What evidence do scientists have that all the continents were one large land mass?
There is evidence that the continents may have been close, because if you look at a map for the earth, it looks like the earth is a big puzzle. Saudi Arabia fits into Eurasia, South America can interlock with Africa, and if you moved all the little islands between US and Europe, the could slide in. As you can see, there is evidence that the continents may have been closer at one time.
In what ways do fossils help support the hypothesis of continental drift?
Fossils of the reptile Mesosaurus have been found in South America and Africa. It probably couldn't swim between the continents. Scientists theorized that this reptile lived on both continents when they were joined. All continents were once part of a large landmass, called Pangea, that broke apart 250-million years ago.
Large bodies of land are called what?
Continents, Islands
What are the large landmasses in the earth's oceans?
The large landmasses in the Earth's oceans are the continents. There are a total of 7 continents in the world.
How does the shape and size of the continents today help support the Theory of Continental Drift?
If you take a map and cut out all the Continent, you can see that they fit together almost perfectly, like a giant puzzle. This idea supports the fact that all the continents were connected in one large landmass.
What evidence do the scientists have to support the idea that continents were once a large landmass?
The evidence scientists have are fossil clues, plant clues, climate clues and rock clues. Fossil clues supported the idea because a certain fossil the Mesosaurus was found in two continents on opposite sides of the Earth and the only reason for that is if the lands came together at one time. Plant clues support the idea the same way fossil clues do, like the plant called a Glossopteris was found in different areas around the world. Climate clues support the idea because some of the fossils and plants from warmer climates were found in the Arctic. That explains why there are glaciers in tropical areas. Lastly rock clues support the idea because if the continents were once connected at one time, then the rocks that made up the continents should be in the same locations where they were joined.

Which of the following provides evidence that the present-day continents were once one large continent that broke apart?
The fit of the continents' coastlines, identical rock formations and mountain ranges on different continents, and the distribution of similar fossils on separate landmasses are all evidence supporting the theory of continental drift and the existence of the supercontinent Pangaea.

Scientist have found fossils of the same organism on different continents what does this suggest?
Fosssils of the same organism found on different continents support the theory of continental drift. Continents that are now separated by large oceans were once part of a single large continent.
How do scientists gather and interpret data that the earth is continually changing?
Scientists gather information that earth is continually changing by observing tectonic plate movements and studying how the layers of the crust were formed. For example, the continental drift is the idea of the continents that were all together the the years passed and the continents got separate. This idea was first suggested by Alfred Wegener in 1915. He called the single large continent Pangea. Today, there are many kinds of evidence that support continental movement. The evidence include: In 1858: Geologist Eduard Seuss points out that fossils of the Glossopteris plant were found in 5 continents and in India. Also, In 1965: Geologist Edward Bullard uses computers to match coats of South America and Africa. They match extremely well at an ocean depth of 1,000 m.
Are scientists trying to capture bigfoot?
Most scientists are not trying to capture Bigfoot. Until concrete evidence is found, it is unlikely that a large-scale trapping effort will occur.
Why is Darwin idea about natural selection considered to be a good idea?
Because there is a large body of evidence to support it.
Large bodies of land are called what?
Continents, Islands
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.
What are the large landmasses in the earth's oceans?
The large landmasses in the Earth's oceans are the continents. There are a total of 7 continents in the world.
