• Igneous Rocks Reading Comprehension

    Igneous Rocks. There are three main types of rocks: sedimentary, igneous, and metamorphic. Each type of rock has its own characteristics and properties, are part of the rock cycle, and can be found all over the world.

  • Granite

    Granites are generally formed as "batholiths" at great depth and when exposed by erosion or other tectonic activity, these rocks occupy huge areas of the Earth''s surface, often as series of domes ( Fig. 4.8) and valleys. The central cores of major mountain ranges consist of intrusive igneous rocks, usually granites.
