It depends on the natural disaster, for example earthquakes occur when
the Earth's plates shift or jam above/underneath each other. If an
earthquake did occur, there would more than likely be tsunami after it
(especially if this earthquake occurred in the ocean). A tornado is
caused by hot air and cold air mixing together. Hurricanes are formed by
tropical storms. Flooding happens when there is too much rain/water in a
river or other water source. ....
