This document provides information about Lake Taupo in New Zealand, as well as definitions and explanations of magma, lava, and how volcanoes work. Lake Taupo is one of the largest volcanic lakes in New Zealand, covering 616 square kilometers. Magma is molten or semi-molten rock found below the Earth's surface. Lava is molten rock expelled during a volcanic eruption that can flow great distances before solidifying. Volcanoes are caused by movement of tectonic plates underground, which allows hot magma to escape and erupt on the surface.

3. About Lake Taupo?
Lake Taupo is one of the biggest volcanic eruptions in
New Zealand.
Lake Taupo is a lake situated in the North Island
of New Zealand.
It's surface area of 616 square kilometres
(238 sq mi)

4. What is magma?
Magma is a mixture of molten or semi molten
rock, volatiles and solids that is found beneath
the surface of the Earth, and is expected to
exist on other planets. Magma may also
contain crystals and dissolved gas and
sometimes also gas bubbles

5. What is lava?
Lava refers both to molten rock expelled by a volcano during an
eruption and the resulting rock after cooling. This molten rock is
formed in the interior of some planets, including Earth, and some of
their satellites. When first erupted from a volcanic vent, lava is a
liquid at temperatures from 700 °C to 1,200 °C (1,300 °F to
2,200 °F). Up to 100,000 times as viscous as water, lava can flow
great distances before cooling and solidifying because of its shear
thinning properties.

6. How does a volcanoe
work?
Beneath the Earth's surface there are rock plates that occasionally move causing
earthquakes. Beneath those plates there is hot magma. When the magma is able
to escape from the plates, it causes a volcanic eruption on the Earth's surface.
