Society of New Zealand: Ask-a-Geologist |
Have
you ever asked yourself a question about volcanoes, earthquakes,
landslides, glaciers, fossils, or rivers?
Why not travel back in time and discover the Earth beneath your
feet. Your planet is your home, a very ancient one - do you understand
its structure, heating, and plumbing, and why it creaks and groans
at times?
If you have a question about the Earth, why not ask a Geologist
for an answer! |

New
Zealand's position on the boundary of the Australian and Pacific
plates is the reason for the large number of earthquakes we witness.
Underneath New Zealand these two huge plates are grinding together
in three distinct ways. |

New
Zealand is located on the boundary between two of the Earth’s
great tectonic plates – the Australian and the Pacific. |

| Plate
Tectonics |
The
story of plate tectonics is a fascinating story of continents
drifting majestically from place to place breaking apart, colliding,
and grinding against each other; of terrestrial mountain ranges
rising up like rumples in rugs being pushed together; of oceans
opening and closing and undersea mountain chains girdling the
planet like seams on a baseball; of violent earthquakes and fiery
volcanoes. Plate Tectonics describes the intricate design of a
complex, living planet in a state of dynamic flux. |

Plate
Tectonics, the Cause of Earthquakes
The plates consist of an outer layer of the Earth, the lithosphere,
which is cool enough to behave as a more or less rigid shell.
Occasionally the hot asthenosphere of the Earth finds a weak place
in the lithosphere to rise buoyantly as a plume, or hotspot. |
