ARadioactive forceBTidal forceCVegetation forceDGlacial force

Question 4ExpertLevel 28

According to Wegener movement toward the equator was related to which force?

APole-fleeing forceBAlluvial forceCNon-Coriolis forceDAtmospheric pressure force

Question 5ExpertLevel 28

What was the greatest scientific weakness of Wegener's theory?

AIt ignored continental shapesBIt gave no fossil evidenceCIts proposed forces were insufficient for such huge displacementDIt did not propose Pangaea

Question 6ExpertLevel 28

AAfrica and BrazilBLaurasia and GondwanalandCAustralia and AntarcticaDIndia and Madagascar

Question 7ExpertLevel 28

In Wegener's theory around what time is the breakup of Pangaea generally considered to have begun?

AAbout 200 million years agoBAbout 2000 years agoCAbout 50 years agoDAbout one billion years later

Question 8ExpertLevel 28

Why is the similarity of facing coasts of Africa and South America not considered decisive by itself?

ABecause coastlines change by erosion and depositionBBecause both continents are roundCBecause ocean water is blueDBecause maps are never useful

Question 9ExpertLevel 28

The comparison of gold deposits on the Ghana coast and goldfields in Brazil provides what type of evidence?

AClimatic evidenceBPlacer deposit and source area evidenceCVolcanic eruption evidenceDOcean salinity evidence

Question 10ExpertLevel 28

In Continental Drift Theory India's northward movement is broadly linked with which later result?

AComplete disappearance of AravalliBBackground of Himalayan formationCSahara becoming a seaDAntarctica remaining fixed at the equator

Question 11ExpertLevel 28

In Wegener's theory continents were considered to move through which medium which later drew criticism?

AThrough rigid oceanic crustBOnly within the atmosphereCOnly with riversDIn complete empty space

Question 12ExpertLevel 28

Which is the best example of palaeoclimatic evidence in Continental Drift Theory?

AGlacial tillite in Gondwana regionsBHeight of sea wavesCDistance between modern citiesDColour of river deltas

Question 13ExpertLevel 28

If a continent is tropical today but contains ancient glacial rocks what may it indicate?

AIts climate and position may have been different in the pastBRocks were never formed thereCAll glacial rocks are fakeDSolar energy has ended

Question 14ExpertLevel 28

What was the main reason Wegener's theory did not gain immediate full acceptance?

AHe did not provide a convincing physical mechanism for continental movementBHe never saw any mapCHe completely rejected fossilsDHe considered Earth flat

Question 15ExpertLevel 28

What is the most important difference between Continental Drift Theory and Plate Tectonics?

AContinental drift focused on continents while plate tectonics explains movement of lithospheric platesBThere is no difference between themCPlate tectonics treats fossils as wrongDContinental drift was only a weather theory

Question 16ExpertLevel 28

Arthur Holmes's idea of convection currents addressed which weakness of Wegener's theory?

ALack of evidenceBLack of driving mechanismCLack of mapsDLack of fossil names

Question 17ExpertLevel 28

In Wegener's theory in what sequence is the division of Pangaea understood?

AFirst Laurasia and Gondwanaland then further smaller continentsBFirst modern countries then oceansCFirst cities then mountainsDFirst rivers then planets

Question 18ExpertLevel 28

Which conclusion is most logical from Wegener's fossil evidence?

AThe same species always spreads by swimming across every oceanBBiological distribution was continuous before continents separatedCFossils form only in desertsDClimate never changed on Earth

Question 19ExpertLevel 28

What does continuity of rock sequences mean in support of continental drift?

ARock belts on separated continents may once have been parts of one geological beltBAll rocks formed on the same dayCRocks are not found on continentsDOceans do not produce rocks

Question 20ExpertLevel 28

Palaeomagnetic evidence was not a major original proof of Wegener yet why did it later become important?

AIt strongly supported seafloor spreading and plate movementBIt destroyed fossilsCIt made all rock ages zeroDIt stopped Earth's rotation
