How are tsunamis formed?
geniusboy [140]

Answer: Most waves form due to winds or tides, but tsunamis have a different cause altogether. A tsunami is most often formed by an earthquake, but it can also be formed by an underwater landslide, volcano eruption or even meteorite.

The process is fairly complex, so let’s start digging into it.

What are tsunamis and how they form

Most waves form due to winds or tides, but tsunamis have a different cause altogether. A tsunami is most often formed by an earthquake, but it can also be formed by an underwater landslide, volcano eruption or even meteorite.

The process is fairly complex, so let’s start digging into it.

What is a tsunami

“Tsunami” is a Japanese word meaning “harbor wave,” but that doesn’t say much about their nature, and tsunamis are not nearly restricted to harbors. A more accurate term would be “seismic sea waves,” and it would describe them more accurately. However, tsunami has stuck and it’s what everyone uses today. People sometimes refer to them as “tidal waves,” but that term is technically incorrect and should be avoided in this context.

Tsunamis are indeed waves, but unlike wind waves, they have a much larger wavelength. Think a bit about waves — in the context of physics, not in the context of sea waves. A defining characteristic of every wave is its wavelength. Wind waves have short wavelengths which can be clearly seen on any shoreline. They come in every few seconds, with a few meters in between — sometimes, even less. But a tsunami has a huge wavelength, oftentimes longer than a hundred kilometers and this is why they are so dangerous (more on that a bit later). Tsunamis are almost always not singular waves, but come in as train waves.

HOW TSUNAMIS FORM BELOW.

How tsunamis form – earthquakes

The vast majority of tsunamis form due to earthquakes — specifically tectonic tsunamis. As an earthquake happens, the ground beneath the water is moved up and/or down abruptly and as this movement happens, a mass of water is displaced and starts moving in all directions. This marks the start of a tsunami.

The displaced water starts to move as a wave. At this point, it has a very low amplitude as it is located in deep water (earthquakes on the coastline rarely cause tsunamis). Tsunamis in open water are usually shorter than 0.3 meters (12 inches).

Hope this helps!!! Good luck!!! ;)

What evidence is there to support the big bang theory
saveliy_v [14]

1. Galaxies seem to be moving away from us which can support Big Bang Theory.

2. The abundance of Helium and Hydrodgen also support the Big Bang theory!


Personlly I do not believe in the big bang theory but if you need more reasons please comment! :-)

Question 8 of 15 How do trade barriers affect the African economy today? O A. They allow Africa to sell goods at a higher profit
-BARSIC- [3]

Answer:

D. They force Africa to lower the prices on its goods.​

Explanation:

Trade barriers refers to the restrictions on the international trade and commerce that is induced by the government of a country. Trade barriers have a bad effect on the economy of a country. It is detrimental as considered by economist.

Countries like that of Africa who imposed a trade barrier on the international trade suffers a lot on economic efficiency of the country. These countries depends on the exports for funding  their economy. Trade barriers in Africa forced the businesses to sell their goods at a lower price that affects the economy greatly.

What is sheerwood? And why is it important.
boyakko [2]

Local shear failure occurs when the shear stresses parallel to the grain, i.e. shear stresses acting in the longitudinal-tangential (LT) or longitudinal-radial (LR) planes, exceed the shear strength of the beam. The shear strength of a wood member is difficult to quantify.
