= Why and How earthquakes happen? = ===The reason why tectonic plates move is because the plates float on the **mantle**. The mantle is an area between the **core** and the **crust**. That mantle is basically filled with molten rock. It is kept in a liquid because of the energy given off by the center of the core of the Earth. Scientists have also discovered that the pressure increases as you move towards the center of the planet. The core of the Earth has extreme temperatures and pressures that keep the iron and metals liquid and flowing.===

Earthquakes are triggered when tectonic plates shift, rub or move up against each other. This also causes volcanoes, landslides and tsunamis.
===Australia is fortunate that we do not have big earthquakes but we still have minor earthquakes that we can not feel. The reason we do not have big earthquakes is because we are in the middle of a tectonic plate. We don't have those plate boundary forces putting stress on the rocks within the continent. Although Australia is not on the edge of a plate, the continent experiences minor earthquakes because the Indo-Australian plate is being pushed north and is colliding with the Euro-asian tectonic plate.===
