Africa and South America. The matching Coastlines of these two continents, particularly along the Atlantic Ocean, led to the development of the theory of continental drift proposed by Alfred Wegener in the early 20th century.

What two continents coastlines led to early suggestion that they were joined at one time?
The coastlines of South America and Africa led to the early suggestion that they were joined at one time due to their similar shape, geological features, and the way certain plant and animal species were distributed across both continents. This idea eventually became known as the theory of continental drift, proposed by Alfred Wegener in the early 20th century.
Early mapmakers thought continents might have moved based on their observations of?
The fit of the coastlines of different continents, the distribution of similar fossils across continents, and the presence of similar rock formations on different continents led early mapmakers to speculate that continents may have moved over time. This gave rise to the theory of continental drift, which was later developed into the theory of plate tectonics.
Where does one early piece pieceof evidence that the continents were once joined together in a single large continents come from?
One early piece of evidence is the remarkable fit of the coastlines of South America and Africa, suggesting they were once part of the same landmass. This observation was noted by Abraham Ortelius in 1596 and later popularized by Alfred Wegener as part of his theory of continental drift.
What was it Something about a map of the Atlantic Ocean helped early geologists consider the possibility that the continents were moving.?
Early geologists noticed that the coastlines of South America and Africa seemed to fit together like puzzle pieces when examining a map of the Atlantic Ocean. This observation led to the development of the theory of continental drift, which proposed that the continents were once joined together in a single landmass and had since drifted apart.
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.
The shapes of which two continents' coastlines led to early suggestions they had been joined at one time?
Two Continents Are Africa And South America .

Which suggested to early cartographers that the continents were once joined?
The shape of the continents.
Many early mapmakers thought earth's continents had moved based on?
matching coastlines

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.

Why did Alfred wegener think that the continents were once join togrther?
Alfred Wegener proposed the theory of continental drift in the early 20th century. He observed that the continents appeared to fit together like puzzle pieces, particularly along their coastlines. Additionally, he noted similarities in rock types, fossils, and ancient climate patterns across different continents. This led Wegener to suggest that the continents were once joined together in a single supercontinent, which he called Pangaea.
What is the theory that all the continents were all one land mass at one point in history?
The theory that explains the existence of a supercontinent called Pangaea is known as continental drift. According to this theory, proposed by Alfred Wegener in the early 20th century, the continents were once joined together in a single landmass and have since drifted apart over millions of years. Geological and fossil evidence, such as matching coastlines and similar plant and animal species on separate continents, support this theory.
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 do the glossopteris fossil tell us about the early positions of the continent?
That they must have been joined up in the past because the same fossils could not exist on the continents given their current position.
