Spreading-center volcanism is associated with basalt. It is a type of intrusive igneous rock that sometimes exhibits a columnar structure.

What types of volcanoes are formed at spreading centers?
Volcanoes at spreading centers is referred to as spreading center volcanism. This usually takes place on mid-oceanic ridges where the plates diverge.
Do earthquakes and volcanism affect each others plates?
yes they do if they occur in the same area.
Where does sea floor spreading occur?
Sea floor spreading occurs at mid-ocean ridges.
Is there evidence of volcanic activity on Saturn and Uranus?
Volcanism occurs on planets with a liquid metal layer beneath a solid rock layer. Saturn and Uranus are gas giants and have neither, being completely composed of gas. Therefore, no volcanism can occur on those planets or Neptune or Jupiter for that matter. They can occur on the moons, however, under the right circumstances. Io, a moon of Jupiter, experiences the most volcanism of any celestial body in the solar system.
Why does continental drift occur?
because of sea-floor spreading

Characterized by basaltic volcanism and seafloor spreading?
divergent
What is necessary for volcanism to occur on a planet?
Internal heat.
Is it true or false volcanism occurs on planets whose interiors have completely cooled?
Volcanism can only occur on planets with a liquid mantle.
How does a volcano occur in the middle of a continental or oceanic plate?
Intraplate volcanism.
At what boundary does sea-floor spreading occur?
Consider. In sea-floor spreading, the plates are spreading apart; in other words diverging. So sea-floor spreading occurs at a divergent boundary,
Which type of plate boundary does rift volcanism occur?
Divergent plate boundaries n_n ;*
Do earthquakes and volcanism affect each others plates?
yes they do if they occur in the same area.
What is a spreading center on the ocean floor?
sea floor-spreading..;)
Where does most volcanism on planet Earth occur?
I'm not 100% sure, but I believe it is probably Hawaii.
Where would the youngest crust on the Earth be found?
At oceanic spreading centres where new oceanic crust is being formed. Also at areas of recent volcanism.
Where does sea floor spreading occur?
Sea floor spreading occurs at mid-ocean ridges.
