Question

how do you identify the cause of tsunami as an internal or external force of the earth? justify your statement​

Answer 1

Explanation:

Scientists can monitor the arrival of earthquake waves at different points on the Earth, allowing them to build a model of the Earth's interior and deduce how earthquakes are caused. Tsunamis are rapidly moving, destructive tidal waves that are most commonly caused by underwater earthquakes.

Answer 2

The cause of Tsunami is an internal force of the Earth.  

Explanation:  

• Earthquakes often trigger the occurrence of Tsunami.
• When these earthquakes occur deep down the earth’s surface it leads to movement of the tectonic plates that impact the plates under the sea level also, and this creates a massive force that influences the water of the sea in creating massive waves.  
• These massive waves crash into the land and create what is known as a tsunami.
• As these are triggered by the earthquakes that are considered as an internal force of Earth, tsunamis are also the result of internal force.
