The ocean is deep and dark, and much of the ocean floor is covered in sediment. Sediment is made up of small particles of rock and other materials that settle to the bottom of the ocean. This sediment can make the ocean floor difficult to see.
Earthquakes often generate tsunamis. See the related link below:
No. At the the time there was no tsunami warning center in the Indian Ocean. They received no warning. The first indication anyone in Indonesia got was the ocean receding before the tsunami struck, but most people did not know that this was a sign of a tsunami.
The current accepted theory is that the ocean pates are subducted (dive) down toward the earth's interior at the ocean trenches. A major problem with this is that there are not nearly enough trenches to take all the ocean plates. So it has been proposed that the trenches are actually a very deep, wide crack in the ocean floor filled with water and sediment and that molten rock from far below flows toward this now lighter region but forces up mountains over a batholith (a huge mass of molten magma) before it reaches the trench. For further discussion of this see http://charles_w.tripod.com/trenches.html
Tsunamis are very different from ordinary waves on the ocean surface, even very large surface waves. When earthquakes on the ocean floor cause massive and extremely rapid upward or downward shifts of the ocean floor itself, this results in a shift of the entire water column above it. It is the movement of the entire water column from ocean floor to surface that makes a wave a tsunami. You can see that they contain a huge amount of the energy released by the earthquake. Surface waves can affect water going down for several meters, but even in the heaviest seas you could find a water depth where there is little or no movement caused by the waves above. a giant stock wave
Sonar. we send sound waves to the ocean floor and see how long it takes them to bounce and come back. Once we have how long it took and how fast the sound waves traveled we can find the distance
The Continental Shelf ; see related link below .
There is grass(or seaweed or something) on the ocean floor
It blends in with the ocean floor. So enemies can not see the flounder.
The ocean floor is irregular as to the land we can see. It has mountains and ridges and plains and valleys and volcanoes. It even has underwater earthquakes, and just about every other land feature you could name.
Yes, in many places it is. But like the surface of the earth that you can see, the ocean floor has many different topographies. The ocean floor has mountains, volcanoes, deep valleys, and reefs. There vast areas of vegetation and areas that are devoid of vegetation, often due to how deep they are and how much sunlight penetrates. There are also arctic regions of ocean floor as well as tropical regions. The ocean floor is really as varied as the continents above the water.
Nothing much. The ocean floor spreading is in the Atlantic ocean caused by the mid oceanic ridge which is the largest and longest mountain range in the world. It is huge and if you google ocean floor maps you will see a thing that goes all over the oceans floors. The volcanos erupt as the plates shift away from each other.
The ocean is deep and dark, and much of the ocean floor is covered in sediment. Sediment is made up of small particles of rock and other materials that settle to the bottom of the ocean. This sediment can make the ocean floor difficult to see.
Its coloring helps it blend into the ocean floor so predators cannot see it.
To clearly see the ocean floor in Google Earth first turn off the Water Surface layer from the View menu, which shows animating wave for effect.Next expand the Ocean layer in the Layer panel in the Sidebar, which includes ocean and maritime related content (e.g. Explore the Ocean, National Geographic, Shipwrecks, etc.).You also want to check '3D Buildings' layer since there are some 3D models at the bottom of the ocean like the HMS Titanic.Navigating the ocean floors with mouse controls sometimes gets tricky. The keyboard short-cuts work well for "walking" the ocean floor (see links to key stroke controls in related links below).
no
This is known as an accretionary wedge or prism. Please see the related link.
