  4. 4. Rock OriginRock Origin • We think that this rock once was magma underneath Mount Tongariro . Then one day in 1896, the volcano erupted and the magma shot up through the pipe and the vents. The magma which is now called lava poured out onto the side of the volcano. We think it came from the eruption. We think that originally the rock was jagged and sharp.
  5. 5. Mount Tongariro has a height of 1,978 meters (6,489 feet). It's first recorded eruption was 260,000 years ago, and is one of the earliest known eruptions in the world. It is quite active, having erupted 70 times since 1839. The last eruption took place in 1977.
  6. 6. • The lava solidified and turned into rock. After that it rolled into a stream or river and was transported down the Waikato River to Anne Street Hamilton.
  7. 7. The rocks change shape and sometimes even colour. There are four different kinds of erosion. Ice, water, wind, gravity.
  8. 8. Type of rockType of rock Our rock that was found in Hamilton by the Waikato River it is igneous because it was once a piece of lava that solidified.
  9. 9. • If we had not taken the rock from the side of the river, we think that the rock would have kept rolling along the river bed. Then it will be pushed along by the current and other rocks until it reaches the ocean floor. It will be eroded down into sediment.
