New Zealand earthquake moves it closer to Australia

An earthquake in New Zealand last week has moved it 30cm closer to Australia!

This may sound like nothing, but over millions of years these movements add up.

Believe it or not, the continents have been moving round the world since the planet first formed billions of years ago. This process is called plate tectonics and involves the surface of the Earth being destroyed and reborn. The sections of the surface are called plates and move against, into or apart from each other at their margins. These movements often cause earthquakes, as happened in New Zealand last week.
