Describe continental drift theory?
continents move about as plates of crust and upper mantle, on more mobile layer of asthenophere in the mantle. Movement driven by mantle convection and isostasy. Bumps between continents = mountain chains bump continental with oceanic = island arc vocanoes and subduction of oceanic plate
Who came up with Pangaea?
A young german scientist named Alfred Wegener came up with it.Alfred Wegener of Germany.Wegener pronounced Veg-ner.He died in Iceland trying to prove his theory and is now frozen in a glacier
What is the value of a Satinwood decanter made by LeRoy Neiman?
The LeRoy Neiman commemorative decanters of Satinwood blended whiskey from 1979 came in three versions - basketball, baseball, and football. All three, in mint condition, never opened, and sold together may be worth $500-$700. For one of the three, the value is probably closer to around $100.
What do you call the lines of lead that hold a staine glass windows together?
Came.
What is the evidence missing from Alfred Wegener's continental drift theory?
The only evidence that Alfred Wegener did not have was the mechanism that drove the Continental Drift, he had evidence to support that the continents were once joined together, but did not have the means to postulate how the continents had actually moved to their present positions. He did however postulate the theory of a "layered Earth" consisting of a rigid surface (continents) upon a liquid/plastic like substance (mantle) and that if pressure was exerted on the surface layer, it would move thus, and if the pressure was removed the surface would return to its original state. It was only until c. 1890, when the Geophysicist Arthur Holmes came up with the theory of convection currents in the mantle being responsible for Continental Drift.
What period did the continents move together to form Pangaea?
Pangaea came together over a period of time spanning the Carboniferous and Permian periods. It broke up mostly during the Jurassic period.
Who came up with the theory of Pangaea?
The theory of Pangaea was proposed by Alfred Wegener in 1912. He suggested that the continents were once joined together before breaking apart and drifting to their current positions.
If the continents of Pangaea were once together how would you explain the overlaps and large gaps?
The overlaps and large gaps in the continental boundaries of Pangaea can be explained by the process of plate tectonics. Over millions of years, the Earth's crust is divided into separate plates that move and interact with each other. As these plates collided, separated, and shifted, they created overlapping areas where continents came together and gaps where they moved apart. This movement eventually led to the breakup of Pangaea into the continents we have today.
How did Pangaea form?
Five hundred million years ago, Pangaea was put together. During the centuries, Pangaea was connected numerous changes above and below the land. Soon after Pangaea, the plates under it touched then started moving away the other plates. Pangaea was a landmass that included all of the present day continents and was on this Earth for many, many millenniums.
How a earth history Pangaea formed and what is the sequence till formed continents?
Pangaea formed around 335 million years ago as all the Earth's continents came together to form a supercontinent due to the movement of tectonic plates. Over time, Pangaea began to break apart through the process of continental drift, leading to the formation of the continents we see today. The sequence of continents forming from Pangaea includes Laurasia (North America, Eurasia) and Gondwana (South America, Africa, Antarctica, Australia, India) breaking apart and drifting towards their current positions.
What is 7 continents that came from Pangaea?
they are Asia, North America, South America, Europe, Africa, Australia, and Antarctica.
How did geographers know that the first landmass on earth was called Pangaea?
Pangaea was not the first land mass It formed when the continents came together about 300 million years ago. Scientists know that there was once a single landmass based on evidence from ancient climates, fossils, rock formations found across oceans, and the behavior of tectonic plates. Scientists came up with the name Pangaea, which means "all land" in Greek, they did not discover it. Back when the continent we call Pangaea existed there were no people and thus no names.
What was Wegener's evidence that Pangaea once existed?
1. There were fossils found on different sides of continents, that were the same. 2. If you put all the continents together they fit like puzzle pices in a puzzle. Hope I helped!
Pangaea was an ancient supercontinent made up of?
It was made up of our land masses today but continental drift came and moved the continents
What is pangaea and what caused pangaea to separate?
Pangaea was a supercontinent that existed about 335 million years ago, when all the Earth's landmasses were joined together. The separation of Pangaea was caused by the movement of tectonic plates, leading to the process of continental drift. This movement continues today, with the continents slowly shifting apart.
Who came up with the name Pangaea?
The name Pangaea was coined by Alfred Wegener, a German scientist and meteorologist, who proposed the theory of continental drift in 1912. Pangaea refers to the supercontinent that existed approximately 300 million years ago and later broke apart to form the current continents.
What theory makes the occurrence of Pangaea possible?
The theory of plate tectonics makes the occurrence of Pangaea possible. According to this theory, Earth's outer layer is divided into several plates that move and interact with each other. Pangaea formed when these plates came together to create a supercontinent before eventually breaking apart into the continents we see today.
