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.
How can it be that fossil fern plants found in Polar Regions today and fossils found on the east coast of South America are identical to those found on the west coast of Africa?
even thought all the continents you see today used to be all together in a land called Pangea.then the continental plates shifted and there you find fossils from the polar regions identical to the coast of africa...
What fossils prove continental drift true?
Fossils of similar plants and animals found on separate continents, such as the Mesosaurus and Glossopteris, provide evidence for continental drift. Additionally, matching geological formations and mountain ranges on different continents support the theory of continental drift. Magnetic striping on the ocean floor also supports the movement of continents over time.
Why part of the east coast of south america and the west coast of africa have matching fossils within the same series of rock layers this provides evidence that these two continents were once?
No
What are 3 types of evidence that support Pangaea?
Fossil evidence of similar plant and animal species found on different continents. Geological evidence of matching rock formations and mountain ranges on different continents. Climate evidence, such as glacial deposits and ancient climate patterns, that suggest continents were once connected.
What types of evidence did Wegner have to the idea of Pangaea?
1. The continents look like puzzle pieces that should fit together (maybe they did in the past). 2. Fossils and geographic layers found on the coast lines of continents (especially South America and Africa) matched up.
What is found off the east coast of all continents?
The Atlantic Ocean is found off the east coast of all continents.
What evidence is there along Africa and America to suggest the continents were once attached?
Fossil evidence, such as similar plant and animal species found on both continents, as well as rock formations that match up when the continents are reconstructed into a supercontinent called Pangaea, suggest that Africa and America were once connected. Additionally, the discovery of similar geological features, such as mountain ranges and coastlines, along the western coast of Africa and eastern coast of South America provides further support for this theory.
What are three things that scientist use to support the theory of continental drift?
Fossil evidence of similar species found on different continents, suggesting that they were once connected. Matching geological formations and rock layers on different continents that fit together like puzzle pieces. The similarities in coastlines and mountain ranges between continents, particularly the east coast of South America and west coast of Africa.
What South American country has the longest coast line on the continents west coast?
Chile
What can you infer about the area where you find a pecten fossil?
Pecten fossils are mostly found on the east coast of the United States.
Why Wegener interested in finding fossils of the same plants and animals on two different continents?
The answer is quite simple. Millions and billions of years ago, the Earth was one land. This was called Pangea. However, due to plate techtonics, they move the land around and over time, these lands split apart. After enough time has elasped, these gaps would become oceans. For example, when the continents were together as pangaea the animals roamed freely, but when they split apart the animals were split up. So a plant or animal fossil may be the same on the eastern coast of South America as it is on the western coast of Africa.
