Ocean trenches are depressions that are created on the ocean floor. These ocean trenches are normally very narrow, but they can be really deep. Some of the ocean trenches are really deep, and it would take a lot of time for the humans to explore such sites inside the ocean floor. Hence, you will require a lot of technical assistance and a team of experts that would ensure that you are safe and any kind of risk is minimized.
The Earth’s lithosphere is generally made up of different slabs that are better known as plates and these ocean trenches normally occur where two plates meet and there is a thin divide in between. Hence, those who are interested in diving deeper to explore ocean trenches should also have a thorough knowledge about tectonic plates as the information can help them to learn more interesting facts about ocean trenches.
These trenches are common if there is a lot of tectonic activity happening and such areas are called subduction zones.
One easy way to spot ocean trenches below the sea is to locate volcanic islands. Most of the ocean trenches are very close to the volcanic islands, and this happens because one tectonic plate moves upwards then the other moves downwards creating an ocean trench.
Currently, Mariana Trench’s Challenger Deep is considered to be the deepest ocean trench in the world as its depth is more than the height of Mount Everest. However, few explorations have provided substantial information that aquatic life still exists in such deeper places even though there is no sunlight, and the water pressure is immense.
