What evidence supported continental drift?
the same rock types on the edges of different continents and the reverse magnetic polarity show seafloor spreading which shows that the continents are moving. the Coastlines of South Africa and south ameria seem to match and fit together like a jigsaw and so do many other countries which gives the impression that all the continents were onced joined together as a massive continent called Pangaea
What were the three things that Alfred wegener used to prove the theory of continental drift?
Alfred Wegner had 4 theory`s,Climate evidence,Fossil evidence,the continents fitting together like a puzzle,and horizontal movement. The fossils were different types of ancient ferns and Dinosaurs.
What did wegener observe about the shapes of continental costlines?
Alfred Wegener observed that the shapes of continental coastlines, particularly those of South America and Africa, appeared to fit together like pieces of a jigsaw puzzle. This observation suggested that these continents were once connected and have since drifted apart. He used this fitting shape as part of his evidence for the theory of continental drift, which proposed that continents move over geological time. Wegener's ideas were controversial at the time but laid the groundwork for modern plate tectonics.
What are four pieces of evidence Alfred wegner used to support his theory of continental drift and why are they important?
Fit of continents: Fitting the shapes of continents together, especially the east coast of South America and the west coast of Africa. Fossil evidence: Similar fossils and rock formations found on continents separated by vast oceans. Climatic evidence: Tropical plant fossils found in regions that are currently cold, suggesting a different climate in the past. Geological evidence: Similar rock formations and mountain ranges found on different continents, indicating a common geological history. These pieces of evidence were crucial for Wegener's theory because they provided tangible support for the idea that continents were once connected and had drifted apart over time.
Why is the theory of continental drift a theory?
Tectonic plates, what the ground is on. they are always moving. Pangia, when the continents were together then "drifted" apart as time went by. Earth Quakes.... we would not have them if Tectonic plates didnt run into each other. Hence... the ground is always moving... slowly.. but surely..
Which two continents have the best fitting coastline?
Africa and South America are often cited as having coastlines that fit together like puzzle pieces. This is known as the continental drift theory, suggesting that these continents were once connected.
What is the pangaea made of?
All of the Continents fitting together i think
Alfred Wegener supported his theory of continental drift by?
Alfred Wegener supported his theory of continental drift by pointing to the fit of the continents, similarities in rock formations and fossils across continents, and evidence of past climates. Additionally, Wegener highlighted the presence of similar species on continents that were once connected.
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.
What are four pieces of evidence for continental drift?
Continents fitting together like a jigsaw puzzle, such as the matching coastlines of South America and Africa. Similar rock formations and mountain ranges found on different continents that line up when the continents are placed together. Fossil evidence of similar plants and animals found on different continents that were once connected. The discovery of mid-ocean ridges and magnetic stripes that indicate seafloor spreading and movement of continents.

What continents fit nicely together?
South America and Africa have coastlines that fit together like puzzle pieces, providing evidence of the continental drift theory. Another example is North America and Europe, particularly the eastern coast of North America and the western coast of Europe, which also show signs of fitting together.

What evidence to support continetal drift?
Evidence to support continental drift includes the fitting of continents like puzzle pieces, matching geological features and rock formations across continents that were once connected, similar fossils found on different continents, and the distribution of plant and animal species. Additionally, the discovery of mid-ocean ridges, magnetic striping on the ocean floor, and the movement of tectonic plates further support the theory of continental drift.
What Evidence such as filting together of the coast o south America and Africa supports Alfred wegeners theory of?
Alfred Wegener's theory of continental drift is supported by the fitting together of the coastlines of South America and Africa, which appear to align like pieces of a jigsaw puzzle. Additionally, geological similarities, such as matching rock formations and fossil evidence of identical species found on both continents, further bolster his argument. These findings suggest that the continents were once part of a larger landmass, which eventually split and drifted apart over time.
What would the continents fit together like?
The theory of plate tectonics suggests that the continents were once connected as a single supercontinent called Pangaea about 300 million years ago. Over time, the continents drifted apart to their current positions due to the movement of tectonic plates. If you were to fit the continents back together based on their shapes, they would fit like pieces of a jigsaw puzzle, particularly the eastern coast of South America fitting into the western coast of Africa.
