Question 1HardLevel 28

What is the most appropriate reason for not treating coastline fit alone as decisive evidence in Wegener's evidences?

ACoastlines may change by erosion and depositionBCoastlines do not exist on continentsCCoastlines form only by glaciersDCoastlines are made of fossils

Question 2HardLevel 28

In Continental Drift Theory what problem does the concept of Pangaea solve?

ACause of modern country bordersBExplanation of similar rocks fossils and coastlines on separate continentsCCause of daily temperature changeDCause of ocean water salinity

Question 3HardLevel 28

Which is the correct analysis of the position of the Tethys Sea?

AIt was another name of PanthalassaBIt surrounded Pangaea from all sidesCIt was a separating sea between Laurasia and GondwanalandDIt was only the old name of the Atlantic Ocean

Question 4HardLevel 28

How is Wegener's biggest scientific weakness understood?

AHe did not use the term PangaeaBHe gave no fossil exampleCHe did not discuss coastline fitDHe did not give an adequate mechanical mechanism for continental movement

Question 5HardLevel 28

Mesosaurus fossil evidence is considered serious because it challenges what?

AThe assumption that distant continents always remained separateBThe assumption that fossils never formCThe assumption that oceans contain waterDThe assumption that glaciers occur in cold regions

Question 6HardLevel 28

What type of clue does the distribution of Glossopteris fossils give for Gondwanaland?

ASimilarity of present citiesBOld biological and geographical relation of southern landmassesCEqual height of sea wavesDModern political boundaries

Question 7HardLevel 28

What conclusion becomes stronger by studying tillite deposits and glacial striations together?

AContinents have equal population todayBOceans never formedCLandmasses were earlier joined and in different climatic positionsDAll mountains were made by humans

Question 8HardLevel 28

How is the relation between placer gold in Ghana and source areas in Brazil read in support of Wegener?

AIt shows only present trade routesBIt shows gold forms in seawaterCIt shows only Africa's climateDIt shows possibility of old mineral source and land connection

Question 9HardLevel 28

Why was Wegener's explanation of pole fleeing force considered insufficient?

AIt was not considered strong enough to move continental massesBIt was completely unrelated to Earth's rotationCIt was based only on plant fossilsDIt was another name for the Tethys Sea

Question 10HardLevel 28

What was the main problem in Wegener's tidal force explanation?

AIt was not related to Sun and MoonBIt explained only present weatherCSuch force was not considered sufficient to move continentsDIt disproved fossils

Question 11HardLevel 28

On what basis was the idea of continents drifting over the ocean floor criticised?

AOcean floor was considered a resistant solid mediumBOceans were made entirely of gasCContinents had no rocksDFossils did not exist

Question 12HardLevel 28

Which basic weakness of Wegener did plate tectonics later explain better?

ALack of the name PangaeaBLack of mechanism for continental movementCAbsence of coastline evidenceDAbsence of fossil evidence

Question 13HardLevel 28

How does the idea of sea floor spreading indirectly support Wegener's theory?

AIt shows mobility of the ocean floorBIt calls Pangaea an oceanCIt rejects fossilsDIt calls continents completely fixed

Question 14HardLevel 28

What caution is needed when reading coal and glacial evidence in Antarctica together?

AThey should be treated as signs of old climate and position not present weatherBBoth should be treated as proof of modern industryCBoth should be treated as proof of political boundaryDBoth should be treated as proof of ocean salinity

Question 15HardLevel 28

What is the most appropriate meaning of linking the Indian subcontinent with Gondwanaland?

AIndia was the water part of PanthalassaBIndia was a fixed part of modern EuropeCIndia was part of the ancient southern supercontinent and later moved northwardDIndia was always west of the Atlantic

Question 16HardLevel 28

Which statement is most appropriate about the Tethys Sea and the Himalaya?

ATethys is the modern name of PanthalassaBTethys sediments and later collision are linked with the context of Himalayan formationCTethys is only the name of the South PoleDTethys is a plant fossil

Question 17HardLevel 28

Instead of memorising Laurasia and Gondwanaland only as names how should they be understood?

AAs two modern citiesBAs northern and southern parts of PangaeaCAs two riversDAs two fossils

Question 18HardLevel 28

If both similar fossils and similar rock structures are found on separate continents why does the conclusion become stronger?

ABecause both biological and geological independent clues are obtainedBBecause both show present weatherCBecause both create political bordersDBecause both measure ocean depth

Question 19HardLevel 28

When jigsaw fit of Africa and South America is linked with rock evidence what conclusion becomes better?

ANot only coastal shape but geological connection was also possibleBBoth continents are one country todayCWeather is same on both continentsDBoth continents have no rivers

Question 20HardLevel 28

Why is Wegener's theory considered historically important instead of being completely rejected?

AIt started scientific debate on mobility of continentsBIt proved Earth fixedCIt denied the existence of oceansDIt called all fossils false
