Wegener's theory of continental drift proposed that the continents were once joined together in a single supercontinent called Pangaea. Over time, the continents drifted apart to their current positions. This idea eventually led to the development of the theory of plate tectonics, which explains the movement of Earth's lithosphere on the underlying asthenosphere.

What are wegeners clues of the jigsaw puzzle?
Wegener's clues for the theory of continental drift included the fit of the continents like a jigsaw puzzle, matching rock formations and mountain ranges across continents, and similarities in plant and animal fossils found on different continents. These clues provided evidence for the movement of the continents over time.
What is the fit of continents?
The fit of continents refers to the idea that the coastlines of continents appear to fit together like puzzle pieces. This observation played a key role in the development of the theory of continental drift and plate tectonics by Alfred Wegener in the early 20th century.
What 2 continental have the most obvious fit of the coastlines?
The continents with the most obvious fit of coastlines are Africa and South America. This is known as the theory of continental drift, where it is believed that these continents were once connected as part of the supercontinent Pangaea. The coastlines of these two continents appear to fit together like pieces of a puzzle, providing evidence for the theory of plate tectonics.
What is the fit of the continents called?
The fit of the continents is called continental drift, which refers to the theory that Earth's continents were once all connected in a single supercontinent called Pangaea, before breaking apart and moving to their current positions.
Who obsered that the continents seem to fit together?
Alfred Wegener, a German meteorologist and geophysicist, proposed the theory of continental drift in the early 20th century based on the idea that the Earth's continents appeared to fit together like pieces of a jigsaw puzzle. This laid the foundation for the development of the theory of plate tectonics.
Wegeners hypothesis of continental drift was replaced in 1967 by which theory that supported his idea continents move?
plate tectonics
Which observation supported Wegeners theory of continental drift?
The fit of the continents like pieces of a puzzle, similarities in rock formations and fossil records across continents, and the matching geological structures on opposite sides of the Atlantic Ocean all supported Wegener's theory of continental drift.
What are wegeners clues of the jigsaw puzzle?
Wegener's clues for the theory of continental drift included the fit of the continents like a jigsaw puzzle, matching rock formations and mountain ranges across continents, and similarities in plant and animal fossils found on different continents. These clues provided evidence for the movement of the continents over time.
Why did other scientists not accept Alfred Wegeners theory?
why did other scientist not accpet Alfred Wegeners theory
Does fossils support wegeners theory?
Yes, because he found fossils from a fresh water lizard, in two different continents separated by salt water.

What was Alfred wegeners evidence?
Alfred Wegener's evidence for the theory of continental drift included matching coastlines on different continents, similar rock formations and mountain ranges across continents, and the presence of identical fossils on separate continents. He also noted the jigsaw-like fit of South America and Africa and the distribution of climatic zones in ways that made more sense if the continents were once connected.
What was the fatal weakness in wegeners theory?
One of the fatal weaknesses in Wegener's theory of continental drift was the lack of a plausible mechanism to explain how continents could move through the solid rock of Earth's mantle. Additionally, Wegener was unable to adequately explain what forces could be responsible for moving the continents.
What is the fit of continents?
The fit of continents refers to the idea that the coastlines of continents appear to fit together like puzzle pieces. This observation played a key role in the development of the theory of continental drift and plate tectonics by Alfred Wegener in the early 20th century.
What was wegeners theory called?
Alfred Wegener's theory was called the theory of continental drift. He proposed that the continents were once joined together in a single supercontinent called Pangaea, which later broke apart and drifted to their current positions.
What evidence did Wegeners have to support his theory?
Fossils support his hypothesis.
What were Charles Darwin's contributions to Wegeners theory of continental drift?
Most people actually state that Darwin beat Wegener to the theory of continental drift as he mentioned in most of his studies about the continents drifting apart and fitting together.
