Question: How is a tsunami different from an ordinary ocean wave quizlet?

How is a tsunami different from an ordinary ocean wave?

Tsunamis occur as a result of the movement of a huge volume of seawater from the seabed to the sea surface, whereas ocean waves are caused by the movement of wind over the sea surface. … As a tsunami comes closer to the coast, its speed and wavelength decrease, but its height increases.

What is the typical period for a tsunami wave quizlet?

the length of time between two successive wave peaks or troughs. Tsunami periods generally range from 5 to 60 minutes. The maximum height of the water onshore.

What is the definition of tsunami wavelength quizlet?

-Tsunami wave has wavelength of 100-200km with deep water heigh of 1m or less. -Travels as fast as 200 m/s (440mi/hour) in open ocean. -As it approaches the shore, it slows, steepens, and rises. What does it mean “The wave keeps coming”?

How is a tsunami similar to a ripple in a pond How does it differ?

37.2- How is a tsunami similar to a ripple in a pond? Tsunami is caused by a large disturbance. … Ripples are triggered by small disturbance.

What is a tsunami How are tsunami generated quizlet?

Most tsunamis are caused by earthquakes generated in a subduction zone, an area where an oceanic plate is being forced down into the mantle by plate tectonic forces. The friction between the subducting plate and the overriding plate is enormous.

What is a characteristic of a tsunami quizlet?

Tsunamis have a very long wavelength (sometimes over 100km) and a low wave height (under 1 metre) in the open ocean, and they travel quickly at speeds of over 700km per hour but, when reaching shallow water bordering land, increase rapidly in height.

What happens to a tsunami wave as it approaches the shore quizlet?

What happens to a wave when it reaches the shore? As the wave comes near the shore, the ocean floor starts to slope upward towards the beach (the slope is called the continental shelf). The ocean floor causes friction on the wave and the wave length gets shorter and the wave hight increases.

What is tsunami in Brainly?

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. 1jaiz4 and 29 more users found this answer helpful. Thanks 18. 3.8.

What is a tsunami quizlet geology?

Tsunami. a wave train or series of waves generated in a body of water by an impulsive disturbance that vertically displaces the water column or by the transfer of momentum to the ocean water.

What is a typical tsunami wavelength?

A very large wind-generated wave might have a wavelength of 200 meters (650 feet), but a typical tsunami has a wavelength of 200 kilometers (120 miles). … Incredibly, tsunamis can travel at 800 kilometers per hour or kph (500 miles per hour or mph) in the open ocean.
