  • 10(e) Characteristics of Igneous Rocks Physical

    FormationCompositionGeologyThe type of igneous rocks that form from magma is a function of three factors: the chemical composition of the magma; temperature of solidification; and the rate of cooling which influences the crystallization process. Magma can vary chemically in its composition. For example, the amount of silica (SiO 2 ) found in magma can vary from 75% to less than 45%. The temperature of cooling determines which types of minerals are found dominating the rock's composition. Rocks that begin their cooling at low temperatur

  • Reading: Characteristics of Igneous Rocks Geology

    Reading: Characteristics of Igneous Rocks. Magma is molten rock inside the earth. It is the source of all igneous rocks, coming from under the Earth under the pressure from surrounding rocks and because molten rocks have lesser density. Because the earth was largely molten at its origin, magma may be considered the beginning of the rock cycle.

  • Igneous Rocks National Geographic Society
