The evidence for continental drift included the fit of the continents the distribution of ancient fossils rocks and mountain ranges and the locations of ancient climatic zones.
What evidences support Wegener’s continental drift theory?
Wegener supported his theory by demonstrating the biological and geological similarities between continents. South America and Africa contain fossils of animals found only on those two continents with corresponding geographic ranges.
What are the 5 evidences of continental drift?
They based their idea of continental drift on several lines of evidence: fit of the continents paleoclimate indicators truncated geologic features and fossils.
What are examples of continental drift?
The Appalachians of the eastern United States and Canada for example are just like mountain ranges in eastern Greenland Ireland Great Britain and Norway. Wegener concluded that they formed as a single mountain range that was separated as the continents drifted.
Which one among the continental drift pieces of evidence mainly proves that the Cape?
Which one among the continental drift pieces of evidences mainly proves that the Cape Mountains of South America and Africa line up perfectly before? There’s equal amount of coal deposits in each continent and fossils. The evidence from the rock layers in this two continents exactly matched.
Which two pieces of fossil evidence supports the idea of continental drift?
The fossils of the reptiles Mesosaurus and Lystrosaurus and a fernlike plant called Glossopteris have been found on widely separated landmasses. This convinced Wegener that the continents had once been united. Wegener used evidence from climate change to further support his theory.
How was continental drift proven?
What is continental drift theory class 11?
Continental Drift Theory
It was proposed by Alfred Wegener in 1912. According to Wegener all the continents formeda single continental mass (called PANGAEA) and meg ocean (called PANTHALASSA) surrounded the same. He argued that around 200 million years ago the super continent Pangaea began to split.
Which three continents contain coal fields that provide evidence for continental drift?
. The answer is Eurasia North America Africa and South America. Most of the coal fields in the world are located in these countries along with good quality coal fields are found in Africa and South America.
What do the continental plates consist of?
Continental crust is composed of granitic rocks which are made up of relatively lightweight minerals such as quartz and feldspar. By contrast oceanic crust is composed of basaltic rocks which are much denser and heavier.
Which of these did not provide evidence for continental drift?
divergent. Which of these did NOT provide evidence for continental drift? oceanic plate theory. Where does sea-floor spreading take place?
When did Australia stop moving north?
Which continents were obviously neighbors before?
Q18: Which continents do you think were neighbors before? North America Europe and North Asia were once neighbors because they made up the Laurasia. On the other hand Africa South Asia Antarctica Australia and South America were once neighbors because they were the ones that made up the Gondwanaland.
What did Harry Hammond Hess realize in the 1950s?
Hess discovered that the oceans were shallower in the middle and identified the presence of Mid Ocean Ridges raised above the surrounding generally flat sea floor (abyssal plain) by as much as 1.5 km.
Which best supports the idea of continental drift?
Which best supports the idea of continental drift? Fossilized remains of the same plants and animals are found on different continents. … The continents of the Earth are continually moving. Fossilized dinosaur eggs have been found in the third of five rock layers during fossil dig.
What are the evidences of plate movement found in your constructed Pangaea?
What are the lines of evidence that Alfred Wegener used to support the idea of continental drift Why did scientists of his day doubt that continents drifted?
Why did scientists of the time doubt that continents had drifted? Although the evidence in support of continental drift seems compelling scientists in Wegener’s time rejected the idea of continental drift because the mechanisms Wegener proposed as driving continental movement seemed too far-fetched to be plausible.
What did Alfred Wegener discover?
Alfred Wegener proposed the theory of continental drift – the idea that Earth’s continents move. Despite publishing a large body of compelling fossil and rock evidence for his theory between 1912 and 1929 it was rejected by most other scientists.
Who proposed the theory of continental drift explain any four evidences in support of it?
What is continental drift theory and what were the major evidences of the theory evaluate the theory with recent discoveries?
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.
What is continental drift Class 10?
The theory of continental drift points out that the Earth’s continents are constantly drifting away from each other. According to this theory: all the continents were one single continental mass (called a Super Continent) – Pangaea. … Our continents are located on these plates. These plates are always moving around.
Which three continents contain coal fields that provide evidence for continental drift Africa Antarctica and North America?
Check all that apply. Which continents contain coal fields that provide evidence for continental drift?
Which source of evidence did Wegener use to support his theory of continental drift fossils magnetic fields satellite mapping warm equatorial climates?
Wegener used fossil evidence to support his continental drift hypothesis. The fossils of these organisms are found on lands that are now far apart. Wegener suggested that when the organisms were alive the lands were joined and the organisms were living side-by-side.
Which continents contain fossils of Glossopteris?
Glossopteris ferns had very heavy seeds that could not move by wind or drift on ocean currents. Fossils have been found on all the southern continents – Australia Antarctica India South Africa and South America.
What are the 4 types of plate boundaries?
- Convergent boundaries: where two plates are colliding. Subduction zones occur when one or both of the tectonic plates are composed of oceanic crust. …
- Divergent boundaries – where two plates are moving apart. …
- Transform boundaries – where plates slide passed each other.
What are the 4 types of plate tectonics?
There are four types of boundaries between tectonic plates that are defined by the movement of the plates: divergent and convergent boundaries transform fault boundaries and plate boundary zones.
What are 2 continental plates?
What are 6 pieces of evidence that support continental drift?
The four pieces of evidence for the continental drift include continents fitting together like a puzzle scattering ancient fossils rocks mountain ranges and the old climatic zones’ locations.
What is the best piece of evidence for plate tectonics?
Answer: Modern continents hold clues to their distant past. 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.
What evidence supports the idea that all the continents were once joined together?
In the early part of the 20th century scientists began to put together evidence that the continents could move around on Earth’s surface. The evidence for continental drift included the fit of the continents the distribution of ancient fossils rocks and mountain ranges and the locations of ancient climatic zones.
Will Australia and Asia collide?
Which direction has Africa drifted?
It has been moving over the past 100 million years or so in a general northeast direction. This is drawing it closer to the Eurasian Plate causing subduction where oceanic crust is converging with continental crust (e.g. portions of the central and eastern Mediterranean).
Is New Zealand moving which way how fast?
Which way are New Zealand’s plates moving and how fast? The Australian Plate is moving north and the Pacific Plate is moving west but of course the plates are moving on a sphere not a flat surface. … The Pacific Plate moves on average 3-4cm/year (30- 40mm/year).
