- 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.

∙ 12y agoThe 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.

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.

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.
Why were early explorers and cartographers fascinated by continental coastlines?
The early Spanish explorers were looking for Silver and Gold!early explorers set out to find new land for the rest of their tribesthe natives taught early explorers about how to use herbs for medicine
Why were ancient maps oriented to the east?
An east orientation was commonplace during the Middle Ages when European cartographers, guided by Christianity, oriented their maps towards the direction the sun rises and the direction of Paradise. Southern orientation (with south at the top) was common among early Arab cartographers.
Which planet has been lost from the solar system?
Many. In the early solar system, there were many more planets than there are now. Most hit joined into larger planets and a few were captured and became moons.
What is orientation on a map?
Maps are generally orientated with North at the top. The practice of orienting maps with North at the top began with Claudius Ptolemy, a Greco-Roman cartographer. In the Middle Ages, European mapmakers oriented maps with East at the top in reference to the sun rising in the east and to the believed direction of Paradise. Other cartographers, such as early Arab mapmakers, oriented their maps with south at the top.
Which suggested to early cartographers that the continents were once joined?
The shape of the continents.
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 .
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.
Which two continents' coastlines led to early suggestions that they may have joined at one time?
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 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.

Who is Alfred wegler?
Alfred Wegener was a German meteorologist and geophysicist who proposed the theory of continental drift in the early 20th century. He suggested that the continents were once joined together in a single landmass called Pangaea and have since drifted apart. Wegener's ideas laid the foundation for the modern theory of plate tectonics.

How might early cartographers have located cities mountains or rivers without latitude and longitude lines?
Early cartographers used landmarks, celestial observations, travel reports, and other geographical clues to locate cities, mountains, and rivers. They often relied on compass directions, distances between locations, and knowledge passed down through generations. Mapping was a combination of art, science, and exploration, requiring skillful interpretation and cartographic techniques.
