What is tsunami short answer?

A tsunami is a series of waves caused by earthquakes or undersea volcanic eruptions. The tsunami was generated by a large earthquake in the Southern Pacific Ocean. Tsunamis are giant waves caused by earthquakes or volcanic eruptions under the sea.

What is a tsunami for kids?

Tsunami is a Japanese word that means “harbor wave.” It is a large wave caused by movements in Earth’s outer layer, or crust, which move ocean water. For example, an earthquake or a volcano in the ocean could cause a tsunami. Earth’s crust is made up of pieces called tectonic plates.

What is a tsunami Class 7?

A tsunami is a series of huge waves caused by the shifting of large amounts of ocean water. Tsunamis are also caused by volcanic eruptions and underwater landslides.

What is meant tsunami?

The phenomenon we call tsunami is a series of large waves of extremely long wavelength and period usually generated by a violent, impulsive undersea disturbance or activity near the coast or in the ocean. Thus, the Japanese word “tsunami”, meaning “harbor wave” is the correct, official and all-inclusive term.

What is a tsunami Class 10?

A tsunami is a sequence of waves in a body of water caused by a large amount of water being displaced, usually in an ocean or a large lake. When the seafloor suddenly deforms and vertically displaces the overlying water, tsunamis can be produced.

What is a tsunami Class 9?

Answer: The term Tsunami means harbour wave. A wind-generated wave persists for a few seconds, while Tsunami persists for minutes to hours. Tsunamis may be extremely damaging, which is not the wave generated by wind.

What is a tsunami Class 8?

Answer: A tsunami is a very large and powerful wave. It is caused by earthquakes under the sea.

What is a tsunami caused by?

What causes tsunamis? Most tsunamis are caused by earthquakes on converging tectonic plate boundaries. According to the Global Historical Tsunami Database, since 1900, over 80% of likely tsunamis were generated by earthquakes.

What is tsunami class 9 Samacheer Kalvi?

A tsunami is a series of enormous ocean waves caused by earthquakes, underwater landslides, volcanic eruptions or asteroids. Tsunamis can travel 700-800 km per hour, with waves 10-30 meters high. It causes flooding and disrupts transportation, power, communications, and water supply.

What is tsunami and its causes?

Tsunami are waves caused by sudden movement of the ocean surface due to earthquakes, landslides on the sea floor, land slumping into the ocean, large volcanic eruptions or meteorite impact in the ocean.

What is a tsunami Class 6?

Tsunami is a natural phenomenon generated by strong earthquakes, volcanic eruptions, landslides, or simply a comet or a meteor impact in the ocean, and is a sequence of fast-moving waves in the ocean. A tsunami has a wavelength which is very long. Hundreds of kilometres can belong.

What is the main reason of tsunami?

Most tsunami are caused by large earthquakes on the sea floor when slabs of rock move past each other suddenly, causing the overlying water to move. The resulting waves move away from the source of the earthquake event.

What is the most dangerous tsunami?

The tsunami which happened in the Indian Ocean in the year 2004 is the most deadliest tsunami ever recorded in history. This tsunami is considered the deadliest in history because it has affected more or less 10 countries and has resulted to an extremely high mortality rate.

What are the disadvantages of a tsunami?

Crop loss and damage of agriculture are a direct disadvantage of tsunamis. People and animals drown, houses and property are destroyed, crops are lost, freshwater is contaminated with saltwater, and a lot more.

What is a tsunami and how is it produced?

A tsunami is a series of waves in a water body caused by the displacement of a large volume of water, generally in an ocean or a large lake. Earthquakes, volcanic eruptions and other underwater explosions above or below water all have the potential to generate a tsunami. Unlike normal ocean waves, which are generated by wind, or tides, which are generated by the gravitational pull of the Moon and the Sun, a tsunami is generated by the displacement of water. Tsunami waves do not resemble normal u

What was the worst tsunami in history?

The deadliest tsunami recorded in documented history was on 26 December 2004, and is known as the 2004 Indian Ocean Tsunami. It was caused by an earthquake.
