Continental Drift Theory and its evidence

Question 1ExpertLevel 29

Why are continental shelf edges considered a better basis for matching than shorelines?

AThey show political boundariesBThey show the real continental edge beneath the seaCThey show only river mouthsDThey measure atmospheric pressure

Question 2ExpertLevel 29

According to Wegener the basic continental material was associated with which term?

ASialBSimaCNifeDMagma

Question 3ExpertLevel 29

In Wegener's view the oceanic base material was related to which term?

ASialBSimaCLaurasiaDPangaea

Question 4ExpertLevel 29

Why did continents ploughing through sima become a subject of criticism?

ABecause it was considered mechanically unrealisticBBecause fossils are not found from itCBecause it stops rainfallDBecause it makes Earth flat

Question 5ExpertLevel 29

Pole-fleeing force was mainly linked with which cause?

ASolar eclipseBRiver erosionCEarth's rotation and equatorial bulgeDOcean salinity

Question 6ExpertLevel 29

Why was tidal force considered an insufficient cause of continental drift?

ABecause it never affects rocksBBecause it only forms glaciersCBecause it carries fossils into the seaDBecause the required force was far greater than the real tidal force

Question 7ExpertLevel 29

What is the correct relation between geographical fit and geological fit in Wegener's evidence?

AGeographical fit gives a clue and geological fit strengthens itBGeographical fit is always wrongCGeological fit only tells weatherDNeither has any relation with the theory

Question 8ExpertLevel 29

What is the importance of Mesosaurus being associated with freshwater in the evidence?

AIt shows it lived in desertsBIt shows it could not cross a vast oceanCIt shows it was a modern mammalDIt shows it formed mountains

Question 9ExpertLevel 29

What is the main importance of Glossopteris fossils in Gondwana evidence?

AIt shows a common plant distribution on separated landmassesBIt is evidence of a modern marine fishCIt proves only tidal forceDIt measures ocean salinity

Question 10ExpertLevel 29

Study of the direction of ancient glacial striations helps understand what?

APresent length of riversBDirection of ancient ice movementCColour of seawaterDModern population density

Question 11ExpertLevel 29

Tillite is considered which type of evidence in support of continental drift?

AEconomic evidenceBPolitical evidenceCGlacial and palaeoclimatic evidenceDAstronomical evidence

Question 12ExpertLevel 29

What does evidence of Carboniferous glaciation in Gondwana landmasses indicate?

AThose landmasses may once have been together in southern high latitudesBAll of them are fixed at the equator todayCThey were only volcanic islandsDThey were never rocky

Question 13ExpertLevel 29

How should the role of the Tethys Sea in Wegener's theory be understood most correctly?

AIt was the ocean surrounding PangaeaBIt was an intermediate sea between Laurasia and GondwanalandCIt was a desert of South AmericaDIt was a polar ice sheet

Question 14ExpertLevel 29

What was the basic difference between Panthalassa and Tethys?

APanthalassa was landmass and Tethys was mountainBBoth were modern riversCPanthalassa was the outer vast ocean and Tethys was an inner intermediate seaDBoth were fossil plants

Question 15ExpertLevel 29

The division into Laurasia and Gondwanaland was part of which larger idea?

AThe idea of Pangaea's breakupBThe idea of monsoon originCThe idea of river valley civilizationDThe idea of earthquake intensity

Question 16ExpertLevel 29

Similarity of rock structure between Africa and South America strengthens which conclusion?

AThe two landmasses were once connectedBBoth are the same country todayCClimate never changed in bothDBoth are oceanic islands

Question 17ExpertLevel 29

Why are placer deposit examples included among Wegener's evidences?

AThey show relation between old source area and present deposit areaBThey show only plant growthCThey measure ocean depthDThey tell distance of planets

Question 18ExpertLevel 29

What is the importance of same-aged rocks for Wegener's theory?

AThey show old geological continuity on separated continentsBThey tell only weather temperatureCThey tell the number of marine fishDThey prove satellite motion

Question 19ExpertLevel 29

If identical fossils and similar rock sequences are both found on two continents why does the evidence become stronger?

ABecause two independent evidences point to the same former connectionBBecause fossils always destroy rocksCBecause rock sequence stops weatherDBecause oceans create fossils

Question 20ExpertLevel 29

In Wegener's theory the widening of the Atlantic Ocean was linked with which idea?

ADue to Africa and South America moving apartBDue to melting of AntarcticaCDue to direct river erosionDDue to permanent wind pressure
