Largest Ocean - Pacific Ocean

The pacific ocean is the largest ocean in the world.  It covers nearly 1/3 of the earth's surface.  It is also the deepest ocean on the earth.  The pacific ocean lies between Asia and Australia on the west and North and South America on the East.  Pacific ocean is rich in natural resources and marine life. 
The Pacific's deepest parts are the ocean trenches.  These trenches are long,narrow, steep and very deep holes at the bottom of the ocean.  The deepest trench is the Mariana trench.  The deepth of this trench is more than the hight of Mt.Everest.
There are many islands in the Pacific ocean like Taiwan, Indonesia, Japan and New Zealand.  Other islands have risen from the floor of the ocean.  Some of them were from the volcanoes.  The islands were built over thousands of years by the lava that comes out of the volcanoes.  The Hawaiian islands are from volcanoes.
