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 ground
The answer is simply Thermal convection
I dont know what it is but it is not that. I am doing a word cross puzzle and it says it is 17 letters
The correct answer for your crossword puzzle is thermal convection

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.
Subduction occurs where the oceanic crust bends down toward the mantle at a(n)?
Seafloor spreading occurs along mid-ocean ridges. Mid-ocean ridges are large mountain ranges on the ocean floor. The shifting in the rock causes the seafloor to spread and allows magma to bubble and form more mountains on the ocean floor.
How would the age of the oldest rock on the continents compare with the age of the oldest rock on the seafloor?
The sea floor is young (the rocks are made at the mid oceanic ridges and spread out form there) while most of the continental rocks are older. This is because the continental crust floats on top of the oceanic crust and is therefore not recycled.
What is the name of the theory that explains how forces within the earth can cause ocean floor to spread and continents to move?
Theory of plate tectonics explains how forces deep within earth can cause ocean floors to spread and continents to move
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 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.
