is supported by the data in this illustration?
Rock layer W is the oldest of all the rock layers shown.
Rock layer X was formed just before rock layer Y
Rock layer Y is twice as old as rock layer W.
Rock layer Z is the oldest of all the rock layers shown.
A diagram of rock layers is provided. The diagram shows a place where some of the rock layers were broken and shifted by an earthquake. The evidence from the patterns in this rock suggests that the earthquake happened -
just after all four rock layers shown, W, X Y and Z, had already formed.
long before any of the four rock layers shown, W, X Y and Z, had yet formed.
after rock layers Y and Z formed, but before rock layers W and X formed.
after rock layers W and X formed, but before rock layers Y and Z formed.
A diagram showing the types of fossils which were discovered in two rock layers is provided. Ferns are plants found in areas with very wet soil, while cacti do not need much water at all to survive. Based on this information, it can be concluded that the area where these rock layers formed changed in what way?
Lots of plants changing to almost no plants
Cold and icy changing to very hot
Deep ocean changing to high mountain
Very dry changing to much more damp
The tables provide information on plant and animal fossils. Based on the information, which two fossils would most likely be found in the same layer of rock?
Fish skull, FernBShark’s tooth, Marsh grass
Shark’s tooth, Marsh grass
Alligator toe bone, Seaweed
Mouse skull, Cactus
