Public Meeting Tuesday 25th September 2018

~  Our next meeting is this Tuesday 25th September

Program:

Planet Earth’s Techtonic Plate Movement

Plate tectonics is a scientific theory describing the large-scale motion of seven large plates and the movements of a larger number of smaller plates of the Earth’s lithosphere, since tectonic processes began on Earth between 3 and 3.5 billion years ago.  (Wikipedia)

Major Plates

The program suggests the possibility of similar structures on some exoplanets (planets outside our solar system). New Zealand is presented as an example of our planet’s dynamic crust history.

 

New Zealand is on shaky ground

The Alpine Fault is the dominant structure defining the Australian-Pacific plate boundary in the South Island of New Zealand. It runs as a single structure for over 500 km. It forms the sharp line separating the snow-covered Southern Alps in the east from the low coastal plain bordering the Tasman Sea in the west.
