The deepest point in the ocean is called the challenger deep and is located in the mariana trench. which of the following can be found in the trench?

high pressure

low light

warm temperature

photosynthetic organisms

Option (1)

Explanation:

The Mariana trench is found to be the deepest trench in the entire world. It has a depth of almost 11000 km. The Challenger deep is in located in this trench. The pressure is extremely high at the bottom of the ocean floor because of the increasing hydrostatic pressure. This hydrostatic pressure is defined as force (acting per unit area), that is applied by the liquid on any particular object under certain depth. This hydrostatic (fluid) pressure is directly proportional to the increasing depth of the ocean. For every 10 meters (approximate), there is an increase in the hydrostatic pressure by about 14.5 psi.  

So, extreme pressure is found at the bottom of this trench.

Hence, the correct answer is option (1).

we are putting to many trash.
