        Eruption
        
        When a volcano erupts, lava is spewed all over the place.
        
        Lava will not last forever
        
        Dries up
        
        Hardens

      - Magma
        
        Hardens
        
        Underground
        
        Igneous rock can be formed under tha ground. This is when the molten rocks or magma hardens and cools under the ground
        
        Goes to the surface from eruptions
        
        When a volcano erupts, rocks and lava will be spewed up
  - - - Pressure
        
        Presseure builds up
        
        Forces rocks together
        
        Making a new rock
      - Heat
        
        Decomposes rocks
        
        Mushes together many different parts of tiny rocks to form new rocks
  - - - Millions of years
        
        Sediments must merge
        
        Natural formation
        
        Slow
        
        When it is formed naturally, it takes a very ling time
        
        Cluster together
        
        The first step of making a sedimentary rock is form there to be a cluster of sediments. It won’t be tightly pack, just being together
      - Slow compressiont
    - - Sediments
        
        Tiny pieces of rock
        
        Formed from natural breakdown
        
        Weathering
        
        Wind
        
        water
        
        Weathering is when wind or water is being rubbed and is shaving of portion of rocks or other natural earthly objects which slowly decreases its size
        
        Freeze-thaw cycle
        
        Water seeps into cracks in the rock
        
        Freezes over time

        Depending on where the rock is, water can enter the stone through various different ways.
