In a sequence of rock layers, how can you tell which layer is older than the other?
The older rock layers can be found below the younger layers.
The younger rock layers can be found below the older layers.
The older rock layers are closest to the surface.
The younger rock layers are deeper down.
What information does radiometric dating give scientists about a rock?
How much the rock costs
How long it has been since the rock formed
How much rock is layered on top of it
How many fossils are stored in the rock
How can finding marine (ocean) fossils at the top of mountains be used as evidence that evolution has occurred?
Shows that this environment has stayed the same over time
Shows that the mountain will become an ocean
Shows that fish were able to swim to the top of the mountain
Shows that an ocean once covered the mountain
How could scientists use the fossil record to show how plants have changed over time?
Scientists can compare fossils of plants from the same rock layer to see how they have changed.
Scientists cannot use the fossil record, because plants cannot become fossils.
Scientists can compare fossils of many plants from many different time periods to see how they have changed.
Scientists can examine plant fossils to determine what kind of animals ate them.
When trying to determine whether or not organisms share a common ancestor, what evidence could scientists examine?
Metamorphic Rocks
Homologous Structures
Plate Tectonics
Natural Selection
How can fossils be used to show how organisms have changed over time?
Can compare fossils of various ages to observe how an organism has changed over time
Cannot use fossils to show how an organism has changed over time
Can compare fossils from in the same rock layer to show how an organism has changed over time
Can identify the type of fossil to determine how an organism has changed over time
What is the purpose of an index fossil?
determines how fossils form in a rock layer
determines how species evolve
determines the age of a rock layer
determines the amount of fossils in a rock layer
What are 2 environments that you could find fish bones in?
Forests, Rainforests
Oceans, Lakes
Oceans, Forests
Deserts, Forests
How does an intrusion impact the relative age of the rock layers it cuts through?
An intrusion is the same age as the layer it is cutting through.
An intrusion is older than the layer it is cutting through.
An intrusion is younger than the layer it is cutting through.
An intrusion does not cut through rock layers.
Which of the following was the key species in the Cenozoic Era?
Mammals
Dinosaurs
Cone bearing plants
Reptiles
How does taxonomy classify organisms?
Classifies organisms based on similarities or differences in anatomical (body) structures
Classifies organisms based on their names
Classifies species based on how long they've existed
Classifies species randomly
What information can ice cores give scientists?
Index fossil data
Law of Superposition data
Unconformity data
Climate or Atmospheric data
Which of the following gives evidence for the theory of plate tectonics?
Ice cores, show how the atmosphere has changed over time
Earthquakes, shows that the plates are constantly moving
Homologous structures, show similarities between organisms
Sedimentary rocks, show that fossils can be stored in them
How can homologous structures indicate a common ancestor between 2 species?
2 species having no similarities shows that they may have once been related
2 species having structures that no longer serve a purpose shows that they may have once been related
2 species having similar structures shows that they may have once been related
2 species with variation in their DNA shows that they may have once been related
What often causes species to go extinct?
Erosion of rock layers
Small gene mutations
Plate Tectonics
Environmental Changes
