Why did the tsunami get bigger as it approached land?
When the waves come closer to the land they rub against the sea floor, and friction causes the waves to slow down and build up from behind creating huge piles of water to crash on the land A tsunami spreads out from an earthquake's epicenter and speeds across the ocean. In the open ocean, the height of the wave is low. As a tsunami approaches shallow water, the wave grows into a mountain of water.
What direction does a tsunami move in?
The tsunami wave moves through the ocean at about 400 mph. When it hits the shore it rises up and floods/smashes.
How does the depth of sea affect a tsunami?
The wave generated by a tsunami is really a large swell. Swells continue along until they meet the resistance of shallowing water. When the depth of the water can no longer handle the volume of water, the wave will rise up on top of the sand in shallower water and break. If the land form creates a gentle slope then the tsunami will appear as a very strong tidal flow. If the shore is steep then the swell will rise up and break against the beach. Most damage is not done by a large crashing wave, but by the sheer volume of water that is flowing onto the land and carrying debris along with it.
Is an earthquake always followed by a tsunami?
No, not all earthquakes are followed by tsunamis. Tsunamis are typically caused by underwater earthquakes or landslides, but not all earthquakes generate tsunamis. The likelihood of a tsunami depends on the magnitude and location of the earthquake.
How does the tsunami form as it approaches land?
A tsunami is formed when an earthquake happens from tectonic plates are shifting underwater. These ripples happen and travel to land. If you imagine a slinkey when you push on one side of it, it moves because sections hit eachother and cause the attached sections to move in the same direction. As the tsunami comes up to land, it's area decreases because of the rising level of the sea floor, pushing water above the sealevel, causing a giant wave.
How a tsunami wave forms in the deep part of the ocean and what happens as it approaches land?
I think their is an earthquake in the ocean and it roles up into a huge wave and when it approches land it is as biggest as it can get and boom it hits the land

Does marine life get stranded on land after a tsunami?
It gets washed up shore.

What was the speed of the tsunami after the earthquake in Japan on March 11 2011?
Britain's National Oceanography Centre said "the tsunami quickly roared through the Pacific Ocean at comparable speeds to a jumbo jet flying in the sky".The speed of tsunami waves depends on the depth of the sea where the waves occurs, where the speed can reach hundreds of kilometers per hour if the tsunami forms in deep water. When it hits land it is "almost like a freight train that smashes everything in its path," said a professor of engineering at the University of Ottawa, "usually in a sequence of two or three waves".The tsunami wave height can reach a few centimeters to several meters, but when it reaches shore the wave height can reach tens of meters due to a buildup of the water. When the tsunami reaches the coast of the mainland it could travel over land with a range of several hundred meters up to a few kilometers. In the case of Japan's recent tsunami it reached up to 10 km or (6 mi) inland.Another Answer:500 MPH is the commonly accepted speed of the energy wave in a tsunami in the open ocean. In this state, it typically only has an amplitude of a couple of feet. Most boats in the ocean will not even notice a tsunami as it goes past them. As it approachs land, however, it slows down and gains amplitude. This change depends on the topography of the ocean floor, but a typical approach speed is about 50 MPH with an amplitude closer to 30 to 60 feet, depending on the energy.

Can a land speed car go up to 2000 mph?
i believe that the current land speed record is around 1260mph and it was set by the australlians
When a wave approaches shallow water the?
When an underwater wave approaches shallow water, the wave is pushed up above normal water level, and then travels toward land above normal water level.
What is a constructive force of nature A volcano B tsunami C hurricane or D erosion?
Volcanoes are constructive, as they build up the land.
