In the theory of continental drift, a single land mass refers to the supercontinent known as Pangaea, which existed about 335 million years ago. Pangaea eventually broke apart into the continents we recognize today, driven by the movement of tectonic plates. This concept, proposed by Alfred Wegener, suggests that continents were once joined together and have since drifted to their current positions.

What was the fossil that was found on different continents and was used to support the theory of continental drift?
The fossil that was found on different continents and used to support the theory of continental drift is the Mesosaurus. This extinct freshwater reptile had limited swimming abilities, making it unlikely that it could have crossed vast oceans. Its distribution on both sides of the Atlantic Ocean provided evidence of land connections that later formed the basis for the theory of continental drift.
What was the theory of all land mass was once connected at a point called?
The theory that all land masses were once connected at a point called "Pangaea" is known as the theory of continental drift. This theory suggests that continents have moved over geological time due to plate tectonics.
What theory explained how earth was once a single?
The theory that explains how Earth was once a single supercontinent is called the "Theory of Plate Tectonics." This theory suggests that Earth's outer shell is divided into several plates that move and interact with one another over time, causing continents to drift apart or come together. The supercontinent that is believed to have existed in the past is known as Pangaea.
What is a good sentence for continental drift?
The term 'continental crust' is a compound noun, a word for therelatively thick part of the earth's crust that forms the large landmasses. A noun functions in a sentence as the subject of a sentence or a clause, and as the object of a verb or a preposition. Examples:Bobby has no idea what a continental crust is. I explained to him that continental crust is land (territory).
What is the idea of Hess Wagner and others emphasize the earth is dynamic planet and how is the sea floor spreading different from continental draft?
Continental drift is the hypothesis that states that the continents once formed a single land
What is the name given to the land in the continental drift theory?
Pangia
Theory that the continents were once joined joined as one large single land mass?
The theory is called continental drift, proposed by Alfred Wegener in the early 20th century. It suggests that at one point in Earth's history, all continents were connected into a single supercontinent called Pangaea. Over millions of years, the continents drifted apart to their current positions.
Wegener's theory of what says that land masses move slowly?
Wegener's theory of continental drift posits that land masses on Earth move slowly over time due to the shifting of tectonic plates. This movement has caused the formation of continents as we know them today.
Is it true or false that continental drift continents were joined together to form a large land mass?
True, the theory of continental drift proposes that continents were once joined together in a single supercontinent called Pangaea. Over millions of years, the continents have moved apart to their current positions.
What is the hypothesis that proposed that earths continents were once joined in a single land mass?
The hypothesis that proposed that Earth's continents were once joined in a single land mass is called continental drift. This theory, formulated by Alfred Wegener in the early 20th century, suggested that the continents were once part of a supercontinent called Pangaea that later broke apart and drifted to their current positions.
What was used to dispute continental drift?
Continental drift is a concept relating to the movement of the Earth's continents. The proving of the continental drift theory came from evidence found around the world. Foremost, scientists had discovered that similar plants and animal fossils were found in or around different continents, suggesting that they were once joined. The theory of plate tectonics also supported continental drift. If one were to look at a global map, the complementary arrangements between South America and Africa can be easily seen.
Why did Wegener propose Millions of years ago continents were one land mass?
Wegener's theory of continental drift proved the theory of Pangea (all continents as one land mass).
What is the Alfred wegener known for?
he thought that the continents used to be one big continent and the plates underground broke and mad our continents todayAnother of his theories was that the continents are moving. He was ridiculed by the scientific community because they thought that the continents were always like this. Wegener's evidence for this was that matching fossils were in south America and also in Africa Other scientist reckoned it was a land bridge connecting the two continents even though there was no evidence for a land bridge. Also was the jigsaw-fit of the continentsWegener's theory is Continental drift- The Earth once had a single landmass that broke up into large pieces, which have since drifted apart.
Wegener called the large landmass in his theory of continental drift?
Wegener called the whole land mass of land "Pangaea".not too sure but i think it means entire Earth . They were all at the southern hemisphere and then drifted away and finally came to the place hwere they currently are , this is Wegener's continental drift theory .
Does continental drift cause new land?
Yes, it can cause new land if an underwater volcano erupts due to Continental Drift, and the lava goes hard.
How does the Petoskey Stone help prove the Theory of Continental drift?
It is another example that helps scientists with their theory that all of Earth's landmasses (land) were/was once connected. WOOOOOOOOOT WOOOOOOOOOOT
Scientist have found fossils of the same organism on different continents what does this suggest?
The discovery of fossils of the same organism on different continents suggests that these landmasses were once connected as part of a single supercontinent. This supports the theory of plate tectonics, which explains the movement of Earth's lithosphere. The distribution of these fossils provides evidence for the movement of species across land bridges or through continental drift over millions of years.
