Continental Drift Theory and its evidence

Q: Wegener's theory tried to answer which question?

How continents and oceans came to present positions Wegener tried to explain the origin and positions of continents and oceans. Exam tip: understand it as an explanation of distribution.

Q: What does coastline matching mean in continental drift?

Edges of two continents having matching shapes Coastline matching shows that some continents may once have been joined. Exam tip: treat it as visual evidence.

Q: Which option is the correct group of evidences for continental drift?

Coastline fossils rocks and glacial evidence Main evidences of continental drift are coastline fossils rocks and climatic signs. Exam tip: remember evidences by category.

Q: According to Wegener continents were considered to drift over which surface?

Over ocean floor Wegener assumed continents drifted over the ocean floor. Exam tip: this idea was later considered weak.

Q: Coastal similarity on both sides of the Atlantic Ocean supports which theory?

Continental Drift Theory The coastlines of Africa and South America match on both sides of the Atlantic. Exam tip: remember this example.

Q: What was the name of the ocean surrounding Pangaea?

Panthalassa Panthalassa was the huge ocean around Pangaea. Exam tip: remember the pair Pangaea and Panthalassa.

Q: Which of the following is related to Wegener?

Continental Drift Wegener was the proposer of Continental Drift Theory. Exam tip: remember the pair of name and theory.

Q: For what purpose are evidences studied in continental drift?

To understand old connection of continents Evidences show that continents may have been connected earlier. Exam tip: connect every evidence with old connection.

Q: According to Continental Drift Theory what are oceans and continents?

Geomorphic features with positions changed over time The theory explains changing positions of continents and oceans. Exam tip: link change with geological time.

Q: In which evidence are remains of similar organisms found on different continents?

Fossil evidence Remains of similar organisms are called fossil evidence. Exam tip: use Mesosaurus and Glossopteris as examples.

In Class 11 Geography, this topic explains the Continental Drift Theory within the chapter “Distribution of Oceans and Continents.” Students learn Alfred Wegener’s idea that the continents were once joined as Pangaea and gradually moved apart. They examine evidence such as the matching shapes of coastlines, similar fossils, continuous rock formations, mountain belts, and past glacial deposits found on continents now far apart. The topic also introduces the theory’s limitations and its importance in the later development of plate tectonics.
