The matching coasts of Africa and South America are seen on both sides of which ocean?
Correct answer: B
Africa and South America lie on opposite sides of the Atlantic Ocean. Exam tip: remember coastal matching across the Atlantic.
View question detailsTillite deposits are considered which evidence of Continental Drift?
Correct answer: A
Tillites are linked with old glacial deposits. Exam tip: connect tillite with glacial evidence.
View question detailsWhat does the same direction of old glacial striations on several continents show?
Correct answer: A
Glacial striations suggest some continents may have been joined earlier. Exam tip: use similar direction as evidence.
View question detailsWhich force did Wegener suggest for continental drift?
Correct answer: A
Wegener suggested pole-fleeing and tidal forces but they were considered insufficient. Exam tip: remember this as a weakness of the theory.
View question detailsWhat was the main weakness of Wegener's theory?
Correct answer: A
Wegener could not give a satisfactory cause of continental movement. Exam tip: consider lack of force as the main criticism.
View question detailsIn Continental Drift Theory what was assumed about the movement of continents?
Correct answer: A
Wegener suggested continents drifted over the ocean floor. Exam tip: this idea was later considered problematic.
View question detailsSimilarity of placer deposits belongs to which type of evidence?
Correct answer: A
Placer deposits provide evidence of mineral similarity. Exam tip: remember them as economic geological signs of continental connection.
View question detailsIndia was considered part of which old southern landmass?
Correct answer: B
India is considered part of ancient Gondwanaland. Exam tip: link India with the southern supercontinent.
View question detailsWhat does the occurrence of coal in Antarctica indicate?
Correct answer: A
Coal indicates old vegetation and a different climate. Exam tip: link it with climate change and drift.
View question detailsThe Continental Drift Theory tries to explain which type of change?
Correct answer: A
This theory explains the changing positions of continents on Earth surface. Exam tip: connect it with geological time.
View question detailsWhich example among Continental Drift evidences is related to fossils?
Correct answer: A
Mesosaurus was a small freshwater reptile whose fossils were found in both South America and Africa. Since it could not have crossed a wide ocean, these fossils support the idea that the continents were once joined. Tillite is evidence of glaciation, not fossil evidence. Exam tip: remember Mesosaurus and Glossopteris as fossil evidence for continental drift.
View question detailsWhich statement is correct in the Continental Drift Theory?
Correct answer: A
The theory is based on continents once forming one landmass. Exam tip: Pangaea names this idea.
View question detailsWhich later development gave more scientific basis to Wegener's idea?
Correct answer: A
Plate tectonics explained continental movement better. Exam tip: remember the sequence from Wegener to plate tectonics.
View question detailsWhich landmasses are mainly considered part of Laurasia?
Correct answer: A
Laurasia was the northern supercontinent including North America and Eurasia. Exam tip: call Laurasia the northern landmass.
View question detailsWhich landmass is considered part of Gondwanaland?
Correct answer: A
Antarctica is considered part of Gondwanaland. Exam tip: link southern continents with Gondwanaland.
View question detailsIn Continental Drift Theory the separation of continents is related to what?
Correct answer: A
Separation of continents is linked with the breaking of Pangaea. Exam tip: remember breakup and drift together.
View question detailsWhy is the example of Africa and South America important in Continental Drift Theory?
Correct answer: A
The Atlantic coasts of both continents suggest old connection. Exam tip: treat it as the easiest visual evidence.
View question detailsWhich of the following is not an evidence of Continental Drift?
Correct answer: D
Daily temperature fluctuation is related to weather not continental drift. Exam tip: choose long-term geological evidence.
View question detailsWegener built his idea mainly on what basis?
Correct answer: A
Wegener noted similarities in coasts rocks fossils and climatic signs. Exam tip: remember the group of evidences together.
