Transcripts - KINDS OF ROCKS

  • 1. ROCKS AND WEATHERING Made by: Momina Rizvi ,Sandesh Kumar, Muskan Kataria VIII-H
  • 2. Types of Rocks
  • 3. Igneous Rocks • Igneous rocks are crystalline solids which form directly from the cooling of magma. This is an exothermic process (it loses heat) and involves a phase from the liquid to the solid state.
  • 4. Sedimentary Rocks In most places on the surface, the igneous rocks which make up the majority of the crust are covered by a thin veneer of loose sediment, and the rock which is made as layers of this debris get compacted and cemented together.
  • 5. Metamorphic rocks Metamorphic Rocks The metamorphic get their name from "meta" (change) and "morph" (form). Any rock can become a metamorphic rock. All that is required is for the rock to be moved into an environment in which the minerals which make up the rock become unstable and out of equilibrium with the new environmental conditions.
