As the plates continue to press against one another, the ocean plate gradually sinks beneath the continental crust and re-enters the mantle. According to Live Science, the deepest known ocean trench is the Mariana Trench, located in the Pacific Ocean. It is approximately 1,500 miles long. The deepest portion of the Mariana Trench is the Challenger Deep, a narrow portion at the southern end, which is roughly 36,000 feet deep. The water temperature in this area is slightly above freezing.The world's ocean trenches remain largely unexplored due to the immense pressures at such depths.
These are computer measurements of the size of a folder, file, hard drive, etc. 1  A bit is a binary digit. 2  A byte is 8 bits. 3  A kilobyte (kB) is 1,000 bytes.  A megabyte (MB) is 1,000,000 bytes.
There are 1000kB in 1MB. The was SI unit prefixes are interpreted, 1 megabyte should be equal to 1000 kilobytes. A kilobyte is 1000 bytes, while a megabyte is 1000^2 bytes. The same as a kilometre being 1000 metres, and a megametre (which we don...
