Describe the formation of a tsunami wave

  1. As a tsunami gets nearer to land it is transformed. The speed at which a tsunami travels is related to the depth of the water. 

  2. When the tsunami is approaching land, the water depth shallows and the tsunami speed slows. 

  3. As it slows its height increases.
