In "The Deadliest Tsunami in History," the cause of the Indian Ocean tsunami was (1 point)
• an unintended explosion in Japan.
O a tornado off the coast of Sumatra.
• mass animal migrations to the North.
a rupture in the Burma plate.
a rupture in the Burma plate.
The cause of the Indian Ocean tsunami was a rupture in the Burma plate.
To determine the cause of the Indian Ocean tsunami, we can analyze the given options and eliminate the ones that are clearly incorrect.
Option 1: "An unintended explosion in Japan" is not related to the Indian Ocean tsunami. Tsunamis are typically caused by geological events rather than man-made explosions.
Option 2: "A tornado off the coast of Sumatra" is also an inaccurate statement. Tornadoes are not responsible for the formation of tsunamis.
Option 3: "Mass animal migrations to the North" is not relevant to the cause of the Indian Ocean tsunami. Animal migrations do not trigger the formation of tsunamis.
Finally, we are left with option 4: "A rupture in the Burma plate." This option indicates a geological event that could potentially lead to a tsunami. A rupture or seismic activity in the Earth's crust, such as in a tectonic plate, can generate massive undersea movements, causing a tsunami.
Therefore, the correct answer is: a rupture in the Burma plate.
