Is Pangea a fact?
From about 280-230 million years ago (Late Paleozoic Era until the Late Triassic), the continent we now know as North America was continuous with Africa, South America, and Europe. They all existed as a single continent called Pangea.
Why is Continental Drift rejected?
This idea was quickly rejected by the scientific community primarily because the actual forces generated by the rotation of the earth were calculated to be insufficient to move continents.
Which statement is true about the theory of plate tectonics and the theory of continental drift?
Q. Which statement is true about the theory of plate tectonics and the theory of continental drift? The theory of plate tectonics explains how continental movements could occur. The theory of plate tectonics shows that continental movements could not have happened.
Which would Subduct if the two were to collide with each other?
Oscar L. Continental plates contain less dense rocks than oceanic ones, so the continental plates are more buoyant and the oceanic plates will subduct uopn collision.
Do two colliding continental plates always cause volcanoes?
Volcanoes more often occur from the collision of an oceanic plate and a continental plate rather than two continental plates.
When two plates separate at a divergent boundary creates new crust?
A divergent boundary occurs when two tectonic plates move away from each other. Along these boundaries, earthquakes are common and magma (molten rock) rises from the Earth’s mantle to the surface, solidifying to create new oceanic crust.
Where are the continental plates?
A continental plate is exemplified by the North American Plate, which includes North America as well as the oceanic crust between it and a portion of the Mid-Atlantic Ridge. The latter is an enormous submarine mountain chain that extends down the axis of the Atlantic basin,…
What is the largest continental plate?
Pacific Plate
