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.

Sea-floor spreading is a result of?
Seafloor spreading occurs when two tectonic plates move further away from each at mid-ocean ridges. In these ridges new crust is formed through volcanic activity and thus expanding the seafloor.
Could a large lake recede before an earthquake occurs?
Yes, it could. This phenomenon was observed before the Alaskan earthquake of 1964. It can happen as a result of the lake basin tilting prior to the quake.
What does divergent result in?
It results in sea floor spreading.
Where does spreading center volcanism occur?
Spreading-center volcanism is associated with basalt. It is a type of intrusive igneous rock that sometimes exhibits a columnar structure.
Use the words sea floor spreading and mid ocean ridges in a complete sentence?
Mid ocean ridges are the direct result of sea floor spreading.
What is least likely to result from seafloor spreading?
bananas :~P

When solid mantle rock rises during seafloor spreading magma is produced as a result of decompression melting?
Yes.
Is the following sentence true or false when solid mantle rock rises during seafloor spreading magma is produced as a result of decompression melting?
true
What type of formation is a mid-oceanic ridge?
Its mostly a basaltic formation, caused as a result of ferromagnetic magmatic emergence at zones of seafloor spreading during oceanic-oceanic divergence.
Nuclear medicine what is the glove phenomenon?
The glove phenomenon is usually the result of arterial injection of a radiopharmacon.
Could a large lake recede before an earthquake occurs?
Yes, it could. This phenomenon was observed before the Alaskan earthquake of 1964. It can happen as a result of the lake basin tilting prior to the quake.
The allee effect is a phenomenon that occurs when population size?
The allee effect is a phenomenon that occurs when population size decreases, leading to decreased reproduction or survival rates. This can result in a feedback loop where the population spirals towards extinction. Efforts to prevent the allee effect may involve conservation strategies that increase population size or enhance reproductive success.
What physical feature is created when the seafloor spreads?
A mid-ocean ridge is formed along a line created by sea floor spreading. It usually consists of parallel mountain ranges separated by a valley. Sea floor spreading is the result of plate tectonics, where two crustal plates are moving apart. The ridge is formed along lines of the weakest points between the two plates.
What does divergent result in?
It results in sea floor spreading.
Is rainbow a light source?
no it isnt. It is a result of a phenomenon of light
