Are the continents moving?
The continents are moving when they spread apart
What convinced scientists that Wegener's theory of continental drift was true?
While Wegner's theory of continental drift assumed that continents plowed through and over oceanic crust, his basic ideas are still upheld today. As a result of submarines and radar technology used in WWII, scientists were better able to map the seafloor. In doing so they discovered the seafloor's topography, age, magnetism, and the Mid-Atlantic Ridge. After discovering that the seafloor did spread apart and that continents moved, Wegner's theory gradually became accepted.
What is the primary force that cause the seafloor to spread and continental to drift?
Contintal plates
When the continents separated some of the same species ended up on a different continents this was due to?
The continents used to all be connected, which means animals were free to roam. If they were free to roam, then they obviously spread out throughout the continent. So when this continent separated, the same species ended up on new continents because they had originally spread out.
What force causes the seafloor to spread and continents to drift?
Originally conceived as "continental drift," the theory of plate tectonics explains the motion of Earth's landmasses. However, there is still much debate as to what drives this motion. Explanations include upper mantle convection currents, forces due to gravity, and the effect of the Earth's rotation.
Are the continents moving?
The continents are moving when they spread apart
What primary force that causes the seafloor to spread and continents to drift?
Geothermal Drift.
What is a seventeen letter word for a primary force that causes the seafloor to spread and continents to drift?
thermal convection
The primary source that causes the seafloor to spread and continents to drift?
In the middle of the ocean is a rift where the ocean floor squeezes out lava and pushes the ocean plates apart.
What happened to the joined continents?
They were spread apart over a period of time when the earth's crust was moving.
What causes the seafloor to spread?
rising molten magma

What is Russia continents?
it is spread across 2 continents of Asia and Europe.

Contintal plates
What phenomenon occurs as a result of seafloor spreading?
In 1960, seafloor spreading was hypothesized by Harry Hess of Princeton University. Seafloor spreading occurs at divergent boundaries and it is said to be the mechanism that operates along the oceanic ridge system to generate new seafloor. Thus, the result of seafloor spreading is the creation of new sea floor through the uplift of magma: magma raises from asthenosphere, new oceanic lithosphere moves from ridge, and it thickens, cools (becomes denser), and subsides.
What are the evidences of the movents of the continents?
The evidence that the continents are moving today is actually just a theory, but is accepted to be true. This theory is known as Continental Drift and is described as the continents belonging to tectonic plates, which are basically floating on the Earth's surface. Evidence to prove such is that the continents all fit together like a jigsaw puzzle and related or the same plant or animal species are located on separated continents, suggesting that they were all once connected to allow the animals to roam and the plants to spread. If they have moved in the past, they must still be moving today, and there are projected paths the continents are taking.
The primary force that causes the seafloor to spread and continents to drift?
It would have to be continental drift because the plates are moving in the lithosphere causeing the magma to come up 7 killometers from the groundThe answer is simply Thermal convectionI dont know what it is but it is not that. I am doing a word cross puzzle and it says it is 17 lettersThe correct answer for your crossword puzzle is thermal convectionCheesecakeshes right:) the cheesecake person also doin a crossword puzzel
