Answers to SELECTED Questions

Part 1: Earth’s History

2. What is an index fossil? Why are they important to the study of rock layers?

3. What is an unconformity? Why might there be an unconformity in a formation of rock layers?

a fossil from a brief period of timebut widely distributed around the earth; used to date rock layers

An unconformity is a gap (missing layer) in the Fossil record. Usually the result of weatheringor erosion of a layer of rock.

4. What is the Law of Superposition?

9. Consider the following examples, and decide if they represent relative dating or radioactive dating:

a. A fossil is 2.5 million years old _________________A trilobite fossil is older than a pelecypod fossil

_________________________The earth is at least 4.5 billion years old _________A graptolite fossil is younger than a brachiopod

_______________________

The oldest rocks lie on the bottom and theYoungest rocks are on top of any Undisturbed sequence of sedimentary rocks.

radioactive

radioactiverelative

relative

13. What is the oldest Era? ___________________What Era are we living in? ____________________

14. What is an ice core? What can they tell us?

15. What is the relationship between geological and biological evolutionary theories?

Precambrian EraCenozoic Era

An ice core is a cylinder of ice removed from a glacier. They can show us that the climate changed at certain times in Earth’s history.

They both provide evidence of change on Earth

Answers to SELECTED Questions

Part 2: Natural Selection & Biological Evolution

16. What are the 4 components of Natural

Selection?A.B.C.D.

Life is a struggleVariation (differences) among offspringOrganisms over-produce (make lots of babies)The best adapted survive and reproduce

17. Who developed the theory of Natural Selection? ______________________________

18. How does Natural Selection lead to evolution?

19. Where did life on Earth most likely begin? Circle the best answer: airvolcanoes

oceans land

Charles Darwin

Helpful traits accumulate (increase) amongsurviving members of the species

Test Practice

20. The shaded areas of this diagram represent where fossils of a land-dwelling animal were found on the continents of South America and Africa.

What does this evidence suggest?A The animals swam from one continent to the other. B The two continents were once connected by a land bridge. C The animals developed on the two continents at the same

time. D The two continents were once joined as part of a larger

continent.

21. A layer of marine fossils is discovered in a desert environment. Which hypothesis best explains the discovery?

A The area was once covered by water.B Volcanic activity once occurred in the area.C A catastrophic event once occurred in the area.D Erosion turned most of the limestone in the area

into sand.

22. Fossils of warm-weather plants were found on an island in the Arctic Ocean. What can best be concluded from this discovery?

A Spores of plants drifted by air currents to the island.B Ocean currents carried the plants to the island.C The island drifted from a tropical region to its

present location.D Seeds of plants have been carried to the island by

migratory birds.

23. Which theory best describes how an asteroid striking Earth may have caused the extinction of dinosaurs?

A Heat from the asteroid caused massive fires that reduced the food supply.

B Dense clouds formed following the collision, causing a global drop in temperature.

C Land masses were altered by the collision, reducing the space where dinosaurs could roam for food.

D Glaciers melted rapidly from heat produced by the asteroid, causing floods that destroyed dinosaurs’ habitats.

24. This diagram shows a cross section of land that has not been overturned and includes a fossil.

What can be concluded about the age of the fossil?

A It is younger than the shale. B It is older than the shale. C It is older than the sandstone. D It is younger than the sandstone.

25. Which best explains how geologic time scales can help scientists study the evolution of life on Earth?

A They describe the existence of rocks before there was life on Earth.

B They show that geological features have evolved at the same rate as organisms.

C They compare the life histories of species that have used rocks as habitats.

D They correlate the existence of life on Earth with geological events.

26. Which statement supports the theory of evolution?

A All living cells come from previous cells.B All plants and animals have DNA.C Matter cannot be created or destroyed during

chemical reactions.D Fossils provide evidence that vertebrates

share a common ancestor.

27. A scientist has a hypothesis that a large volcanic eruption caused a change in global temperature. Which information gained from ice cores is most useful in supporting the scientist’s hypothesis?

A levels of dissolved oxygen B identities of trace metals C estimates of natural radioactivityD amounts of atmospheric dust

28. The theory of global warming is based on an increase of what atmospheric gas?

A carbon dioxide B helium C hydrogen D oxygen

29. The Mid-Atlantic Ridge exists between the African and South American geologic plates. Which process most often occurs at the Mid-Atlantic Ridge?

A Destruction of underwater mountainsB creation of new continents C subduction of geologic plates D spreading of sea floor
