Which Is The Deepest Ocean?

The oceans remain a mystery to us still in many ways. We do not know how old the oceans are. It appears that oceans did not exist in the initial stages of the earth’s growth. We are exploring the bottoms of the oceans in order to know more about them. Soft, oozy mud covers the ocean floor to a depth of about 3650 meters. It is composed of limy skeletons of sea animals. The floor of the deep, dark regions of the sea, with a water depth of more than 6 kilometers is covered with fine, rusty ooze called “red clay”. It consists of animal skeletons, tiny plants, and volcanic ash.

Now, with sound waves, we measure the depth of the oceans. These waves are reflected back from the bottom. The time is taken to complete the sound cycle and further dividing this time half helps to measure the depth. It gives a reasonably good idea about the depth of various oceans. We also know the deepest point in each ocean. The Pacific Ocean has the deepest point 4284 meters deep. Next in average depth is the Indian ocean with an average depth of 3966 meters. The Atlantic is further down with a depth of 393 meters on average. The Baltic Sea is at the extreme with the least depth and is only 55 meters.

The deepest, single point near Guam in the pacific is 10787 meters deep. The next is in the Atlantic off Puerto Rico and measures 25 meters. The Hudson Bay is larger than many seas and its deepest point is only 183 meters.
