    • IGNEOUS ROCKS By Sophia and Danny
    • HOW IGNEOUS ROCKS ARE FORMED
      • Igneous rocks are rocks formed by the cooling, hardening, and the freezing of lava or magma
      • Igneous rocks may or may
      • not crystallize while cooling
      • Most of the 700 igneous rocks
      • are formed under the Earth’s crust
    • THE ROCK TYPES AND THEIR DIFFERENCES
      • Igneous
      • Sedimentary
      • Metamorphic
      • The difference between igneous and metamorphic is that the metamorphic rocks are formed under pressure and igneous rocks are just cooled off lava/magma.
      • The difference between igneous and sedimentary rocks are that sedimentary rocks are made of different rocks, animal parts, and plants mushed together to make one rock.
      • Intrusive rocks:
      • Solidified inside the Earth’s surface
      • As the active volcano turns into a extinct volcano, the lava /magma inside hardens and becomes a Intrusive Igneous rock
      INTRUSIVE AND EXTRUSIVE ROCKS
      • Extrusive rocks:
      • Solidified above the Earth’s surface.
      • First a volcano erupts or magma/lava oozes out the volcano. Then the magma/lava cools or hardens to form a extrusive igneous rock
      • Extrusive rocks:
      • Basalt
      • Obsidian
      • Pumice
      • Rhyolite
      • Scoria
      TYPES OF INTRUSIVE AND EXTRUSIVE IGNEOUS ROCKS
      • Intrusive rocks:
      • Diorite
      • Gabbro
      • Pegmatite
      • Granite
    • THE ROCK CYCLE
      • This is the rock cycle:
    • WE HOPE YOU WERE LISTENING! THAT’S BECAUSE THERE IS GOING TO BE A QUIZ!
    • QUIZ!
      • What rock is this rock?
      • Is a Gabbro an intrusive or an extrusive rock?
      • What’s the difference between an intrusive and a extrusive rock?
      • Who are the authors of this PowerPoint?
    • A JOKE
      • Q=What music does rocks like best?
      • A=rock & roll!
    • WORDS YOU MAY NOT KNOW/INDEX
      • Crystallize- A form of a rock slowly or quickly turned into a crystal/rock
      • lava/magma-a liquid that is formed inside a volcano, and when cooled off it’s turned into a igneous rock
      • Sophia-wisdom
      • Danny-Clear water of the East Sea
    • ANY QUESTIONS? Ask a question Or we’ll tickle this cute kitty!
    • APPLAUSE FOR US! (Please)
