near a dormant volcano

Explanation:

Igneous rocks can be classified as extrusive and intrusive igneous rock. The disparity in the classification of igneous rocks is base on it formative environment.

Generally, igneous rocks are formed from molten magma . This molten magma are usually semi liquid. After exposure to conducive pressure and temperature they tend to solidified forming igneous rocks.  When this molten magma solidify in the interior of the earth surface it form intrusive igneous rocks  . The solidification of this magma on the earth surface forms extrusive igneous rocks.

Volcano prone area are region where this magma are introduce to the earth surface . The magma may erupt or introduce through cracks and fissures on the earth surface.This magma solidify to form extrusive igneous rocks.

A dormant volcano is a volcano that has long erupted but is expected to erupt in the future.  A dormant volcano region is where one is likely to find extrusive igneous rocks because it has experience eruption of magma to the earth surface that later solidified to form these rocks.

heat from the core of the earth causes convection currents to occur in the mantle. these currents slowly move the crust around.
