Alfred Wegener proposed the theory of continental drift in the early 20th century, which suggested that continents were once connected in a supercontinent called Pangaea. This theory laid the foundation for our understanding of plate tectonics and the movement of the Earth's continents.

Which scientist discovered that the continents were once one land mass?

Alfred Wegener, a German meteorologist and geophysicist, proposed the theory of continental drift in 1912. He suggested that the continents were once interconnected in a supercontinent he called Pangaea. This idea laid the foundation for the modern theory of plate tectonics.


What year had Alfred Wegener discovered Pangaea?

Alfred Wegener had discovered pangaea in the year of 1912.


How did scientist find out about pangaea?

Scientists discovered Pangaea by studying the fit of the continents' coastlines, the distribution of fossils and rocks, and the matching geological features across continents. This evidence led to the theory of continental drift, proposed by Alfred Wegener in the early 20th century, which suggested that the continents were once part of a supercontinent called Pangaea.


How did scientist figure out that the continents were one giant continent and then separated?

Scientists discovered evidence of continental drift by observing the fit of the West African and South American coastlines, similarities in rock formations and fossils across continents, and the alignment of mountain ranges across continents. This led to the development of the theory of plate tectonics, which explains how the continents were once part of a single supercontinent called Pangaea that later separated due to the movement of tectonic plates.


What did Alexander du toit discover?

Alexander du Toit discovered evidence for continental drift in the early 20th century. He proposed that the continents were once joined together in a single supercontinent called Pangaea, and that over time they drifted apart to form the continents as we know them today. His work laid the foundation for the theory of plate tectonics.
