- The continent pieces fit together as if they where a puzzle. If you look at South America and Africa it seems that they could have once been connected.
- Fossil evidence in different countries implies that they may have once been joined. The fossils of large birds are the same implying that there was a common ancestor to large flightless modern birds that are separated on different continents.
- Mid ocean ridges are spreading the ocean floors apart. The age of the rocks on the bottom of the ocean shows that the plates that the continents are on are moving apart.
- Finally, the most compelling evidence is to do with the magnetism of the rocks. As the lava cools the ferromagnetic material in some rocks lines up with the Earth's magnetic poles. When these rocks move they are no longer lined up to the Earth's current magnetic poles, they produce anomalies in the magnetic readings. These rocks reveal their latitude of where they were when they cooled.
Similarities in the shape of Coastlines and the presence of identical fossils and rock formations on different continents suggested to early cartographers that the continents were once joined together. This concept eventually led to the development of the theory of continental drift by Alfred Wegener in the early 20th century.
The shape of the continents and the way they could fit together best suggests the formation of supercontinents in the past. Also, the distribution of biodiversity gives us information on which continents were joined and at what point they diverged.
The fact that the continents are still moving. Tools have been set up to monitor plate movement over decades, and scientists have done the math to figure out when the continents were touching. They know movement didn't start sooner because they know that convection currents in the mantle cause plate movement.
One piece of evidence that indicates the continents were once connected is the shape of the continents. Many of the continents look as if they fit together like a puzzle.
The first evidence that led people to think that the continents were once connected because of earthquakes
plate tectonics, it shows how the continents moved and how they were connected.
The continents fit together like a jigsaw puzzle. And also by shape of continents
The Big Bang Theory was proof that all continents were once joined together and then was an explosion.
Which of the following are geologic evidence that support the hypothesis that the eastern coast of North America was once joined with the western coast of Europe?

Who was the first one who studied the continental drift theory?
Alfred Wegener, a German meteorologist and geophysicist, was the first to propose the theory of continental drift in the early 20th century. He suggested that the Earth's continents were once joined as a single landmass called Pangaea and later drifted apart to their current positions.
What do the glossopteris fossils tell us about the early position of the continents?
shows that all three continents were once connected (joined) together. because the 'exact' same fossil types were found in all three different continents, which are now split from each other.
What scientist is known for proposing the idea of moving tectonic plates?
Alfred Wegener, a German meteorologist and geophysicist, is known for proposing the theory of continental drift in the early 20th century. This theory suggested that the Earth's continents were once joined in a single supercontinent called Pangaea and have since moved apart, leading to the concept of tectonic plates and plate tectonics.
Who believed the continents were once connected but drifted apart?
Alfred Wegener, a German meteorologist and geophysicist, proposed the theory of continental drift in the early 20th century. He suggested that continents were once part of a single supercontinent called Pangaea and gradually drifted apart over time.
Who first noticed the puzzle like fit of the continents?
Alfred Wegener, a German meteorologist and geophysicist, first proposed the theory of continental drift in the early 20th century. He noticed the puzzle-like fit of the continents, suggesting that they were once joined together in a single landmass he called "Pangaea."
Which suggested to early cartographers that the continents were once joined?
The matching coastlines or jigsaw puzzle-like fit of the continents, as well as the fossil and rock formations that span across continents, suggested to early cartographers the concept of continental drift or the idea that the continents were once joined together in a single supercontinent. This idea eventually led to the development of the theory of plate tectonics.
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 is the hypothesis that proposed that earths continents were once joined in a single land mass?
The hypothesis that proposed that Earth's continents were once joined in a single land mass is called continental drift. This theory, formulated by Alfred Wegener in the early 20th century, suggested that the continents were once part of a supercontinent called Pangaea that later broke apart and drifted to their current positions.
Which explorer had two new continents named after himself?
Amerigo Vespucci had two continents, North America and South America, named after him. Although he did not discover these continents, his name was used by cartographers in the early 16th century in their maps.
Who formed the hypothesis that earths continents move?
Alfred Wegener was a German scientist who first proposed the hypothesis of continental drift in the early 20th century. He suggested that the continents were once joined together in a single landmass called Pangaea and had drifted apart over millions of years.
What man saw the continents fit together?
Alfred Wegener proposed the theory of continental drift in the early 20th century. He suggested that the continents were once joined together in a single supercontinent called Pangaea and have since drifted apart. This idea eventually led to the development of the theory of plate tectonics.
What is the huge landmass in which all continents were once joined?
The supercontinent that all continents were once joined to is called Pangaea. It existed during the late Paleozoic and early Mesozoic eras before breaking apart into the continents we know today.
Who found pangea?
Alfred Wegener, a German scientist, proposed the theory of Pangaea in the early 20th century. He suggested that Earth's continents were once joined together as a supercontinent called Pangaea, which later broke apart and drifted to their current positions.
Who is the scientist said that the continents were once a whole?
Alfred Wegener, a German meteorologist, is most famously credited with proposing the theory of continental drift in the early 20th century. He suggested that the continents were once joined together in a single supercontinent called Pangaea and gradually drifted apart over millions of years.
What was Arthur Holmes theory o drifting continents?
Arthur Holmes proposed the theory of continental drift in the early 20th century. He suggested that the continents were once joined together in a supercontinent called "Pangaea" and have since drifted apart due to the movement of the Earth's tectonic plates. Holmes' hypothesis laid the groundwork for the modern theory of plate tectonics.
Theory that the continents were once joined joined as one large single land mass?
The theory is called continental drift, proposed by Alfred Wegener in the early 20th century. It suggests that at one point in Earth's history, all continents were connected into a single supercontinent called Pangaea. Over millions of years, the continents drifted apart to their current positions.
What do the glossopteris fossils tells us about the early position of the continents?
That they must have been joined up in the past because the same fossils could not exist on the continents given their current position.
