What did the continents look like before the continental drift?
Before the continental drift, all the continents were joined together to form a single supercontinent called Pangaea. This supercontinent began to break apart around 200 million years ago, eventually leading to the current positions of the continents.
Wegener first began to think about his continental drift hypothesis when he noticed a similarity in on different continents?
Alfred Wegener noticed that the continents looked like they could fit together like a puzzle, particularly along their coastlines. This observation led him to propose the theory of continental drift, suggesting that the continents were once joined together in a supercontinent called Pangaea.
What evidence does the continental drift have that the continents were once connected?
Evidence for continental drift includes the fit of continents like South America and Africa, similar rock formations and mountain ranges on different continents, and the distribution of fossils that were once found on now widely separated landmasses. These pieces of evidence suggest that the continents were once connected in a single landmass called Pangaea.
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 hypothesis by Alfred wegener explains why continents seem to fit togethere?
Alfred Wegener proposed the theory of continental drift, suggesting that continents were once joined together in a single supercontinent called Pangaea. Over time, the supercontinent broke apart and the continents drifted to their current positions, explaining why they seem to fit together like pieces of a puzzle.

Continental drift is supported by what evidence?
Evidence supporting continental drift includes the distribution of fossils and rock formations that match across continents, the fit of continental coastlines like puzzle pieces, and the alignment of mountain ranges and geological structures across continents. Additionally, the matching of ancient climates and glacial deposits across separate continents supports the theory of continental drift.
What can you tell by comparing the shapes of the continents with the shapes of the earth's plates?
Comparing the shapes of continents with the shapes of Earth's plates can provide insights into past plate movements. The jigsaw-like fit of continents, such as South America and Africa, indicates that they were once connected and have since drifted apart due to plate tectonics. Similar shapes of continental margins or continental shelves can suggest that they were once part of the same landmass before separating.

Evidence for continental drift?
Evidence for continental drift includes matching geological formations on different continents, such as mountain ranges and sedimentary layers. Additionally, the fit of the continents like puzzle pieces, similarities in fossil records on separate continents, and matching glacial evidence provide support for the theory. Paleoclimatic evidence, such as the distribution of ancient flora and fauna, also contributes to the case for continental drift.
What evidence does the continental drift have that the continents were once connected?
Evidence for continental drift includes the fit of continents like South America and Africa, similar rock formations and mountain ranges on different continents, and the distribution of fossils that were once found on now widely separated landmasses. These pieces of evidence suggest that the continents were once connected in a single landmass called Pangaea.
What scientific evidence supports the continental drift the theory?
Scientific evidence supporting the theory of continental drift includes the fit of the continents like puzzle pieces, matching geological features across continents, distribution of similar fossils and rocks across continents, and patterns of ancient climate change and glacial activity that align when continents are reconstructed into a single landmass. Additionally, modern techniques like GPS satellite monitoring continue to provide direct evidence of plate movements.
What does NOT support the continental drift theory?
they couldn't agree on how it separated or what made it separate.
Pieces of evidence does NOT support the continental drift theory?
the continents fit together like a puzzle
Explain the evidence for continental drift?
Evidence for continental drift includes the fit of the continents like a puzzle, similarities in rock formations and fossils across continents, and matching mountain ranges and geologic structures on different landmasses. Additionally, the distribution of certain species and climate indicators supports the theory of continental drift. These pieces of evidence suggest that the continents were once connected and have since moved apart over millions of years.
Why doesn't Pangaea look like that today?
Over millions of years, the continents have undergone significant movements due to tectonic plate interactions. The process of plate tectonics has caused the continents to separate, shift, and drift into their current positions, creating the Earth's current continental configuration. This movement has resulted in the breakup of Pangaea into the continents we see today.
What evidence supports the hypothesis of continental drift?
Evidence supporting the hypothesis of continental drift includes the fit of continents like South America and Africa, matching geological features and rock formations across continents, and similar fossil records found on separate continents. Additionally, the presence of ancient glacial deposits and the alignment of mountain ranges between continents provide further support for the movement of continents over time.
