With reference to Wegener's theory of continental drift, which of the following statements is correct? I. This theory dates back to the pre-Carboniferous period. II. The main purpose of the theory was to explain the major climatic changes in the geological history of the Earth. Correct Answer  II only

The correct answer is II only.

Key Points

  • Continent drift was a revolutionary theory explaining that continents shift position on Earth's surface.
  • The theory was proposed by geophysicist and meteorologist Alfred Wegener in 1912.
  • Wegener's continental drift theory introduced the idea of moving continents to geoscience.
  • He proposed that the Earth must have once been a single supercontinent before breaking up to form several different continents.
  • The main purpose of the theory was to explain the major climatic changes in the geological history of the Earth.

​ Thus, we can say that the main purpose of Wegener's Continental Drift was to explain the climatic changes in the geological history of the Earth.

 Confusion Points

  • The theory does not date back to the pre-Carboniferous period but was proposed in 1912.
