How was the theory of continental drift strengthened by discoveries of closely related earthworms on widely separated continents?
The continental drift theory was strengthened by several discoveries of similar species on widely separated continents. The basic idea was that if Continent A, say, Africa, had a fossil of a certain worm on its west coast, while Continent B, South America, had a fossil of the same worm on its eastern coast, it would only make sense that at one time these continents had to be joined to allow for this species to flourish in both areas at once. The only other possible explanation would be that the worms swam across the ocean...which isn't exactly feasible considering that they are, in fact, worms.
How do scientists know about continents once existing of landmasses?
There are two main evidences for this: 1. The continents fit together like a puzzle 2. There are both extant and extinct animal and plant species present on several continents that are not connected
What are the contanants?
A continent is several large landmasses on the Earth. They are larger than island and there are seven continents on the Earth.
What does pangaea and tectonics mean in latin?
Pangea meaning "all lands" was the name given to the single super continent by Alfred Wegner, the originator of the theory of continental drift. Pangea broke into several smaller continents that subsequently drifted away from each other. Tectonic is relating to, causing, or resulting from structural deformation of the earth's crust.
Give an example of evidence from land features that supported wegeners idea of continetal drift?
There are several pieces of evidence from land features which support Wegener's idea of continental drift. One example is that if you line up the maps of South America and Africa you will see that the mountain ranges line up, which is strong evidence that the two continents were once one.
The presence of the same on several continents supports the hypothesis of continental drift.?
Similar fossils on several continents supports the theory of continental drift. The same animal fossils, or similar ones have been found on many continents supporting the Pangea theory.
What evidence is there that all of the continents use to be joined?
The evidence for the theory of continental drift comes from several sources, including the fit of the continents like pieces of a jigsaw puzzle, similarities in rock formations and fossils across different continents, and matching geological features such as mountain ranges. Additionally, paleoclimatic evidence, like the presence of glacial deposits in regions that are now near the equator, supports the idea that the continents were once joined in a supercontinent called Pangaea.
Are the continents on top of the earth's plates?
A continent is what floats on top of the plate. There are continental and oceanic plates. The continents float on the continental plate and the ocean sits on the oceanic plate. But there are also plates that carry both continents and oceans. The plates are what causes continental drift. So basically plates are what carry the continents and oceans.
Evidence for continental drift?
The existence in the fossil record of the same land species on several continents. Since these animals are not seafaring then the continents must have been connected at one time. Also continental drift is supported by vast empirical evidence.
Does the existence of intermediate forms support or not support the theory of evolution?
Intermediate forms are predicted by evolutionary science in several ways. Their presence supports the theory of evolution.
What did Alfren Wegener present as evidence that the continents move?
Alfred Wegener presented several lines of evidence to support his theory of continental drift, including the fit of the continents like a jigsaw puzzle, similarities in rock formations and mountain ranges across continents, and the distribution of fossils of the same species on different continents separated by oceans.
What is the idea called that said the continents have moved over time?
The idea is called plate tectonics, which proposes that Earth’s lithosphere is divided into several large plates that move and interact with each other, causing phenomena like earthquakes and the shifting of continents over geologic time scales.
Are there any wrist supports that prevent wrist pain when bodybuilding?
There are several options of wrist supports that can be used when bodybuilding. The Live strong website has several supports to choose from. They are great products with great reviews.
Is continental drifting a cause of climate change?
In the past climate change has been a very short-term thing compared with continental drift. The have been several ice-ages in the last 100,000 years, and the continents have drifted imperceptibly in that period. On a scale of 100s of millions of years then continents drifting towards or away from the poles will of course see very slowly changing climate over that very long period.
Are all plate boundaries located along the margins of continents?
No. Many plate boundaries are on the seafloor far from continents and several are well within continents.
What hypothesis says that all the continents once were joined as a single supercontinent and have since drifted apart?
this supercontinent is called PANGEA. it is the greek word for "all lands".
Does earth's surface stay the same?
No, the surface changes. Erosion from rain and wind will gradually make mountain ranges lower; continents move; this movement creates new mountains, as the continental plates push against each other. For example, several million years ago, most continents were together, in one supercontinent, "Pangaea". I suggest you read an encyclopedia (e.g., en.wikipedia.org) article about plate tectonics; also about Pangaea or Pangea.No, the surface changes.
