Classification of Rocks

• Igneous rocks


  Form when magma (molten rock) cools and crystallizes, either at volcanoes on the surface of the Earth or while the melted rock is still inside the crust
• Extrusive rocks


  Come from the solidification and cooling of lava
• Intrusive rocks


  Come from the cooling and solidification of magma
• Metamorphic rocks


  One of the three main types of rock found on Earth's surface, alongside igneous and sedimentary rocks
• Foliated Metamorphic Rocks


  • Exhibit a layered or banded texture
• Non-foliated Metamorphic Rocks


  • Lack the layered texture
• Sedimentary Rocks

  • is formed through a series of processes: erosion, deposition, compaction, and cementation of mineral or organic particles on the floor of oceans and other bodies of water at the Earth's surface.
