You are vacationing in iceland and exploring one of its famous volcanoes, eyjafjallajokul, which erupted in april 2010. while sightseeing, you find some rocks near the base of the volcano. what type of rock would these most likely be?

igneous

metamorphic

sedimentary

lavaneous

Igneous

Explanation:

A volcano region is where aesthenospheric rocks are released to the surface of the earth.  This aesthenosphere rocks are usually semi liquid and highly viscous . The volcanic eruption releases magma originating from the aesthenosphere to the surrounding.  When this magma creeps or erupt to the surface of the earth , it is known as lava.

Due to the low temperature and pressure the surface of the earth possess, the Lava solidifies to form extrusive igneous rocks.

Igneous rocks can be formed below the earth surface or on the earth surface . The location where this rocks forms determines the kind of igneous rock formed.

Generally, Igneous rocks are formed from molten magma. If the molten magma solidifies on the surface of the earth like the case of the famous volcanoes, Eyjafjallajokul the rocks formed are known as Extrusive igneous rocks.  

Rocks most likely found at the base of the volcano will be an igneous rock.
