2. Basaltic (buh SAWL tihk) igneous rocks are dense, dark-colored rocks.
Basaltic lava is fluid and flows freely from volcanoes in Hawaii, such as Kilauea.
Granitic igneous rocks are light-colored rocks of lower density than basaltic rocks.
Granitic magma is thick and stiff and contains lots of silica but lesser amounts of iron and magnesium.
