The oceanic crust is mainly composed of basalt and gabbro.These two rock types are made up of mainly of plagioclase feldspar and pyroxenes, with smaller amounts of olivine, micas and amphiboles.
If able, get your hands on some real rocks for students to touch and observe. You can purchase simple rocks and minerals kits if your school doesnt already have some. If this isnt an option, then pictures of real rocks not clip art are best.. As an introductory activity, before we go over how rocks are classified, I like to let students work in small groups and decide how they might sort them.

Igneous rocks are fashioned deep internal Earths crust intrusive rocks or on the floor extrusive rocks. As molten rock called magma below the surface cools, the liquid cloth starts to solidify into minerals of differing sizes and compositions.
Since rocks are aggregates of mineral grains or crystals, their properties are determined in large part by the properties of their various constituent minerals. In a rock these general properties are determined by averaging the relative properties and sometimes orientations of the various grains or crystals.

Poor management of most of the tailings dams resulted in the escape of seepage, adversely affecting soils and water quality. Some tailings dams have been partially or completely reclaimed leaving contaminated footprints.
