In this free science game, players locate an earthquake's epicenter! Can you ride the seismic waves? Or will triangulation get the better of you?
Earthquake, any sudden shaking of the ground caused by the passage of seismic waves through Earth’s rocks. Earthquakes occur most often along geologic faults, narrow zones where rock masses move in relation to one another. Learn more about the causes and effects of earthquakes in this article.
New Zealand's stunning landscape was formed by geological processes over tens of millions of years — and that same geology is what makes the North Island a centre of volcanic activity.
These fiery peaks have belched up molten rock, hot ash, and gas since Earth formed billions of years ago.
According to the theory of plate tectonics, Earth is an active planet. Its surface is composed of many individual plates that move and interact, constantly changing and reshaping Earth's outer layer. Volcanoes and earthquakes both result from the movement of tectonic plates. In this interactive activity produced for Teachers' Domain with images from NASA, see the relationship between earthquakes and volcanoes and the boundaries of tectonic plates.
