Deep sea trenches form by a process called "subduction" where the Earth's tectonic plates meet and push together. The deep sea can be a lonely place. Life here is sparse - the extreme conditions make survival difficult.
This is the deep sea. Oceanographers divide the majority of the ocean midwater into five broad zones. (NOAA) Most are familiar with the surface layer, which extends down 650 feet (200 m) and receives the most sunlight, allowing photosynthetic organisms like phytoplankton to convert sunlight to energy.
The deep sea is broadly defined as the ocean depth where light begins to fade, at an approximate depth of 200 m (660 ft) or the point of transition from continental shelves to continental slopes. Conditions within the deep sea are a combination of low temperatures, darkness, and high pressure.
