Comment on this resource
This interactive lesson on igneous rocks begins with a comparison of intrusive and extrusive igneous rocks with diagrams to show their origin. This leads to a discussion of intrusive rock formations including dikes, sills, laccoliths and batholiths and a block diagram to show their location. Basaltic rocks are described to include basalt, pumice, and gabbro and are contrasted with granitic rhyolite and obsidian.
