Mountains such as Everest have reached the height limit.
The lighter crust, or mantle, consisting of lighter elements floats on top of heavier elements in the core. The core being liquid magma is in motion. This motion of the magma causes tectonic plates of the crust to move, separate in some area and collide in other areas .
Being slammed together the African and Indian plates are thrust up highrer and higher
Once the mass of a mountain becomes so great it can no longer be supported by the magma. then that mountain has reached the limit in height.
Undersea volcanic islands are partially bouyed up by the density of water, These undersea mountains , are often at area where the crust is thin and magma under pressure is escaping .
The crust is also moving over hot spots so islands often form in chains as the crust moves over a hot spot.

Look up plate tectonics on the Internet, or better yet take a Geology course. The shifting of the earth's crust, which is made up of a series of plates, causes mountain ranges, volcanoes, earthquakes, etc. If you choose to look this up, you will most likely read of Pangea, the "original" continent which was the product of the Americas, Antarctica, Europe, Asia, and Australia all connected. due to the shifting of the plates, the continents broke away from each other and went their separate ways. look at a map and you will see in the Americas there are several longitudinal mountain ranges running from north to south America, all within the same region. this is the same in Europe and Asia. these ranges were formed when these plates crashed together. the oceans became deep as the plates diverged together, with one going underneath the other. this is also the cause of underwater volcanoes.

If you put them together, you get the highest mountain on Earth: Hawaii (the main island). It is the higher than Everest if you measure from the base under the ocean to the peak above the ocean.
If you want the current theory of why oceans are deep and mountains so high, look up plate tectonics.

In comparison with the size of the planet, oceans are not deep and mountains are not high. If you laid out the distance from the bottom of the deepest trench, the Marianas trench to the top of Mt Everest horizontally, it is less than 20km. You could walk it in two hours and a good marathon runner could run it in one.
I know Americans like to claim Mauna Kea as the highest mountain but it isn't. The height of mountains is measured from sea level which makes Everest the biggie.

this is called Geology it is just the way it is do not dwell on it for.
In the future you may walk around the highest peak ..or you may drive on the ocean bed and loot the old pirate ships ...the way global warming is going just be ready for the unexpected.

It is that way so someone could write a song about it. Uh--I think Dick and Dee Dee made the record in the 60s..

becoz oceans are not high & mountains are not deep...
rephrase your question..it has both philosophical & geological overtones..now how am i supposed to know wat asnwer you want?
