basalt and scoria
Surtsey Island is made up of Scoria rock in the igneous rock.
Igneous rocks form when lava or magma cools.But when cooling there are air bubbles that are trapped in the lava.Prime examples of this event are found in pumice and scoria
None of those. Scoria, Pumice and Granite are igneous rocks. Sandstone is sedimentary.
Quartz is one of the most abundant silicate minerals found in igneous rock.

Most igneous rocks have a relatively homogenous mix of minerals which are interlocked.
None of those. Scoria, Pumice and Granite are igneous rocks. Sandstone is sedimentary.
Olivine and Pyroxene
Extrusive igneous rocks, like basalt, pumice, scoria, obsidian, and rhyolite.
Scoria and pumice are vesicular igneous rocks.
These are all formed by volcanic activity. Igneous
they are found in approximetily 90 %in the earth crust
Neither, Igneous rock is either intrusive or extrusive. Thats what intrusive and extrusive is... A igneous rock.
