  Diorite
• Which group of rocks was formed through compressing and heating? a. clastic rock b. igneous rock c. sedimentary rock d. metamorphic rock

  Metamorphic rock
• It is a naturally occurring solid aggregate of minerals sometime with nonmineral solid particles.

  Rock
• 3 classifications of Rocks:

  • Igneous rocks
  • Sedimentary rocks
  • Metamorphic rocks
• They are formed through the cooling and solidification of magma or lava.

  Igneous rocks
• Also called "Magmatic rocks".

  Igneous rocks
• It is formed from solidification of magma below the surface.

  Intrusive Igneous rocks
• How do large crystals in Intrusive rocks form?

  Through slow process of crystallization in a magma.
• Examples of Igneous rocks

  • Granite
  • Diorite
  • Gabbro
  • Pegmatite
  • Peridotite
• They are formed through a faster rate of solidification of lava on the surface of Earth.

  Extrusive Igneous rocks
• Why do some Extrusive rocks become glassy?

  Due to less crystallization or vesicular
• Examples of Extrusive rocks

  • Andesite
  • Basalt
  • Dacite
  • Obsidian
  • Pumice
  • Rhyolite
  • Tuff
  • Scoria
• They are formed by the deposition and cementation of mineral or organic particles on the floor of oceans and other bodies of water at the Earth’s surface.

  Sedimentary rocks
• 2 classifications of Igneous rocks:

  • Intrusive
  • Extrusive
• 3 classifications of Sedimentary rocks

  
  

  • Clastic
  • Chemical
  • Organic
• A kind of Sedimentary rock composed of plants and animal's debris.

  Organic rock
• A classification of Sedimentary rocks formed by mechanical weathering debris of rocks.

  Clastic rocks
• A type of Sedimentary rocks that is formed when dissolved materials precipitate from the solution.

  Chemical rocks
• Examples of Organic rocks

  Coal and Fossiliferous Limestone
• Examples of Chemical rocks

  • Rock salt
  • Iron ore
  • Chert
  • Flint
  • Dolomites
• Examples of Clastic rocks:

  • Breccia
  • Sandstone
  • Siltstone
  • Conglomerate
  • Shale
• They form from existing rock types called “parent rock” in the process called metamorphism.

  Metamorphic rocks
• It is a process in the rock cycle where existing rocks are exposed to intense heat and pressure, resulting in the formation of metamorphic rocks.

  Metamorphism
• A classification of rock that is subjected to heat and pressure.

  Metamorphic rock
• 2 classifications of Metamorphic rocks:

  • Foliated rocks
  • Non-foliated rocks
• It is formed through pressure due to compression of rocks that create bands called foliation.

  Foliated rocks
• A metamorphic rock having no foliation or bands.

  Non-foliated rock
• Examples of non-foliated rocks:

  • Hornfels
  • Quartzite
  • Marble
  • Novaculite
