Often asked: How Were The Fossil Symbols And Mountain Belts Helpful In Deciding Where?

How were the fossils symbols and mountain belts helpful in deciding where to move continents?

How were the fossil symbols and mountain belts helpful in deciding where to move the continents? They made it a lot easier to see where to put the pieces. Otherwise, it was really hard to fit them all together. It suggests that when the continents broke up the reptiles continued to exist on their new landmasses.

How did continent shape help in deciding where to place the continents which two continents have the most obvious fit of the coastlines?

Two continents have the most obvious fit of the coastlines are the east coast of South America and the west coast of Africa, because the east coast of South America and the west coast of Africa seem to fit together like pieces of a jigsaw puzzle. Wegener discovered that their rock layers are fit just as it clearly.

How did Wegener explain similar fossils on different continents?

Continental drift was a theory that explained how continents shift position on Earth’s surface. Set forth in 1912 by Alfred Wegener, a geophysicist and meteorologist, continental drift also explained why look-alike animal and plant fossils, and similar rock formations, are found on different continents.

Which 2 continents have the most obvious fit?

Which 2 continents have the most obvious fit of the coastlines? South America and Africa has the most obvious fit of the coastlines.

Which fossil occurs on the most landmasses Pangea?

The Glossopteridales (Glossopteris fossils ) occur on the most landmasses. Their distribution across several detached landmasses led scientists to believe that these were once merged into a single supercontinent, Pangea.

Which fossil occurs on most of the landmasses What does this suggest about when these continents broke up?

The Glossopteridales occurs on most landmasses. This suggests that the continents were once merged into supercontinents.

What are 3 pieces of evidence for Pangea?

Alfred Wegener, in the first three decades of this century, and DuToit in the 1920s and 1930s gathered evidence that the continents had moved. They based their idea of continental drift on several lines of evidence: fit of the continents, paleoclimate indicators, truncated geologic features, and fossils.

What is the evidence of Pangea?

The rock formations of eastern North America, Western Europe, and northwestern Africa were later found to have a common origin, and they overlapped in time with the presence of Gondwanaland. Together, these discoveries supported the existence of Pangea.

Why do the continents not fit together exactly?

Wegener suggested that perhaps the rotation of the Earth caused the continents to shift towards and apart from each other. (It doesn’t.) Today, we know that the continents rest on massive slabs of rock called tectonic plates. The plates are always moving and interacting in a process called plate tectonics.

What is the best piece of evidence for plate tectonics?

Evidence from fossils, glaciers, and complementary coastlines helps reveal how the plates once fit together. Fossils tell us when and where plants and animals once existed. Some life “rode” on diverging plates, became isolated, and evolved into new species.

What was the name of the supercontinent?

Pangea, also spelled Pangaea, in early geologic time, a supercontinent that incorporated almost all the landmasses on Earth.

What was the response to Wegener’s hypothesis?

In 1912, Alfred Wegener proposed a theory that the continents had once been joined, and over time had drifted apart. This was the Continental Drift Theory. The reaction to Alfred Wegener’s theory tells us much about the workings of science. We are taught that modern scientists are driven only by reason and facts.

Which two continents have the most obvious fit Pangea?

Answer Expert Verified. The East coastline of South America and the west coastline of Africa share the most obvious fit, it gave Wegener the first idea as evidence for the continental drift.

Are the continents a perfect fit?

The shapes of continents fit together like a puzzle. Just look at the east coast of South America and the west coast of Africa—it’s almost a perfect fit! Identical rocks have been found on different continents. These rocks formed millions of years ago, before the continents separated.

How did the fossil evidence help you to put the landmasses together?

Alfred Wegener collected diverse pieces of evidence to support his theory, including geological “fit” and fossil evidence. This indicates that these continents had to be once joined together because the extensive oceans between these land masses act as a type of barrier for fossil transfer.
