How do scientists support the concept of plate movement through evidence and research?
Scientists support the concept of plate movement through evidence and research by studying seismic activity, mapping the ocean floor, analyzing rock formations, and observing the distribution of fossils and plant remains across continents. These methods provide data that support the theory of plate tectonics, which explains how the Earth's lithosphere is divided into large, moving plates that interact at plate boundaries.
What evidence did alfred wegener have for pangea?
Alfred Wegener had several lines of evidence to support his idea of Pangaea, including the fit of the continents, similarities in rock formations and fossils across continents, and the presence of past glacial evidence in regions that are now separated by large distances. Additionally, Wegener noted similarities in climate and geological features that suggested the continents were once connected.
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.
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.
What evidence did Wegner find that suppots the hypothesis that the Earths continents were once joined in a single large landmass?
Alfred Wegener found the following evidence to support his hypothesis of continental drift: similar rock formations and mountain ranges on different continents, matching plant and animal fossils found on separate continents, and the fit of the continents' coastlines like a jigsaw puzzle. Additionally, Wegener also noted similar geological features such as ancient glacial deposits and climate patterns that aligned when the continents were reconstructed as a single landmass called Pangaea.

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.

What evidence suggest that there was once a single super continent?
Evidence supporting the existence of a single supercontinent, known as Pangaea, includes the jigsaw-like fit of the continents along their coastlines, similarities in rock formations and mountain ranges across different continents, matching plant and animal fossils found on separate continents, and the alignment of ancient glacial deposits that suggest a single ice cap covering a large landmass. These pieces of evidence support the theory of plate tectonics and continental drift.

How were the fossil symbols and mountain belts helpful in deciding where to move the contintinents?
Fossil symbols helped in determining the past connections between continents by showing similarities in species that were now separated by large distances. Mountain belts provided geological evidence of past tectonic activity, such as where two continents may have collided. By studying these clues, scientists were able to infer the movement of continents and reconstruct past supercontinents.
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.
What are the land masses of the Earth that support life called?
The land masses of the Earth that support life are called continents. They are large, continuous areas of land that are home to diverse ecosystems and a wide variety of plant and animal species.
