Pressure builds up from under the Earth in the moho or asthenosphere from molten lava and the Earth's crust is pushed and eventually cracks and lava seeps out through the crack therefore forming a volcano.

Are hot spots stationary?
Yes; hot spots are huge columns of hot mantle material rising from a great depth. New volcanoes form and old volcanoes become extinct as plates move over the hot spots.
Do shield volcanoes form at hot spots?
Yes I am pretty sure.
How volcanoes form in Hawaii?
volcanoes in Hawaii are formed by hot spots hot spots are areas of constant volcano activity. They are derived from unusually hot areas in the mantle. The overlapping mantle forms plumes of magma that rise and form volcanoes. source: http://visearth.ucsd.edu/VisE_Int/platetectonics/hot_spot.html
What type of volcanoes form on a hot spot?
Cinder Cones Mainly Form At Hot Spots off the coast of Africa, Eurasian Plate boundary, etc.
The hawaiian islands are a chain of volcanoes that form over?
that were formed over hot spots
Are shield volcanoes hot spots?
Shield volcanoes are not hot spots but they are associated with them. However, such volcanoes can also form at rift zones.
What do hot spots form?
flood basalts and volcanoes
Where do shield volcanoes form?
at hot spots(a place where volcanoes are very active)
Volcanoes that form far from plate boundaries form as the result as?
Hot spots!
Are hot spots stationary?
Yes; hot spots are huge columns of hot mantle material rising from a great depth. New volcanoes form and old volcanoes become extinct as plates move over the hot spots.
Other than volcanoes what can hot spots form?
flood basalts
Do shield volcanoes form at hot spots?

Why do they have volcanoes?
Volcanoes form from either techtonic plates crashing together or from hot spots under the earth
What kind of boundary do Shield volcanoes form?
hot spots and convergent boundaries
Do solitary volcanoes form as a result of hot spots?
the hotspots of volcanoes are when they are near tectonic plates when diverting or coliding
