What exactly is a tsunami?

A tsunami is a series of extremely long waves caused by a large and sudden displacement of the ocean, usually the result of an earthquake below or near the ocean floor. This force creates waves that radiate outward in all directions away from their source, sometimes crossing entire ocean basins.

Why is it called a tsunami?

The word tsunami (pronounced tsoo-nah’-mee) is composed of the Japanese words “tsu” (which means harbor) and “nami” (which means “wave”). 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?

Tsunami is a phenomenon where a series of strong waves that are responsible for the surge in water sometimes reach the heights in many meters. This is a natural disaster that is caused due to the volcano eruption in the ocean beds. Also, a phenomenon like landslides and earthquakes contributes to reasons for a tsunami.

How do tsunami work?

A tsunami occurs because the water mass of the ocean is displaced and, much like throwing a stone into a pond, waves are generated. The displacement in a tsunami creates a wave which is very long – up to 200 km (125 miles). In spite of this speed and power, out at sea the wave is usually less than one metre high.

Where do tsunamis occur?

Pacific Ocean
Tsunamis occur most often in the Pacific Ocean and Indonesia because the Pacific Rim bordering the Ocean has a large number of active submarine earthquake zones. However, tsunamis have also occurred recently in the Mediterranean Sea region and are expected in the Caribbean Sea as well.

What good can a tsunami do?

A tsunami provides habitat for many living things. It also provides food for some, and disperses seeds, plants, and some animals to new locations. A tsunami can cover or uncover treasures. The scar it leaves can be used as an event marker in widely separated locations. This helps scientists refine timelines.

What is a tsunami and how it is generated?

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 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.

How much damage can a tsunami do?

A Tsunami causes a lot of damage including loss of life escaping a Tsunami is almost impossible, hundreds and thousands of people are killed by tsunamis they have been responsible for the loss of more than 430,000 lives. The damage is caused by the wave itself as…
