Which of the following evidence supports the theory of continental dr...
Evidence supporting the theory of continental drift:
1. Jigsaw fit of shorelines of Africa and South America
- The shorelines of Africa and South America fit together like puzzle pieces, suggesting that they were once joined together.
- This is evidence of plate tectonics, which explains how the Earth's crust is made up of plates that move and shift over time.
2. Occurrence of gold deposits in Ghana coast but the absence of any source rocks there
- The presence of gold deposits in Ghana's coast suggests that they were once connected to a region that had gold source rocks.
- This supports the theory of continental drift, as the movement of continents could have caused the separation of the gold source rocks from the Ghana coast.
3. All the east South American and West African coasts are good natural harbours
- The similarity in the coastline features of both regions suggests that they were once connected.
- This is evidence of plate tectonics, as the movement of the continents could have caused the separation of the two regions while maintaining their similar coastline features.
Therefore, the correct answer is option 'A', as evidence 1 and 2 support the theory of continental drift.
