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 usgs stand for and what do they do?
The United States Geological Survey/service were and are the cartographers that converted early maps into the GPS location system known today.
Material that melted to form the early continents was what?
Rock
Oparin's hypothesis suggested that early Earth's atmosphere lacked what?
oxygen
Tectonic plates that move apart most likely are loacted along?
Continents because the continents were together before when the earth was in its early stages then every thing separated so therefore the answer is continents

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.
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 suggested to early cartographers that the continents were once joined?
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.

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.
