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.
Megabyte unit symbol is MB, Kilobyte unit symbol is KB. Megabyte is greater than Kilobyte. MB has the prefix Mega. KB has the prefix Kilo. Megabyte is 1000 times bigger than Kilobyte. Megabyte (MB) is a unit of transferred or stored digital information, which is extensively used in information and computer technology. In SI, one megabyte is equal to 1,000,000 bytes. At the same time, practically 1 megabyte is used as 220 B, which means 1,048,576 bytes.
