Why did the tsunami get bigger as it approached land?

Answer 1

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.

Answer 2

The reason for this is that as you get closer and closer to shore, there is less depth an the water is more shallow. With a tsunami, the water displaced by the rising ocean floor creates bigger, taller waves. Some tsunamis are only inches high in the middle of the ocean, but can become much larger approaching land.

Answer 4

The Tsunami waves got bigger (or higher) as they approached land because the swells of water rise up as the seafloor gets shallower.
it gets higher when it gets closer to shore and gets ready to crest.

Answer 5

As a tsunami enters shallower waters near the coastline, its speed decreases and the energy within the wave is compressed, causing it to increase in height and intensity. This process is known as wave shoaling and leads to the tsunami appearing bigger as it moves towards land.

Answer 6

They don't. It's just the wave speed/energy is converted to height as the depth of the sea bed lessens.

Answer 7

They grow larger because as they travel across the ocean they pick up more water thus resulting in a larger wave.

Answer 8

The seafloor is shallower and the frequency of the wave increases, thus pushing the water up into the air.

Answer 9

Because they feel like it.
