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.
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
• 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.
The rocks change shape and sometimes
even colour. There are four different kinds
of erosion. Ice, water, wind, gravity.
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.
• 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
