Wegener noticed that the continents appeared to fit together like a jigsaw puzzle, especially when looking at the Coastlines of South America and Africa. He also observed similarities in rock formations, fossils, and mountain ranges across continents that suggested they were once connected. This led Wegener to propose the theory of continental drift.

What did Alfred wegner notice about the outlines of the continents?
Alfred Wegener noticed that the outlines of the continents seemed to fit together like pieces of a jigsaw puzzle, particularly the coastlines of South America and Africa. This observation led him to develop the theory of continental drift.
Why did Wegener believe that all continents had once been joined?
Wegener believed all continents had once been joined because of the similar shapes of coastlines, matching geological formations across continents, and evidence of past glaciation extending from multiple continents, suggesting they were once connected.
Why did wegener think the continents moved?
Wegener proposed the theory of continental drift because he noticed how coastlines of continents seemed to fit together like pieces of a puzzle. He also observed similarities in rock formations, fossils, and climate across continents that suggested they were once connected. These observations led him to suggest that the continents had moved over time.
How did Wegener explain the way the continents moved?
Wegener proposed the theory of continental drift, suggesting that the continents were once connected in a single landmass called Pangaea. He proposed that the continents drifted apart over time due to the movement of the Earth's crustal plates.
Who was responsible for the idea of continents moving?
The idea of continents moving is known as the theory of plate tectonics, and it was proposed by Alfred Wegener in the early 20th century. Wegener suggested that continents were once joined together in a supercontinent called Pangaea and have since drifted apart.

What question did wegener's theory answer?
how were the continents formed
Why was the hypothesis of continental drift rejected when it was proposed by wegener?
Wegener couldn't explain how or why continents moved.
Who wrote The Origin of Continents and Oceans?
Alfred Wegener
What did wegener think the force was that was moving the continents apart?
volcanos
Who came up with the theory of moving continents?
Alfred Wegener
What did Wegener think caused the Continents to spread apart?
An earthquake.
Why did Wegener propose Millions of years ago continents were one land mass?
Wegener's theory of continental drift proved the theory of Pangea (all continents as one land mass).
Was Alfred Wegener blind?
No he was not. If he was how could he have predicted that the continents were once together
Who believed the continents were once connected but drifted apart?
Alfred wegener
Who first noticed how the continents fit together in 1911?
Alfred Wegener first proposed the theory of continental drift in 1912, in which he suggested that the continents had once been joined together in a supercontinent called Pangaea. While his ideas were not widely accepted during his lifetime, they later formed the basis for the theory of plate tectonics.
What did Wegener think happened to Pangaea?
That it split apart into the current continents.
